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 1.7 (2014-04-11)</title>
-
-<para>In addition to the usual bug fixes, this release has the
-following new features:</para>
-
-<itemizedlist>
-
-  <listitem>
-    <para>Antiquotation is now allowed inside of quoted attribute
-    names (e.g. <literal>set."${foo}"</literal>). In the case where
-    the attribute name is just a single antiquotation, the quotes can
-    be dropped (e.g. the above example can be written
-    <literal>set.${foo}</literal>). If an attribute name inside of a
-    set declaration evaluates to <literal>null</literal> (e.g.
-    <literal>{ ${null} = false; }</literal>), then that attribute is
-    not added to the set.</para>
-  </listitem>
-
-  <listitem>
-    <para>Experimental support for cryptographically signed binary
-    caches.  See <link
-    xlink:href="https://github.com/NixOS/nix/commit/0fdf4da0e979f992db75cc17376e455ddc5a96d8">the
-    commit for details</link>.</para>
-  </listitem>
-
-  <listitem>
-    <para>An experimental new substituter,
-    <command>download-via-ssh</command>, that fetches binaries from
-    remote machines via SSH.  Specifying the flags <literal>--option
-    use-ssh-substituter true --option ssh-substituter-hosts
-    <replaceable>user@hostname</replaceable></literal> will cause Nix
-    to download binaries from the specified machine, if it has
-    them.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-store -r</command> and
-    <command>nix-build</command> have a new flag,
-    <option>--check</option>, that builds a previously built
-    derivation again, and prints an error message if the output is not
-    exactly the same. This helps to verify whether a derivation is
-    truly deterministic.  For example:
-
-<screen>
-$ nix-build '&lt;nixpkgs>' -A patchelf
-<replaceable>…</replaceable>
-$ nix-build '&lt;nixpkgs>' -A patchelf --check
-<replaceable>…</replaceable>
-error: derivation `/nix/store/1ipvxs…-patchelf-0.6' may not be deterministic:
-  hash mismatch in output `/nix/store/4pc1dm…-patchelf-0.6.drv'
-</screen>
-
-    </para>
-
-  </listitem>
-
-  <listitem>
-    <para>The <command>nix-instantiate</command> flags
-    <option>--eval-only</option> and <option>--parse-only</option>
-    have been renamed to <option>--eval</option> and
-    <option>--parse</option>, respectively.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-instantiate</command>,
-    <command>nix-build</command> and <command>nix-shell</command> now
-    have a flag <option>--expr</option> (or <option>-E</option>) that
-    allows you to specify the expression to be evaluated as a command
-    line argument.  For instance, <literal>nix-instantiate --eval -E
-    '1 + 2'</literal> will print <literal>3</literal>.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-shell</command> improvements:</para>
-
-    <itemizedlist>
-
-      <listitem>
-        <para>It has a new flag, <option>--packages</option> (or
-        <option>-p</option>), that sets up a build environment
-        containing the specified packages from Nixpkgs. For example,
-        the command
-
-<screen>
-$ nix-shell -p sqlite xorg.libX11 hello
-</screen>
-
-        will start a shell in which the given packages are
-        present.</para>
-      </listitem>
-
-      <listitem>
-        <para>It now uses <filename>shell.nix</filename> as the
-        default expression, falling back to
-        <filename>default.nix</filename> if the former doesn’t
-        exist.  This makes it convenient to have a
-        <filename>shell.nix</filename> in your project to set up a
-        nice development environment.</para>
-      </listitem>
-
-      <listitem>
-        <para>It evaluates the derivation attribute
-        <varname>shellHook</varname>, if set. Since
-        <literal>stdenv</literal> does not normally execute this hook,
-        it allows you to do <command>nix-shell</command>-specific
-        setup.</para>
-      </listitem>
-
-      <listitem>
-        <para>It preserves the user’s timezone setting.</para>
-      </listitem>
-
-    </itemizedlist>
-
-  </listitem>
-
-  <listitem>
-    <para>In chroots, Nix now sets up a <filename>/dev</filename>
-    containing only a minimal set of devices (such as
-    <filename>/dev/null</filename>). Note that it only does this if
-    you <emphasis>don’t</emphasis> have <filename>/dev</filename>
-    listed in your <option>build-chroot-dirs</option> setting;
-    otherwise, it will bind-mount the <literal>/dev</literal> from
-    outside the chroot.</para>
-
-    <para>Similarly, if you don’t have <filename>/dev/pts</filename> listed
-    in <option>build-chroot-dirs</option>, Nix will mount a private
-    <literal>devpts</literal> filesystem on the chroot’s
-    <filename>/dev/pts</filename>.</para>
-
-  </listitem>
-
-  <listitem>
-    <para>New built-in function: <function>builtins.toJSON</function>,
-    which returns a JSON representation of a value.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-env -q</command> has a new flag
-    <option>--json</option> to print a JSON representation of the
-    installed or available packages.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-env</command> now supports meta attributes with
-    more complex values, such as attribute sets.</para>
-  </listitem>
-
-  <listitem>
-    <para>The <option>-A</option> flag now allows attribute names with
-    dots in them, e.g.
