The new version contains
- A bug fix for the bucketed allocator (we don't currently use it)
- A few fixes that can happen when requesting large enough allocation sizes to cause integer overflows. At the moment we never request an allocation larger than 512px so we are safe but it's still good to stay up to date.

Fixes errors like:
dependency (nix) specification is ambiguous. Only one of `branch`, `tag` or `rev` is allowed.
I've left the most specific dependency, but for wgpu the rev is not
right, so I've kept the branch which effectively preserves behavior.

comedy 0.2.0 no longer impls Fail itself. By reenabling the default features
(including std) of failure, the blanket impl will cover that. These features
were disabled to remove a dependency on backtrace, but since bug 1608157 we
are using a version of failure without backtrace by default so that is no
longer needed.

* Use `nsACString` across the FFI (no need for `ffi-support` anymore)

Events are special in that they are generic over the type of extra keys
they can handle.
This makes them unsuitable to store in simple hashmaps, as (nearly) every event metric is its own type.
To still keep the nice and statically-checked Rust API, but also have
C++ and JS APIs we defer it all to a big ol' lookup table using `match`
at `record()` time.
Note:
While passing `extras` works it's not yet perfect.
The C++ API is hard to use.
The JavaScript API works, but is not documented.
Additionally `testGetValue` doesn't work yet for events in either language.

Instantiating a wasm library duplicates a file descriptor for /dev/null 3 times to be used as input, output and error streams for the wasm sandboxed code. When a lot of sandboxes are created and destroyed, a lot of descriptors are duplicated and closed. While this should be fine, POSIX does not seem to happy with the opening and closing of many file descriptors --- this could perhaps be some strange interaction with Firefox's seccomp filters and cross-process file descriptor handling as it is difficult to repro this outside of firefox.
However, the simpler fix here was to just eliminate the duplication of /dev/null and return an error when input, output or error streams are accessed by wasm sandboxed code. This means calls to printf will fail, but no code I know off actually checks the int error code returned by printf and this change is certainly compatible with existing sandboxed components.

The changes should be trivial.
The third_party changes are up for review in
https://github.com/servo/rust-cssparser/pull/277 (and of course I'll
land with a bump to 0.28 rather than the override after that gets r+'d).
The basic idea is that with this we have the actual start offset of the
rule, so we wouldn't include html comments or other invalid stuff we
discard during sanitization in bug 1680084. But that's a separate
change.

This fixes the failures in bug 1671573 and just works thanks to the
invalidation improvements I did for :is / :where.
Added a couple tests for invalidation which is the tricky bit. 001 is a
very straight-forward test, 002 is the :is test but with :is() replaced
by double-:not().
This also fixes default namespaces inside :is() / :where(), which are
supposed to get ignored, but aren't. Added tests for that and for the
pre-existing :not() behavior which Chrome doesn't quite get right.

The CGFonts end up in a cache that we don't want. Creating the CTFonts
directly should avoid this.
Notes:
add_native_font normally takes a CGFont and we need a CTFontDescriptor
so we convert to postscript name and then postscript name to
CTFontDescriptor. This is wasteful but avoids needing to change the
external API.
To avoid copying the data in the Vec we use a CFAllocator to wrap the
Vec for use by CFData

This patch adds a task that is dispatched to the background thread when TRR
is first enabled. This may mean during the TRRService initialization at
startup or later when the pref is flipped.
The task will call into rust_parse_etc_hosts which does the actual file
opening and parsing. We pass the path to the file, that being either
/etc/hosts or the Windows equivalent obtained by calling
SHGetSpecialFolderPathA.
The rust code opens the file and proceeds to read it line by line while
accumulating all the hostnames in an array. Since these files can be
quite large, on the order of several megabytes, we need to make sure we
don't block shutdown doing this - so once more than 100 domains have
accumulated in the array we call back into C++ code to add them to the
exclusion list. The callback will return true if we should continue to
parse the file or false otherwise.
We also change the tests to use "excluded" rather than localhost when
testing the excluded-domains prefs, since localhost is unually present
in /etc/hosts and may interfere with the test.
We also use an atomic sTRRServicePtr to make sure that we don't have
a data race between the TRRService being freed and the callbacks of the
parsing.

The conversion was done with c2rust and then manually cleaned up some.
There's still lots of unsafe code remaining but I'd rather do the rest
of the cleanup in-tree so that it's easier to catch and revert
regressions.
I've dropped support for SSE1 (Firefox requires SSE2) and Altivec
(not wanting to deal with fixing Rust's Altivec support).
transform_neon.rs manually implements a bunch of intrinsics, this
can be fixed when we can depend on Rust 1.48.
The fuzz target is changed to a cargo-fuzz target.
Some of the gtests are moved to Rust.
