It seems like the amount of logging is causing things to move a little

Included fixes for random breakage:
* 3p/awscli: pick from the stable channel; it is broken on unstable
* 3p/googletest: bumped version & removed patches that nixpkgs applies
* 3p/lisp/cffi: bumped library version for SBCL compat
* 3p/nix: fix libsystemd attribute
* 3p/nix: reformatted (clang-format handling of ternaries changed)
* glittershark/home: Use home-manager from nixkpgs
* glittershark/kernel: bumped linux-ck patch hash
* glittershark/kernel: removed "patch patch"
* multi/whitby: Use home-manager from nixpkgs
* tazjin/frog: drop Sourcetrail (it doesn't build currently)
Note that in addition to these changes, some previous CLs updated the
versions of git and cgit which was necessary for this channel bump,
but which could not be done in the same commit due to the nature of
the subtree merges.

The command line options --arg and --argstr that are used by a bunch of
CLI commands to pass arguments to top-level functions in files go
through the same code-path as auto-calling top-level functions with
their default arguments - this, however, was only passing the arguments
that were *explicitly* mentioned in the formals of the function - in the
case of an as-pattern with an ellipsis (eg args @ { ... }) extra passed
arguments would get omitted. This fixes that to instead pass *all*
specified auto args in the case that our function has an ellipsis.

Previously, MixEvalArgs (a generic data type used to handle --arg,
--argstr, and -I arguments to `nix-build`, `nix eval`, etc.) was storing
the difference between --arg and --argstr by prepending a single
character (either 'E' or 'S') to the value of the arg. This is messy and
un-type-safe, so this commit refactors that to use a proper enum and a
std::pair, which allows us to add a switch and get totality checking.
yay, types!

This was probably introduced by the std::vector refactoring, and the

was for disabling it seems to be gone, so we're re-enabling it.

We have decided that leaking memory is a better fate than random,
non-debuggable memory corruption. Future CLs will begin changing
various fields to std::unique_ptr and std::shared_ptr.
It turns out that disabling the GC does not have disasterous impact.
The Nix evaluator only runs on the client CLI, never in any long-
running process. Even the REPL does not leak too badly under this
change, because it uses one EvalState for the duration of the REPL.
Building an explicitly tracing garbage collector is likely in the
future of this project, but that giant amount of work cannot be
done under a nix evaluator that is constantly crashing. We need to
restore development velocity here, and this is the best way we've
figured out to do it.

provided an empty string is a behavior that absl inherited from legacy

behavior provided by the SkipEmpty option. Switch all calls to use

Only libexpr depends on the garbage collector, specifically only
instantiations of EvalState actually require the GC to be initialised.
Rather than always starting it for the whole program, even if it is
not needed, this change moves the GC initialisation into libexpr,
guarded by absl::call_once.
This should make it possible to run the nix daemon without the garbage
collector interfering, granted that things are correcty separated and
the daemon does not actually invoke the evaluator.
Based on my investigation so far, the daemon logic itself does not
require libexpr to be present at all - so I think it is safe - but the
current monobinary might have some tricks up its sleeve that will
cause problems for us. We can deal with those if they arise.

This is the shared object equivalent of builtins.exec, or a plugins

Plugins seem to not really be used anywhere (I can find one plugin
that's actually defined, and it doesn't seem very useful, especially
since we got rid of builtins.exec) and their presence is adding
additional complexity and potential sources of bugs to an already
unsteady refactor. At some point we may want to bring back
something *like* plugins, but their design will likely be different and
it will definitely be after we have a functioning Nix again.
