Ubuntu 20.04 does not have libudev-dev causing build
failure when compiling libudev-sys, which is in-turn
needed by gilrs-core. Similarly, nix build also needs
the udev C library.
On Ubuntu 22.04, we don't see the build failures since
the build dependency 'libgstreamer-plugins-base-1.0-dev'
transitively pulls in libudev-dev.

1. First check to see if a package is available before trying to install
it. This means that we always do our best to install everything, but
don't fail if we cannot.
2. Install crown and taplo first. This means that if the
platform-specific bits fail, we still install Servo-specific
dependencies.
This fixes an issue where the dylib for harfbuzz cannot be found when
running unit tests on some systems, because unit tests don't get their
rpaths adjusted during build. This is quite likely an issue with dylib
dependency management. We just need a bit more exploration of how this
is traditionally handled.
Ubuntu 20.04 doesn't have a new enough version of GStreamer, so
automatically disable media when running on that platform.
This also cleans up the media detection a bit, putting the result in a
`enable-media` variable and moving some of the logic into the build
scripts themselves rather than the platform module.
- Upgrade the version of GStreamer for Windows
This upgrades the Windows build to use the most recent version of
GStreamer. This is necessary to upgrade our GStreamer dependency.
- Stop shipping GStreamer binaries on Linux
The binary bundle of GStreamer that we package is not used to compile --
only to run layout tests. It's too old for the APIs that we are using
(as evidenced by needed 1.18 for WebRTC) and nowadays Linux
distributions carry a new version so it's unecessary for our build
machines. No longer using this binary bundle will allow us to upgrade
our GStreamer dependency -- which now has stricter checks that we
are using at least version 1.18.
- Upgrade media to use newer versions of GStreamer / GLib dependencies
This completes the transition to compiling Servo with rust stable. Some
nightly-only features are still used when compiling the `script` and
`crown` crates, as well as for some style unit tests. These will likely
break with newer compiler versions, but `crown` can be disabled for them
conditionally. This is just the first step.
This has some caveats:
1. We need to disable setting up the special linker on Linux. The -Z
option isn't supported with stable rust so using this is out --
meanwhile we can't be sure that lld is installed on most systems.
2. `cargo fmt` still uses some unstable options, so we need to rely on
the unstable toolchain just for running `fmt`. The idea is to fix this
gradually.
* Update mozjs
* moztools4 in bootstrap
* no autoconf
* tidy
* switch to servo-build-deps
* update mozjs for real
* glue mozjs
* fmt
* move to servo/mozjs
The -Zgcc-ld=lld flag makes rust use the rust-lld
linker that is distributed as part of rust toolchain.
However, this flag doesn't work on nixos correctly
as
1) rust-lld needs to be patched to have the correct rpath
to find libz.so
2) the bin/gcc-ld/ld.lld wrapper which calls rust-lld also
needs to be patched to use the correct dynamic loader
3) rust-lld doesn't respect NIX_LDFLAGS which contains
the additional search path derived from buildInputs.
The system linkers on nixos are wrapped so that
NIX_LDFLAGS is added as the rpath to the final binary.

This change replaces OpenSSL with rustls and also the manually curated
CA certs file with webpki-roots (effectively the same thing, but as a
crate).
Generally speaking the design of the network stack is the same. Changes:
- Code around certificate overrides needed to be refactored to work with
rustls so the various thread-safe list of certificates is refactored
into `CertificateErrorOverrideManager`
- hyper-rustls takes care of setting ALPN protocols for HTTP requests,
so for WebSockets this is moved to the WebSocket code.
- The safe set of cypher suites is chosen, which seem to correspond to
the "Modern" configuration from [1]. This can be adjusted later.
- Instead of passing a string of PEM CA certificates around, an enum is
used that includes parsed Certificates (or the default which reads
them from webpki-roots).
- Code for starting up an SSL server for testing is cleaned up a little,
due to the fact that the certificates need to be overriden explicitly
now. This is due to the fact that the `webpki` crate is more stringent
with self-signed certificates than SSL (CA certificates cannot used as
end-entity certificates). [2]

- os.environ is always `str` in Python 3.
- The only string type is `str` so we can stop using `six.str_types`.
- `iteritems()` isn't necessary because dicts have the `items()` method.
This change makes it so that the Platform classes can now handle
installing GStreamer dependencies and properly setting up the
environment including when cross-compiling. For Windows and Linux
is now installed into `target/dependencies/gstreamer` when not installed
system-wide. In addition:
1. Creating and moving existing environment path append helpers to
`util.py`.
2. Combining the `set_run_env` and `build_dev` functions and moving
some outside code into them so that it can be shared. Now code that
used to call `set_run_env` calls `build_dev` and then
`os.environ.update(...)`.
3. Adding Python typing information in many places.
