Subject: [PATCH 3/7] ghdl: 0.37 -> unstable-2021.01.14

This unreleased version of GHDL fixes a bunch of bugs. It also contains
a few internal API changes for synthesis support -- required by the GHDL
yosys plugin.

Ideally, we can just remove this when 0.38 comes out.

Subject: [PATCH 4/7] yosys: enable loading "out of band" plugins

By default, when yosys looks for plugins with the `-m` flag or `plugin`
command, it always looks in `YOSYS_PREFIX/share/yosys/plugins` for a
`.so` file, and loads that.

By design, this is intended to be a single, global, mutable location
such as `/usr/share/yosys/...` on disk, and plugins are supposed to
install their `.so` files here after yosys is installed, and they all
coexist together. Obviously, this won't work for us, but users might
expect these plugins to still work. More importantly, they won't want to
add special cases to their build systems.

Instead, to allow Nix users to use yosys plugins with the same UX (e.g.
natively call `plugin bluespec` or `-m ghdl`), we add a patch to yosys
that allows it to search a new `NIX_YOSYS_PLUGIN_DIRS` search path
environment variable. In tandem, we add a setup hook that adds to this
search path if a package has a `$out/share/yosys/plugins` directory.

Thus, it's enough to just include `yosys`, and any package that has a
yosys plugin in `$out/share/yosys/plugins`, and you can load it with
`-m` or the `plugin` command.

We could use a style like the haskellPackages set, where the set of
packages are "encased" in a lambda, and we pass packages that are
compatible with that version of the compiler:

    haskell.packages.ghc8102.ghcWithPackages (p: with p; [ ... ])

but, realistically, there will probably only ever be one version of
yosys and one set of compatible plugins, so this seems overdone.

Subject: [PATCH 5/7] init: experimental yosys-{bluespec, ghdl} plugins

These plugins can be included in a closure, along with the `yosys`
derivation, and they will be automatically picked up for use. For
example, this allows you to include 'yosys-bluespec' in your
`buildInputs`, and then immediately run:

    $ nix-shell -p yosys yosys-bluespec yosys-ghdl
    $ yosys -m bluespec -p 'help read_bluespec'
    $ yosys -m ghdl -p 'help ghdl'

These two plugins are a bit experimental, admittedly, but they are good,
clean examples of how to write and use the yosys plugin infrastructure,
and make it easy to test updates, etc.
