merge(3p/git): Merge git subtree at v2.29.2 r/1890

This also bumps the stable nixpkgs to 20.09 as of 2020-11-21, because
there is some breakage in the git build related to the netrc
credentials helper which someone has taken care of in nixpkgs.

The stable channel is not used for anything other than git, so this
should be fine.

-Remotes configuration API
-=========================
-
-The API in remote.h gives access to the configuration related to
-remotes. It handles all three configuration mechanisms historically
-and currently used by Git, and presents the information in a uniform
-fashion. Note that the code also handles plain URLs without any
-configuration, giving them just the default information.
-
-struct remote
--------------
-
-`name`::
-
-	The user's nickname for the remote
-
-`url`::
-
-	An array of all of the url_nr URLs configured for the remote
-
-`pushurl`::
-
-	An array of all of the pushurl_nr push URLs configured for the remote
-
-`push`::
-
-	 An array of refspecs configured for pushing, with
-	 push_refspec being the literal strings, and push_refspec_nr
-	 being the quantity.
-
-`fetch`::
-
-	An array of refspecs configured for fetching, with
-	fetch_refspec being the literal strings, and fetch_refspec_nr
-	being the quantity.
-
-`fetch_tags`::
-
-	The setting for whether to fetch tags (as a separate rule from
-	the configured refspecs); -1 means never to fetch tags, 0
-	means to auto-follow tags based on the default heuristic, 1
-	means to always auto-follow tags, and 2 means to fetch all
-	tags.
-
-`receivepack`, `uploadpack`::
-
-	The configured helper programs to run on the remote side, for
-	Git-native protocols.
-
-`http_proxy`::
-
-	The proxy to use for curl (http, https, ftp, etc.) URLs.
-
-`http_proxy_authmethod`::
-
-	The method used for authenticating against `http_proxy`.
-
-struct remotes can be found by name with remote_get(), and iterated
-through with for_each_remote(). remote_get(NULL) will return the
-default remote, given the current branch and configuration.
-
-struct refspec
---------------
-
-A struct refspec holds the parsed interpretation of a refspec.  If it
-will force updates (starts with a '+'), force is true.  If it is a
-pattern (sides end with '*') pattern is true.  src and dest are the
-two sides (including '*' characters if present); if there is only one
-side, it is src, and dst is NULL; if sides exist but are empty (i.e.,
-the refspec either starts or ends with ':'), the corresponding side is
-"".
-
-An array of strings can be parsed into an array of struct refspecs
-using parse_fetch_refspec() or parse_push_refspec().
-
-remote_find_tracking(), given a remote and a struct refspec with
-either src or dst filled out, will fill out the other such that the
-result is in the "fetch" specification for the remote (note that this
-evaluates patterns and returns a single result).
-
-struct branch
--------------
-
-Note that this may end up moving to branch.h
-
-struct branch holds the configuration for a branch. It can be looked
-up with branch_get(name) for "refs/heads/{name}", or with
-branch_get(NULL) for HEAD.
-
-It contains:
-
-`name`::
-
-	The short name of the branch.
-
-`refname`::
-
-	The full path for the branch ref.
-
-`remote_name`::
-
-	The name of the remote listed in the configuration.
-
-`merge_name`::
-
-	An array of the "merge" lines in the configuration.
-
-`merge`::
-
-	An array of the struct refspecs used for the merge lines. That
-	is, merge[i]->dst is a local tracking ref which should be
-	merged into this branch by default.
-
-`merge_nr`::
-
-	The number of merge configurations
-
-branch_has_merge_config() returns true if the given branch has merge
-configuration given.
-
-Other stuff
------------
-
-There is other stuff in remote.h that is related, in general, to the
-process of interacting with remotes.
