chore(3p/git): Unvendor git and track patches instead r/2903

This was vendored a long time ago under the expectation that keeping
it in sync with cgit would be easier this way, but it has proven not
to be a big issue.

On the other hand, a vendored copy of git is an annoying maintenance
burden. It is much easier to rebase the single (dottime) patch that we
have.

This removes the vendored copy of git and instead passes the git
source code to cgit via `pkgs.srcOnly`, which includes the applied
patch so that cgit can continue rendering dottime.

-GIT web Interface (gitweb) Installation
-=======================================
-
-First you have to generate gitweb.cgi from gitweb.perl using
-"make gitweb", then "make install-gitweb" appropriate files
-(gitweb.cgi, gitweb.js, gitweb.css, git-logo.png and git-favicon.png)
-to their destination. For example if git was (or is) installed with
-/usr prefix and gitwebdir is /var/www/cgi-bin, you can do
-
-	$ make prefix=/usr gitweb                            ;# as yourself
-	# make gitwebdir=/var/www/cgi-bin install-gitweb     ;# as root
-
-Alternatively you can use autoconf generated ./configure script to
-set up path to git binaries (via config.mak.autogen), so you can write
-instead
-
-	$ make configure                     ;# as yourself
-	$ ./configure --prefix=/usr          ;# as yourself
-	$ make gitweb                        ;# as yourself
-	# make gitwebdir=/var/www/cgi-bin \
-	       install-gitweb                ;# as root
-
-The above example assumes that your web server is configured to run
-[executable] files in /var/www/cgi-bin/ as server scripts (as CGI
-scripts).
-
-
-Requirements
-------------
-
- - Core git tools
- - Perl 5.8
- - Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename.
- - web server
-
-The following optional Perl modules are required for extra features
- - CGI::Fast and FCGI - for running gitweb as FastCGI script
- - HTML::TagCloud - for fancy tag cloud in project list view
- - HTTP::Date or Time::ParseDate - to support If-Modified-Since for feeds
-
-
-Build time configuration
-------------------------
-
-See also "How to configure gitweb for your local system" section below.
-
-- There are many configuration variables which affect building of
-  gitweb.cgi; see "default configuration for gitweb" section in main
-  (top dir) Makefile, and instructions for building gitweb target.
-
-  One of the most important is where to find the git wrapper binary. Gitweb
-  tries to find the git wrapper at $(bindir)/git, so you have to set $bindir
-  when building gitweb.cgi, or $prefix from which $bindir is derived. If
-  you build and install gitweb together with the rest of the git suite,
-  there should be no problems. Otherwise, if git was for example
-  installed from a binary package, you have to set $prefix (or $bindir)
-  accordingly.
-
-- Another important issue is where are git repositories you want to make
-  available to gitweb. By default gitweb searches for repositories under
-  /pub/git; if you want to have projects somewhere else, like /home/git,
-  use GITWEB_PROJECTROOT build configuration variable.
-
-  By default all git repositories under projectroot are visible and
-  available to gitweb. The list of projects is generated by default by
-  scanning the projectroot directory for git repositories. This can be
-  changed (configured) as described in "Gitweb repositories" section
-  below.
-
-  Note that gitweb deals directly with the object database, and does not
-  need a working directory; the name of the project is the name of its
-  repository object database, usually projectname.git for bare
-  repositories. If you want to provide gitweb access to non-bare (live)
-  repositories, you can make projectname.git a symbolic link under
-  projectroot linking to projectname/.git (but it is just
-  a suggestion).
-
-- You can control where gitweb tries to find its main CSS style file,
-  its JavaScript file, its favicon and logo with the GITWEB_CSS, GITWEB_JS
-  GITWEB_FAVICON and GITWEB_LOGO build configuration variables. By default
-  gitweb tries to find them in the same directory as gitweb.cgi script.
-
-- You can optionally generate minified versions of gitweb.js and gitweb.css
-  by defining the JSMIN and CSSMIN build configuration variables. By default
-  the non-minified versions will be used. NOTE: if you enable this option,
-  substitute gitweb.min.js and gitweb.min.css for all uses of gitweb.js and
-  gitweb.css in the help files.
-
-
-How to configure gitweb for your local system
----------------------------------------------
-
-You can specify the following configuration variables when building GIT:
-
- * GIT_BINDIR
-   Points where to find the git executable.  You should set it up to
-   the place where the git binary was installed (usually /usr/bin) if you
-   don't install git from sources together with gitweb.  [Default: $(bindir)]
