Mostly removals, but also adding docs on how to create a
multilingual package right now.
I think I'd like to take another pass at those docs in a follow-up.

It becomes a library of some sort, so that multiple scripts can benefit
from it to build different versions of GCC.
The GPG key associated with GCC is also refreshed from keys.gnupg.net,
adding a new subkey, used to sign newer versions of GCC (and
postprocessed with pgpstrip to make it smaller).
We're soon going to build multiple versions of clang and gcc for linux,
and we need to differentiate them. Furthermore, there is a need for the
base-toolchains builds to use a fixed version of clang and gcc. So
rename the clang and gcc toolchain jobs to include their version, add
aliases to satisfy all existing jobs, and adjust the base-toolchains
jobs to use the explicit version.

Since bug 635961, building with relro makes elfhack try to use the bss
data for a temporary function pointer. If there is not enough space for
a pointer in the bss, elfhack will complain it couldn't find the bss.
In normal circumstances, this is most likely fine. Libraries with a bss
so small that it can't fit a pointer are already too small to be
elfhacked anyways. In Firefox, the two libraries with the smallest bss
have enough space for two pointers, and aren't elfhacked (libmozgtk.so
and libplds4.so).
However, the testcase that is used during the build to validate that
elfhack works doesn't have a large enough bss on x86-64, making elfhack
bail out, and the build fail as a consequence.
This, in turn, is due to the only non-thread-local zeroed data being an
int, which is not enough to fit a pointer on x86-64. We thus make it a
size_t.

Configure now detects VCS info. Configure now detects Watchman.
We can combine the two so configure can detect if Mercurial
is configured with Watchman enabled.
This commit does two things:
1) collects the Mercurial config so it is available to downstream checks
2) examines the config for presence and state of the fsmonitor
extension
We don't yet do anything with the fsmonitor state. But it should be
useful soon. Also, the return value is kinda wonky. This will almost
certainly be improved as soon as there is an actual consumer.

Often you only want to evaluate a function if all its dependencies
are true. Expressing this in a "when" can be difficult. So let's
add a convenience decorator for it.
The existing code for @depends_if() was refactored to take an
evaluation function as its first argument. This prevents some
duplicate code and turns @depends_if() and @depends_all() into
one-liners.

Build Stylo (the styling system from servo) by default in all
builds for win32, win64, macOS and linux64 targets. It was
previously enabled for automation builds, so this just changes
the behaviour for local developer builds.
Note that this introduces a new dependency on libclang for the
binding generator. If you're developing on a tier-1 platform,
run `./mach boostrap` to install a working copy. Otherwise
llvm+libclang 4.0.1 is recommended.
Remove the explicit --enable-stylo=build in mozconfig.stylo
in favour of the configure default.
Add mozconfig.stylo to the hazard and debug-asan mozconfigs
so LLVM_CONFIG is defined properly for those builds.
Based on a patch by Bobby Holly in bug 1356991.

In bug 1181040, we added ${var}_IS_SET variables for
mk_add_options-defined variables. In the two years since, that has never
been used for anything else than MOZ_PGO_IS_SET, and the only use for
that has now been removed, so remove those ${var}_IS_SET variables.

Note this will only enable it on try, autoland and mozilla-inbound,
which are the only branches where sccache are enabled at the moment.
Enabling on more builds (or not) is the subject of bug 1373460.
Also note that bug 1181040, that ensured PGO builds weren't using
sccache mentions that back then, link times went up when using sccache
(with -Z7) vs. without, but that was presumably with MSVC 2013. Try
suggests link times are the same using sccache now (still using -Z7,
pending bug 1318370).

We want most builds to be actually using sccache, so we include
mozconfig.cache from mozconfig.common. However, since the --with-ccache
configure option doesn't exist on non-compile jobs (e.g. artifact
builds), we move to using the CCACHE environment variable instead, which
allows us to unset it in mozconfig.no-compile.
And since mozconfig.no-compile is always included where no_sccache is
set, we can remove that variable.

