Reverts "Bump channel to a NixOS 20.03 release commit".
This reverts commit a629d7fdd4.
This commit moves to a 20.03 release commit, in which building
Chromium with VAAPI is broken.
These patches enable hardware-accelerated video decoding, which is
useful for Stadia.
The main issue with this is that Hydra doesn't currently cache
Chromium with these patches, which means that it is built from scratch
which takes in the order of 5 hours on an otherwise unused nugget.
Builds ffmpeg with CUDA Toolkit as a dependency, which includes a
library called "libnpp" that provides something related to hardware
accelerated video stream resizing.

This removes the ASDF system definition for Gemma and switches the
code over to buildLisp.
The program builds (including some terrifying hacks to get the
frontend to work), but there are some bizarre runtime issues that I
need to debug.
This is pretty much exactly the derivation from nixpkgs, with some
things removed to reduce the closure size (e.g. the various formatters
used in the default cgit version, which are replaced by cheddar in my
setup).
This overrides the upstream derivation to:
* use local sources
* build `git send-email`
It also calls autoreconf before building because files that are
included in the git distribution tarball (which the normal derivation
uses) are missing from source.
Similar to buildGo.nix, the library derivations carry information
about their dependencies which is merged when a load file is
instantiated.
The load files are created when compiling libraries, but will in the
future also be created when wrapping SBCL and dumping images.
This uses Nix to inject the path to the syntax highlighting assets
that ship with the bat source code into the cheddar build at compile
time, where the Rust compiler then inserts it into the binary via
macros.
bat has a lot of custom syntax highlighting definitions that they
collected from all over the place (including for languages like Nix!)
and this makes them accessible to cheddar.
Also if you're reading this, can you just take a moment to appreciate
how incredible it is that Nix just lets us do something like this?!
Packages the telega-server binary and adds the required mode into
Emacs.
Unread message count is displayed in the modeline, which is neat.
Probably need to figure out some key bindings for this.
This enables usage of __dispatch.sh from anywhere, even outside of the
depot.
Specifically this means I can add `~/depot/bin` to my $PATH and all
the registered tools work from anywhere.