- * GITWEB_SITENAME
-   Shown in the title of all generated pages, defaults to the server name
-   (SERVER_NAME CGI environment variable) if not set. [No default]
- * GITWEB_PROJECTROOT
-   The root directory for all projects shown by gitweb. Must be set
-   correctly for gitweb to find repositories to display.  See also
-   "Gitweb repositories" in the INSTALL file for gitweb.  [Default: /pub/git]
- * GITWEB_PROJECT_MAXDEPTH
-   The filesystem traversing limit for getting the project list; the number
-   is taken as depth relative to the projectroot.  It is used when
-   GITWEB_LIST is a directory (or is not set; then project root is used).
-   This is meant to speed up project listing on large work trees by limiting
-   search depth.  [Default: 2007]
- * GITWEB_LIST
-   Points to a directory to scan for projects (defaults to project root
-   if not set / if empty) or to a file with explicit listing of projects
-   (together with projects' ownership). See "Generating projects list
-   using gitweb" in INSTALL file for gitweb to find out how to generate
-   such file from scan of a directory. [No default, which means use root
-   directory for projects]
- * GITWEB_EXPORT_OK
-   Show repository only if this file exists (in repository).  Only
-   effective if this variable evaluates to true.  [No default / Not set]
- * GITWEB_STRICT_EXPORT
-   Only allow viewing of repositories also shown on the overview page.
-   This for example makes GITWEB_EXPORT_OK to decide if repository is
-   available and not only if it is shown.  If GITWEB_LIST points to
-   file with list of project, only those repositories listed would be
-   available for gitweb.  [No default]
- * GITWEB_HOMETEXT
-   Points to an .html file which is included on the gitweb project
-   overview page ('projects_list' view), if it exists.  Relative to
-   gitweb.cgi script.  [Default: indextext.html]
- * GITWEB_SITE_HTML_HEAD_STRING
-   html snippet to include in the <head> section of each page. [No default]
- * GITWEB_SITE_HEADER
-   Filename of html text to include at top of each page.  Relative to
-   gitweb.cgi script.  [No default]
- * GITWEB_SITE_FOOTER
-   Filename of html text to include at bottom of each page.  Relative to
-   gitweb.cgi script.  [No default]
- * GITWEB_HOME_LINK_STR
-   String of the home link on top of all pages, leading to $home_link
-   (usually main gitweb page, which means projects list).  Used as first
-   part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
-   [Default: projects]
- * GITWEB_SITENAME
-   Name of your site or organization to appear in page titles.  Set it
-   to something descriptive for clearer bookmarks etc.  If not set
-   (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
-   SERVER_NAME CGI environment variable is not set (e.g. if running
-   gitweb as standalone script).  [No default]
- * GITWEB_BASE_URL
-   Git base URLs used for URL to where fetch project from, i.e. full
-   URL is "$git_base_url/$project".  Shown on projects summary page.
-   Repository URL for project can be also configured per repository; this
-   takes precedence over URLs composed from base URL and a project name.
-   Note that you can setup multiple base URLs (for example one for
-   git:// protocol access, another for http:// access) from the gitweb
-   config file.  [No default]
- * GITWEB_CSS
-   Points to the location where you put gitweb.css on your web server
-   (or to be more generic, the URI of gitweb stylesheet).  Relative to the
-   base URI of gitweb.  Note that you can setup multiple stylesheets from
-   the gitweb config file.  [Default: static/gitweb.css (or
-   static/gitweb.min.css if the CSSMIN variable is defined / CSS minifier
-   is used)]
- * GITWEB_JS
-   Points to the location where you put gitweb.js on your web server
-   (or to be more generic URI of JavaScript code used by gitweb).
-   Relative to base URI of gitweb.  [Default: static/gitweb.js (or
-   static/gitweb.min.js if JSMIN build variable is defined / JavaScript
-   minifier is used)]
- * CSSMIN, JSMIN
-   Invocation of a CSS minifier or a JavaScript minifier, respectively,
-   working as a filter (source on standard input, minified result on
-   standard output).  If set, it is used to generate a minified version of
-   'static/gitweb.css' or 'static/gitweb.js', respectively.  *Note* that
-   minified files would have *.min.css and *.min.js extension, which is
-   important if you also set GITWEB_CSS and/or GITWEB_JS.  [No default]
- * GITWEB_LOGO
-   Points to the location where you put git-logo.png on your web server
-   (or to be more generic URI of logo, 72x27 size, displayed in top right
-   corner of each gitweb page, and used as logo for Atom feed).  Relative
-   to base URI of gitweb.  [Default: static/git-logo.png]
- * GITWEB_FAVICON
-   Points to the location where you put git-favicon.png on your web server