-
-<screen>
-$ nix-instantiate --eval '&lt;nixos>' -A 'config.systemd.units."nscd.service".text'
-</screen>
-
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>The <option>--max-freed</option> option to
-    <command>nix-store --gc</command> now accepts a unit
-    specifier. For example, <literal>nix-store --gc --max-freed
-    1G</literal> will free up to 1 gigabyte of disk space.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-collect-garbage</command> has a new flag
-    <option>--delete-older-than</option>
-    <replaceable>N</replaceable><literal>d</literal>, which deletes
-    all user environment generations older than
-    <replaceable>N</replaceable> days.  Likewise, <command>nix-env
-    --delete-generations</command> accepts a
-    <replaceable>N</replaceable><literal>d</literal> age limit.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now heuristically detects whether a build failure was
-    due to a disk-full condition. In that case, the build is not
-    flagged as “permanently failed”. This is mostly useful for Hydra,
-    which needs to distinguish between permanent and transient build
-    failures.</para>
-  </listitem>
-
-  <listitem>
-    <para>There is a new symbol <literal>__curPos</literal> that
-    expands to an attribute set containing its file name and line and
-    column numbers, e.g. <literal>{ file = "foo.nix"; line = 10;
-    column = 5; }</literal>.  There also is a new builtin function,
-    <varname>unsafeGetAttrPos</varname>, that returns the position of
-    an attribute.  This is used by Nixpkgs to provide location
-    information in error messages, e.g.
-
-<screen>
-$ nix-build '&lt;nixpkgs>' -A libreoffice --argstr system x86_64-darwin
-error: the package ‘libreoffice-4.0.5.2’ in ‘.../applications/office/libreoffice/default.nix:263’
-  is not supported on ‘x86_64-darwin’
-</screen>
-
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>The garbage collector is now more concurrent with other Nix
-    processes because it releases certain locks earlier.</para>
-  </listitem>
-
-  <listitem>
-    <para>The binary tarball installer has been improved.  You can now
-    install Nix by running:
-
-<screen>
-$ bash &lt;(curl https://nixos.org/nix/install)
-</screen>
-
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>More evaluation errors include position information. For
-    instance, selecting a missing attribute will print something like
-
-<screen>
-error: attribute `nixUnstabl' missing, at /etc/nixos/configurations/misc/eelco/mandark.nix:216:15
-</screen>
-
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>The command <command>nix-setuid-helper</command> is
-    gone.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix no longer uses Automake, but instead has a
-    non-recursive, GNU Make-based build system.</para>
-  </listitem>
-
-  <listitem>
-    <para>All installed libraries now have the prefix
-    <literal>libnix</literal>.  In particular, this gets rid of
-    <literal>libutil</literal>, which could clash with libraries with
-    the same name from other packages.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now requires a compiler that supports C++11.</para>
-  </listitem>