Bug 1365859 introduced a dependency on the Visual Studio binary 'fxc'
to generate Shader bytecode. This was unavailable when compiling for
Windows on Linux as part of a MinGW build.
This commit adds a configure check for fxc, and also searches for
fxc2, which was written (https://github.com/tomrittervg/fxc2) to be
a tiny application that wraps D3DCompileFromFile and can produce
similar (but not exactly the same) output as fxc.
fxc2 is compiled using MinGW for Windows, and runs under wine, so
we need to check for wine also.
Finally, fxc outputs some include information fxc2 doesn't, so
we will just change that assert to not take effect.

The |mach try| implementation isn't really testing specific so figured while doing this refactor
anyway we could take the opportunity to move it to /tools. This renames the "autotry" module to
"syntax" as one of the 'selectors' under the newly created tryselect module.

This option was added ~decade ago; AFAICT from bug archaeology, the
option was added to prevent our servers from being overwhelmed.
Somewhere over the years, however, we obtained more capable servers and
the option disappeared from mozconfigs. It seems moderately unlikely
that we'll have a need for this option again, and we could reintroduce
this patch very easily in any event. Let's go ahead and remove it.
The values that we need to find in the registry can be inconsistent across
different installations, so we retrieve values from both views in our search
for a valid SDK. This also ensures this works for 32-bit and 64-bit python.
Mercurial installs on Windows often provide both a native hg.exe
and a hg shell script. This allows them to work from both Windows
and UNIX-like shells.
While the which Python package searches for .exe and other common
executable extensions on Windows automatically, it doesn't prefer
these results to an extension-less value. This meant that "hg"
was resolved to the shell script. When we went to run it, it
failed because it isn't a valid Win32 application.
We work around the problem by preferring "hg.exe" over "hg"
for the binary name.
Ideally this would be platform specific. But the harm should be
minimal.

For reasons unknown to me, Windows CI is periodically failing to find
the Mercurial binary.
In addition, we've also reimplemented various VCS logic throughout
the build system. There is room to cut down on code complexity by
e.g. recording VCS info in configure instead of determining it
at run-time.
Also, for forensic purposes it is sometimes desirable to know which
VCS tool is in use by a build and which version of that tool is being
used.
This commit adds VCS type detection, binary searching, and version
resolution to configure.
substs now contains VCS_CHECKOUT_TYPE, HG, and GIT, which can be
consulted by downstream consumers.
If the Mercurial or Git versions could not be resolved, all variables
are not set. Otherwise, VCS_CHECKOUT_TYPE and one of HG or GIT is set.
If MOZ_AUTOMATION is set, we require that the VCS info be resolved.
This helps prevents weirdness in automation due to unexpected
environment configuration.

developer_options (!--enable-release) implies to search for and prefer
the gold linker. As part of porting gold detection to moz.configure
in d0e782180741 (bug 1351109), the logic inadvertently changed to
require gold when either --enable-gold or !--enable-release were
present.
This commit relaxes the requirement to find gold when only --enable-gold
is true.

check_prog, when used with a `when` argument, doesn't work the same way
as putting it under a `with only_when()` block, while it should. The
difference comes from the fact that `with only_when()` applies the
`when` to every option and depends used in the block (which check_prog
calls a bunch of).
So, we "manually" apply the `when` to all option and depends in
check_prog. An alternative solution would be to put the whole function
under a `with only_when()` block, but that would mean reindenting the
whole function.
Either way, as a consequence, this requires the `when` to have a
dependency on --help for "non-trivial" functions, which fortunately,
there's only one of.

LLVM_CONFIG, per the contents of toolkit/moz.configure, is tied to
--enable-stylo, but it currently is set on all types of builds. It
currently happens to work, but it's actually not meant to, and sure
enough, the fix for bug 1374727 exacerbates that.
So we create a new mozconfig.stylo file that enables stylo and sets
LLVM_CONFIG, such that only build types that do enable stylo have
LLVM_CONFIG set.

This enables apm logging by setting the apm_debug_dump variable in gyp.mozbuild.
Prior to this change, some files were including apm_data_dumper.h with logging
enabled and some were not.
This also removes the AEC* C interface and calls into webrtc::Trace directly.
Whatever historical reasons for having a C interface into these calls no
longer seems to apply. In addition reserving a buffer for the base file name
and then ensuring it was null terminated caused an ASAN "stack-buffer-overflow"
while testing. This was because it was not handling an empty base file
name properly. This would not normally happen if AEC logging was enabled through
about:webrtc, but it still seems safer to use std::string.
