chore(3p/nix): unvendor tvix 0.1 r/4098

Nothing is using this now, and we'll likely never pick this up again,
but we learned a lot in the process.

Every now and then this breaks in some bizarre way on channel bumps
and it's just a waste of time to maintain that.

-<title>Release 0.11 (2007-12-31)</title>
-
-<para>Nix 0.11 has many improvements over the previous stable release.
-The most important improvement is secure multi-user support.  It also
-features many usability enhancements and language extensions, many of
-them prompted by NixOS, the purely functional Linux distribution based
-on Nix.  Here is an (incomplete) list:</para>
-
-
-<itemizedlist>
-
-
-  <listitem><para>Secure multi-user support.  A single Nix store can
-  now be shared between multiple (possible untrusted) users.  This is
-  an important feature for NixOS, where it allows non-root users to
-  install software.  The old setuid method for sharing a store between
-  multiple users has been removed.  Details for setting up a
-  multi-user store can be found in the manual.</para></listitem>
-
-
-  <listitem><para>The new command <command>nix-copy-closure</command>
-  gives you an easy and efficient way to exchange software between
-  machines.  It copies the missing parts of the closure of a set of
-  store path to or from a remote machine via
-  <command>ssh</command>.</para></listitem>
-
-
-  <listitem><para>A new kind of string literal: strings between double
-  single-quotes (<literal>''</literal>) have indentation
-  “intelligently” removed.  This allows large strings (such as shell
-  scripts or configuration file fragments in NixOS) to cleanly follow
-  the indentation of the surrounding expression.  It also requires
-  much less escaping, since <literal>''</literal> is less common in
-  most languages than <literal>"</literal>.</para></listitem>
-
-
-  <listitem><para><command>nix-env</command> <option>--set</option>
-  modifies the current generation of a profile so that it contains
-  exactly the specified derivation, and nothing else.  For example,
-  <literal>nix-env -p /nix/var/nix/profiles/browser --set
-  firefox</literal> lets the profile named
-  <filename>browser</filename> contain just Firefox.</para></listitem>
-
-
-  <listitem><para><command>nix-env</command> now maintains
-  meta-information about installed packages in profiles.  The
-  meta-information is the contents of the <varname>meta</varname>
-  attribute of derivations, such as <varname>description</varname> or
-  <varname>homepage</varname>.  The command <literal>nix-env -q --xml
-  --meta</literal> shows all meta-information.</para></listitem>
-
-
-  <listitem><para><command>nix-env</command> now uses the
-  <varname>meta.priority</varname> attribute of derivations to resolve
-  filename collisions between packages.  Lower priority values denote
-  a higher priority.  For instance, the GCC wrapper package and the
-  Binutils package in Nixpkgs both have a file
-  <filename>bin/ld</filename>, so previously if you tried to install
-  both you would get a collision.  Now, on the other hand, the GCC
-  wrapper declares a higher priority than Binutils, so the former’s
-  <filename>bin/ld</filename> is symlinked in the user
-  environment.</para></listitem>
-
-
-  <listitem><para><command>nix-env -i / -u</command>: instead of
-  breaking package ties by version, break them by priority and version
-  number.  That is, if there are multiple packages with the same name,
-  then pick the package with the highest priority, and only use the
-  version if there are multiple packages with the same
-  priority.</para>
-
-  <para>This makes it possible to mark specific versions/variant in
-  Nixpkgs more or less desirable than others.  A typical example would
-  be a beta version of some package (e.g.,
-  <literal>gcc-4.2.0rc1</literal>) which should not be installed even
-  though it is the highest version, except when it is explicitly
-  selected (e.g., <literal>nix-env -i
-  gcc-4.2.0rc1</literal>).</para></listitem>
-
-
-  <listitem><para><command>nix-env --set-flag</command> allows meta
-  attributes of installed packages to be modified.  There are several
-  attributes that can be usefully modified, because they affect the
-  behaviour of <command>nix-env</command> or the user environment
-  build script:
-
-    <itemizedlist>
-
-      <listitem><para><varname>meta.priority</varname> can be changed
-      to resolve filename clashes (see above).</para></listitem>
-
-      <listitem><para><varname>meta.keep</varname> can be set to
-      <literal>true</literal> to prevent the package from being
-      upgraded or replaced.  Useful if you want to hang on to an older
-      version of a package.</para></listitem>
-
-      <listitem><para><varname>meta.active</varname> can be set to
-      <literal>false</literal> to “disable” the package.  That is, no
-      symlinks will be generated to the files of the package, but it
-      remains part of the profile (so it won’t be garbage-collected).
-      Set it back to <literal>true</literal> to re-enable the
-      package.</para></listitem>
-
-    </itemizedlist>
-
-  </para></listitem>
-
-
-  <listitem><para><command>nix-env -q</command> now has a flag
-  <option>--prebuilt-only</option> (<option>-b</option>) that causes
-  <command>nix-env</command> to show only those derivations whose
-  output is already in the Nix store or that can be substituted (i.e.,
-  downloaded from somewhere).  In other words, it shows the packages
-  that can be installed “quickly”, i.e., don’t need to be built from
-  source.  The <option>-b</option> flag is also available in
-  <command>nix-env -i</command> and <command>nix-env -u</command> to
-  filter out derivations for which no pre-built binary is
-  available.</para></listitem>
-
-
-  <listitem><para>The new option <option>--argstr</option> (in
-  <command>nix-env</command>, <command>nix-instantiate</command> and
-  <command>nix-build</command>) is like <option>--arg</option>, except
-  that the value is a string.  For example, <literal>--argstr system
-  i686-linux</literal> is equivalent to <literal>--arg system
-  \"i686-linux\"</literal> (note that <option>--argstr</option>
-  prevents annoying quoting around shell arguments).</para></listitem>
-
-
-  <listitem><para><command>nix-store</command> has a new operation
-  <option>--read-log</option> (<option>-l</option>)
-  <parameter>paths</parameter> that shows the build log of the given
-  paths.</para></listitem>