-   (or to be more generic URI of favicon, assumed to be image/png type;
-   web browsers that support favicons (website icons) may display them
-   in the browser's URL bar and next to site name in bookmarks).  Relative
-   to base URI of gitweb.  [Default: static/git-favicon.png]
- * GITWEB_CONFIG
-   This Perl file will be loaded using 'do' and can be used to override any
-   of the options above as well as some other options -- see the "Runtime
-   gitweb configuration" section below, and top of 'gitweb.cgi' for their
-   full list and description.  If the environment variable GITWEB_CONFIG
-   is set when gitweb.cgi is executed, then the file specified in the
-   environment variable will be loaded instead of the file specified
-   when gitweb.cgi was created.  [Default: gitweb_config.perl]
- * GITWEB_CONFIG_SYSTEM
-   This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
-   does not exist.  If the environment variable GITWEB_CONFIG_SYSTEM is set
-   when gitweb.cgi is executed, then the file specified in the environment
-   variable will be loaded instead of the file specified when gitweb.cgi was
-   created.  [Default: /etc/gitweb.conf]
- * HIGHLIGHT_BIN
-   Path to the highlight executable to use (must be the one from
-   http://www.andre-simon.de due to assumptions about parameters and output).
-   Useful if highlight is not installed on your webserver's PATH.
-   [Default: highlight]
-
-Build example
-~~~~~~~~~~~~~
-
-- To install gitweb to /var/www/cgi-bin/gitweb/, when git wrapper
-  is installed at /usr/local/bin/git, the repositories (projects)
-  we want to display are under /home/local/scm, and you do not use
-  minifiers, you can do
-
-	make GITWEB_PROJECTROOT="/home/local/scm" \
-	     GITWEB_JS="gitweb/static/gitweb.js" \
-	     GITWEB_CSS="gitweb/static/gitweb.css" \
-	     GITWEB_LOGO="gitweb/static/git-logo.png" \
-	     GITWEB_FAVICON="gitweb/static/git-favicon.png" \
-	     bindir=/usr/local/bin \
-	     gitweb
-
-	make gitwebdir=/var/www/cgi-bin/gitweb install-gitweb
-
-
-Gitweb config file
-------------------
-
-See also "Runtime gitweb configuration" section in README file
-for gitweb (in gitweb/README), and gitweb.conf(5) manpage.
-
-- You can configure gitweb further using the per-instance gitweb configuration file;
-  by default this is a file named gitweb_config.perl in the same place as
-  gitweb.cgi script. You can control the default place for the config file
-  using the GITWEB_CONFIG build configuration variable, and you can set it
-  using the GITWEB_CONFIG environment variable. If this file does not
-  exist, gitweb looks for a system-wide configuration file, normally
-  /etc/gitweb.conf. You can change the default using the
-  GITWEB_CONFIG_SYSTEM build configuration variable, and override it
-  through the GITWEB_CONFIG_SYSTEM environment variable.
-
-  Note that the GITWEB_CONFIG_SYSTEM system-wide configuration file is
-  only used for instances that lack per-instance configuration file.
-  You can use GITWEB_CONFIG_COMMON common system-wide configuration
-  file (normally /etc/gitweb-common.conf) to keep common default
-  settings that apply to all instances.  Settings from per-instance or
-  system-wide configuration file override those from common system-wide
-  configuration file.
-
-- The gitweb config file is a fragment of perl code. You can set variables
-  using "our $variable = value"; text from "#" character until the end
-  of a line is ignored. See perlsyn(1) for details.
-
-  See the top of gitweb.perl file for examples of customizable options.
-
-Config file example
-~~~~~~~~~~~~~~~~~~~
-
-To enable blame, pickaxe search, and snapshot support, while allowing
-individual projects to turn them off, put the following in your
-GITWEB_CONFIG file:
-
-	$feature{'blame'}{'default'} = [1];
-	$feature{'blame'}{'override'} = 1;
-
-	$feature{'pickaxe'}{'default'} = [1];
-	$feature{'pickaxe'}{'override'} = 1;
-
-	$feature{'snapshot'}{'default'} = ['zip', 'tgz'];
-	$feature{'snapshot'}{'override'} = 1;
-
-If you allow overriding for the snapshot feature, you can specify which
-snapshot formats are globally disabled. You can also add any command line
-options you want (such as setting the compression level). For instance,
-you can disable Zip compressed snapshots and set GZip to run at level 6 by
-adding the following lines to your $GITWEB_CONFIG:
-
-	$known_snapshot_formats{'zip'}{'disabled'} = 1;
-	$known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
-
-
-Gitweb repositories
--------------------
-
-By default gitweb shows all git repositories under single common repository
-root on a local filesystem; see description of GITWEB_PROJECTROOT build-time
-configuration variable above (and also of GITWEB_LIST).
-
-More advanced usage, like limiting access or visibility of repositories and
-managing multiple roots are described on gitweb manpage.

