This replaces the ad-hoc tuples used in the different feature gate files
and unifies their content into a common type, leading to more readable
matches and other good stuff that comes from having named fields. It
also contains the description of each feature as extracted from the doc
comment.
Feature gate definitions were split into multiple files in #63824 but
tidy kept reporting the hard-coded path. Now, it shows the full path
to the correct file.
bootstrap: Merge the libtest build step with libstd
Since its inception rustbuild has always worked in three stages: one for
libstd, one for libtest, and one for rustc. These three stages were
architected around crates.io dependencies, where rustc wants to depend
on crates.io crates but said crates don't explicitly depend on libstd,
requiring a sysroot assembly step in the middle. This same logic was
applied for libtest where libtest wants to depend on crates.io crates
(`getopts`) but `getopts` didn't say that it depended on std, so it
needed `std` built ahead of time.
Lots of time has passed since the inception of rustbuild, however,
and we've since gotten to the point where even `std` itself is depending
on crates.io crates (albeit with some wonky configuration). This
commit applies the same logic to the two dependencies that the `test`
crate pulls in from crates.io, `getopts` and `unicode-width`. Over the
many years since rustbuild's inception `unicode-width` was the only
dependency picked up by the `test` crate, so the extra configuration
necessary to get crates building in this crate graph is unlikely to be
too much of a burden on developers.
After this patch it means that there are now only two build phasese of
rustbuild, one for libstd and one for rustc. The libtest/libproc_macro
build phase is all lumped into one now with `std`.
This was originally motivated by rust-lang/cargo#7216 where Cargo was
having to deal with synthesizing dependency edges but this commit makes
them explicit in this repository.
Refactor `feature_gate.rs` into modules & cleanup
Split `src/libsyntax/feature_gate.rs` into `src/libsyntax/feature_gate/` with files:
- `accepted.rs` (accepted feature gates)
- `removed.rs` (...)
- `active.rs` (...)
- `builtin_attrs.rs` (definition of builtin attributes and their gates as well as gating `cfg` flags)
- `check.rs` (post expansion checking of feature gates)
- `mod.rs` (just reexports)
Additionally, `tidy.rs` is adjusted to respect the new scheme.
Also, `builtin_attrs.rs` sees some cleanup, organization, and DSL-ification to reduce repetition.
This is probably best read commit-by-commit I think.

Fix confusion in theme picker functions
To reproduce the bug currently: click on the theme picker button twice (to show it then hide it). Then click anywhere else: the dropdown menu appears again.
The problem was coming from a confusion of what the `hideThemeButtonState` and `showThemeButtonState` were supposed to do. I switched their codes and updated the `switchThemeButtonState` function. It now works as expected.