-  <listitem><para>The option <option>--max-silent-time</option>
-  (corresponding to the configuration setting
-  <literal>build-max-silent-time</literal>) allows you to set a
-  timeout on builds — if a build produces no output on
-  <literal>stdout</literal> or <literal>stderr</literal> for the given
-  number of seconds, it is terminated.  This is useful for recovering
-  automatically from builds that are stuck in an infinite
-  loop.</para></listitem>
-
-
-  <listitem><para><command>nix-channel</command>: each subscribed
-  channel is its own attribute in the top-level expression generated
-  for the channel.  This allows disambiguation (e.g. <literal>nix-env
-  -i -A nixpkgs_unstable.firefox</literal>).</para></listitem>
-
-
-  <listitem><para>The substitutes table has been removed from the
-  database.  This makes operations such as <command>nix-pull</command>
-  and <command>nix-channel --update</command> much, much
-  faster.</para></listitem>
-
-
-  <listitem><para><command>nix-pull</command> now supports
-  bzip2-compressed manifests.  This speeds up
-  channels.</para></listitem>
-
-
-  <listitem><para><command>nix-prefetch-url</command> now has a
-  limited form of caching.  This is used by
-  <command>nix-channel</command> to prevent unnecessary downloads when
-  the channel hasn’t changed.</para></listitem>
-
-
-  <listitem><para><command>nix-prefetch-url</command> now by default
-  computes the SHA-256 hash of the file instead of the MD5 hash.  In
-  calls to <function>fetchurl</function> you should pass the
-  <literal>sha256</literal> attribute instead of
-  <literal>md5</literal>.  You can pass either a hexadecimal or a
-  base-32 encoding of the hash.</para></listitem>
-
-
-  <listitem><para>Nix can now perform builds in an automatically
-  generated “chroot”.  This prevents a builder from accessing stuff
-  outside of the Nix store, and thus helps ensure purity.  This is an
-  experimental feature.</para></listitem>
-
-
-  <listitem><para>The new command <command>nix-store
-  --optimise</command> reduces Nix store disk space usage by finding
-  identical files in the store and hard-linking them to each other.
-  It typically reduces the size of the store by something like
-  25-35%.</para></listitem>
-
-
-  <listitem><para><filename>~/.nix-defexpr</filename> can now be a
-  directory, in which case the Nix expressions in that directory are
-  combined into an attribute set, with the file names used as the
-  names of the attributes.  The command <command>nix-env
-  --import</command> (which set the
-  <filename>~/.nix-defexpr</filename> symlink) is
-  removed.</para></listitem>
-
-
-  <listitem><para>Derivations can specify the new special attribute
-  <varname>allowedReferences</varname> to enforce that the references
-  in the output of a derivation are a subset of a declared set of
-  paths.  For example, if <varname>allowedReferences</varname> is an
-  empty list, then the output must not have any references.  This is
-  used in NixOS to check that generated files such as initial ramdisks
-  for booting Linux don’t have any dependencies.</para></listitem>
-
-
-  <listitem><para>The new attribute
-  <varname>exportReferencesGraph</varname> allows builders access to
-  the references graph of their inputs.  This is used in NixOS for
-  tasks such as generating ISO-9660 images that contain a Nix store
-  populated with the closure of certain paths.</para></listitem>
-
-
-  <listitem><para>Fixed-output derivations (like
-  <function>fetchurl</function>) can define the attribute
-  <varname>impureEnvVars</varname> to allow external environment
-  variables to be passed to builders.  This is used in Nixpkgs to
-  support proxy configuration, among other things.</para></listitem>