-Build time gitweb configuration
--------------------------------
-There are many configuration variables which affect building gitweb (among

-as `++GIT_BINDIR++` by their build-time values).
-
-Building and installing gitweb is described in gitweb's INSTALL file

-Gitweb obtains configuration data from the following sources in the
-following order:
-
-1. built-in values (some set during build stage),
-2. common system-wide configuration file (`GITWEB_CONFIG_COMMON`,
-   defaults to '/etc/gitweb-common.conf'),
-3. either per-instance configuration file (`GITWEB_CONFIG`, defaults to
-   'gitweb_config.perl' in the same directory as the installed gitweb),
-   or if it does not exists then system-wide configuration file
-   (`GITWEB_CONFIG_SYSTEM`, defaults to '/etc/gitweb.conf').
-
-Values obtained in later configuration files override values obtained earlier
-in above sequence.
-
-You can read defaults in system-wide GITWEB_CONFIG_SYSTEM from GITWEB_CONFIG
-by adding
-
-  read_config_file($GITWEB_CONFIG_SYSTEM);
-
-at very beginning of per-instance GITWEB_CONFIG file.  In this case
-settings in said per-instance file will override settings from
-system-wide configuration file.  Note that read_config_file checks
-itself that the $GITWEB_CONFIG_SYSTEM file exists.
-
-The most notable thing that is not configurable at compile time are the
-optional features, stored in the '%features' variable.
-
-Ultimate description on how to reconfigure the default features setting
-in your `GITWEB_CONFIG` or per-project in `project.git/config` can be found
-as comments inside 'gitweb.cgi'.
-
-See also gitweb.conf(5) manpage.
-
-
-Web server configuration
-------------------------
-Gitweb can be run as CGI script, as legacy mod_perl application (using
-ModPerl::Registry), and as FastCGI script.  You can find some simple examples
-in "Example web server configuration" section in INSTALL file for gitweb (in
-gitweb/INSTALL).
-
-See "Webserver configuration" and "Advanced web server setup" sections in
-gitweb(1) manpage.

-#      an unknown error occurred (e.g. the git binary died unexpectedly).
-# 503: The server is currently unavailable (because it is overloaded,

-GIT web interface (gitweb) - JavaScript
-=======================================
-
-This directory holds JavaScript code used by gitweb (GIT web interface).
-Scripts from there would be concatenated together in the order specified
-by gitweb/Makefile into gitweb/static/gitweb.js, during building of
-gitweb/gitweb.cgi (during gitweb building).  The resulting file (or its
-minification) would then be installed / deployed together with gitweb.
-
-Scripts in 'lib/' subdirectory compose generic JavaScript library,
-providing features required by gitweb but in no way limited to gitweb
-only.  In the future those scripts could be replaced by some JavaScript
-library / framework, like e.g. jQuery, YUI, Prototype, MooTools, Dojo,
-ExtJS, Script.aculo.us or SproutCore.
-
-All scripts that manipulate gitweb output should be put outside 'lib/',
-directly in this directory ('gitweb/static/js/').  Those scripts would
-have to be rewritten if gitweb moves to using some JavaScript library.
-
-See also comments in gitweb/Makefile.
