We are going to compile JS into WebAssembly! This is the first patch
in an upcoming queue. Here we introduce wasm32 architecture so that
SpiderMonkey can be compiled with enabled jit for wasi target.

Change XUL and other dylibs to be built with an @rpath/<dylib> install name (LC_ID_DYLIB) instead of @executable_path/<dylib>.
Change executables to be built with an @rpath dyld search path set to @executable_path by default so that @rpath/<dylib> dylibs in the same directory can be resolved. For executables not in the same directory as @rpath dylibs, such as plugin-container, set a relative @rpath such as @executable_path/../../../.
Previously, dylib install names were set as @executable_path/<dylib> allowing them to be resolved by dyld for the loading executable if the executable resided in the same directory as the dylib. For executables not in the same directory as the dylibs, dyld resolved these dylibs using DYLD_LIBRARY_PATH set before launching the process by Firefox code. With this change, loading does not rely on DYLD environment variables. Instead, dylibs have an install name set as @rpath/<dylib> and each executable loading a dylib has its @rpath set at compile-time to refer to dylib directory.

This addresses the original intent of the bug report which asks for allowing
sndio to be built on more than just OpenBSD. In addition of modifying the
existing --enable-sndio to support this request, the option
--enable-audio-backends was added which takes a list of possible backends to
support per discussion in the bug report.
For example specifying --enable-audio-backends=alsa,jack,pulseaudio,sndio
allows for runtime selection of those four cubeb backends. If all four backends
are available the user can specify `media.cubeb.backend` in `about:config` to
force a specific backend.
Removed superfluous set_define()s as libcubeb's moz.build does the necessary
`DEFINES['...']` assignments for each backend.
In addition logic for finer control of audio backend selection on Android was
added. One can now specify aaudio, opensl or both (which is the default).

Basically, argument types must allow for templated types and optional
args must recognize at least `mozilla::Nothing()`. It's a bit hacky but
it seems like a useful extension that won't destroy anything, and I
need this.

As mentioned in bug 1747354, the location of the dist directory is
relied to be $topobjdir/dist, so just use that consistently rather
than getting it from a separate variable for rust build scripts.

Goal of this patch is to allow disabling all JIT codegen in certain Firefox processes
to let us enable more security mitigations. The JS VM uses the atomic operation stubs
we compile at runtime so this patch converts those to inline assembly instead.
This adds a Python script to generate a header file that has all the inline assembly code.
The inline assembly instructions are based on the JIT-compiled trampoline code.
The generated header is used for all x86/x64/arm32/arm64 builds, so this now includes
no-JIT builds as well.

While mingw builds don't require user32 and advapi32 explicitly, it doesn't
hurt for them to be there (and they're required for clang-cl build).
Likewise, while clang-builds don't require uuid and userenv explicitly
because they're pulled in via #pragmas in the source code, mingw doesn't
support those #pragmas and needs them explicitly, which doesn't hurt the
clang-cl builds.

Also update the table of Firefox requirements. It's worth noting that I
actually upgraded to 1.57 earlier than I should have (too close to
freeze), but what is done is done.

It is the default. It has been the default since at least Xcode 2.2,
from 2005. ld64 doesn't say anything, but lld warns about it.
