This improves our Bundler integration (i.e. `bundlerEnv`).
Before describing the implementation differences, I'd like to point a
breaking change: buildRubyGem now expects `gemName` and `version` as
arguments, rather than a `name` attribute in the form of
"<gem-name>-<version>".
Now for the differences in implementation.
The previous implementation installed all gems at once in a single
derivation. This was made possible by using a set of monkey-patches to
prevent Bundler from downloading gems impurely, and to help Bundler
find and activate all required gems prior to installation. This had
several downsides:
* The patches were really hard to understand, and required subtle
interaction with the rest of the build environment.
* A single install failure would cause the entire derivation to fail.
The new implementation takes a different approach: we install gems into
separate derivations, and then present Bundler with a symlink forest
thereof. This has a couple benefits over the existing approach:
* Fewer patches are required, with less interplay with the rest of the
build environment.
* Changes to one gem no longer cause a rebuild of the entire dependency
graph.
* Builds take 20% less time (using gitlab as a reference).
It's unfortunate that we still have to muck with Bundler's internals,
though it's unavoidable with the way that Bundler is currently designed.
There are a number improvements that could be made in Bundler that would
simplify our packaging story:
* Bundler requires all installed gems reside within the same prefix
(GEM_HOME), unlike RubyGems which allows for multiple prefixes to
be specified through GEM_PATH. It would be ideal if Bundler allowed
for packages to be installed and sourced from multiple prefixes.
* Bundler installs git sources very differently from how RubyGems
installs gem packages, and, unlike RubyGems, it doesn't provide a
public interface (CLI or programmatic) to guide the installation of a
single gem. We are presented with the options of either
reimplementing a considerable portion Bundler, or patch and use parts
of its internals; I choose the latter. Ideally, there would be a way
to install gems from git sources in a manner similar to how we drive
`gem` to install gem packages.
* When a bundled program is executed (via `bundle exec` or a
binstub that does `require 'bundler/setup'`), the setup process reads
the Gemfile.lock, activates the dependencies, re-serializes the lock
file it read earlier, and then attempts to overwrite the Gemfile.lock
if the contents aren't bit-identical. I think the reasoning is that
by merely running an application with a newer version of Bundler, you'll
automatically keep the Gemfile.lock up-to-date with any changes in the
format. Unfortunately, that doesn't play well with any form of
packaging, because bundler will immediately cause the application to
abort when it attempts to write to the read-only Gemfile.lock in the
store. We work around this by normalizing the Gemfile.lock with the
version of Bundler that we'll use at runtime before we copy it into
the store. This feels fragile, but it's the best we can do without
changes upstream, or resorting to more delicate hacks.
With all of the challenges in using Bundler, one might wonder why we
can't just cut Bundler out of the picture and use RubyGems. After all,
Nix provides most of the isolation that Bundler is used for anyway.
The problem, however, is that almost every Rails application calls
`Bundler::require` at startup (by way of the default project templates).
Because bundler will then, by default, `require` each gem listed in the
Gemfile, Rails applications are almost always written such that none of
the source files explicitly require their dependencies. That leaves us
with two options: support and use Bundler, or maintain massive patches
for every Rails application that we package.

After trying with a dozen files, it seems the bs1770gain backend is much
more reliable than the audiotools backend and especially does a better
job (well, compared to audiotools which either does doing nothing at all
or throws an exception) when used on alboms that contain different
sample rates/sizes.
Additionally, we already had a few issues regarding the audiotools
backend, even to the extent that @sampsyco almost wanted to drop it
upstream (see sampsyco/beets#1342).
Also related issues are #10376 and sampsyo/beets#1592.

The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
I have to admit that I did very poor testing in d7307d8 and didn't
notice that the "badfiles" plugin relies on mp3val (thanks to @devhell
for packaging in 6e1ef13) and flac to be actually useful.
We now patch in the store locations of these binaries and make
"badfiles" an optional dependency (though enabled by default).
Now, I have tested "beet bad" on my whole music collection and it worked
fine (well, it has found errors... but that's what it is for).

The configure script requires libogg in both the paths of libopus and
libvorbis. Because is isn't true for the libopus and libvorbis
derivations in NixOS and patching the configure script is a bit tedious,
a temporary environment with libogg, libvorbis & libopus is used.
I presume there's something about how github creates the .zip files such
that they can change SHA.
Please note: this is a very outdated version of pasystray---I don't know
if that's intentional, but perhaps a better strategy would be to update
it wholesale.
We're passing glibcLocales to the tests directly, so we don't pollute
the builder's environment anyway, so no reason to override anything
there.

We can now finally drop the mediafile and test fix patches, because they
were already coming from the upstream repository and are now included in
the release.
Also, this release brings two new plugins:
* permissions: Fix permissions on music files as they are imported.
* plexupdate: Notify a Plex server when the database changes.
The echonest_tempo plugin has finally been removed and so we can drop it
entirely. No plugin as of now tries to do interactive prompts on "beet
config" anymore, so we can test *all* plugins and without providing
dummy options.

See, that's why I hate the gregorian calendar and new years eve: People
tend to celebrate things that are absolutely irrelevant, like this
comment.
The test however assumed that either beets or its test suite would never
survive 2015, so this test should assure it won't survive in >= 2015 :-)
Anyway, the patch is from upstream master, so we can drop it once 1.3.10
is released.

Beets tries to load oll activated plugins on "beet config -e" (however
only on the second run, thus the dummy), so we just pass all activated
plugins into a generated config file and bail out on any errors.

The reason for doing this is in order to not forget about possible
dependencies in new upstream releases, so if upstream is introducing a
new plugin where we're lacking dependencies, the build will fail on our
side and we can check whether we'll need those.

Using commands such as mp3gain and aacgain is only the default for
backwards-compatible reasons. However, on Nix(OS), we would have to
either patch those tools into beets or rely on an impurity, so let's
depend on audiotools and also default to that backend.
Of course, there is also a GStreamer backend, but it comes with a hell
of additional dependencies (which not only cover audio files), which is
why I decided against defaulting to GStreamer and package audiotools
instead (in eecd932).

This also fleshes out/fixes the unit tests, which I've used for
gathering the individual requirements.
Along various Python dependencies we now also have a build-time
dependency on bashInteractive and a runtime dependency on
bashCompletion, which is needed for command line completion to work
correctly.
However, some tests for the shell completion fail at the moment, so I've
disabled them for now.
The patch for fixing mediafile codec info is a modified version of
sampsyo/beets@903e88a, where I just dropped the second hunk modifying
the changelog. It is already merged to master and thus expected to be in
the next upstream version.

The reason for doing this is because the package on PyPI is missing some

The primary use of beets is not as a Python library and users usually
would expect to install it into the env using "nix-env -i beets" rather
than "nix-env -i pythonX.Y-beets".
Having beets in its own package directory also allows for better
customization, where we're going to implement attributes that can be
used to turn on/off various features and plugins.
