Warn about possible misuse of the comma operator such as between two statements or to call a function for side effects within an expression. Only enable these -Wcomma warnings for C++ code because there are almost two hundred -Wcomma warnings in third-party C libraries. I reviewed the C warnings and confirmed none of them were latent bugs. We won't fix these libraries' warnings so they are just noise.

I've moved the mozilla specific gtest stuff to link directly in xul-gtest
rather than in the gtest static library to make it possible for standalone
programs to link against this library and not have to link
against other mozilla libraries. This allows us to build
media/webrtc/signaling/fuzztest against this version of gtest rather than the
webrtc version of gtest, which I plan to remove in a follow on bug.
I had to add a global disable for -Wgnu-zero-variadic-macro-arguments as we
hit that everywhere we use the INSTANTIATE_TEST_CASE_P macro.
This brings forward the fix from Bug 844630 to the visibility of environ in
gtest-death-test.cc.
I also removed code that set GTEST_API_ to a visibility that conflicts with
what we've defined elsewhere in tree.

Currently mozconfig.cache overrides a few build options for sccache. This
patch moves them into toolchain.configure so that the build system will
set them properly when sccache is in use. Additionally, {CC,CXX}_WRAPPER
are set in config.mk, so just avoid setting them when sccache is in use.

This is primarily motivated by webrender and the audio remoting

We want to avoid giving --help dependencies to host and target, so that
they we don't spawn config.guess and config.sub when running configure
--help, and don't need to reach out to the which module to find a
suitable shell to execute them.
So, when --help is given, we return a fake host/target namespace, and
avoid the config.guess/config.sub-invoking code being executed.
Then, by giving the --help option to the linter, it can properly find
that the config.guess/config.sub-invoking code doesn't need the
dependency on --help.
This effectively unbreaks configure --help after bug 1313306.

It turns out that running makecab to compress PDB files takes a significant
amount of time in the buildsymbols step. I wrote an implementation of
makecab in Rust that implements only the subset of features we use and
it's significantly faster:
https://github.com/luser/rust-makecab
This patch adds a makecab check to moz.configure, adds a release build of
the makecab binary to the Windows tooltool manifests, points the build at
it from mozconfig.win-common, and changes symbolstore.py to use MAKECAB
from substs instead of calling `makecab.exe` directly.

It turns out that, in practice, the LD variable is not used by the build

This patch does a few things:
1) Change all the in-tree tooltool manifests to contain sccache2 instead of the existing Python sccache
2) Change mozconfig.cache to point at sccache.
3) Lightly tweak the --with-cccache configure option to support sccache, and detect whether we're using ccache or sccache and set an option appropriately.
4) Add a MOZ_SCCACHE_VERBOSE_STATS option, and add a target in the top-level Makefile to make sccache spit out its stats at the end of the build. This is useful to see the cache hits/errors until we get something better.
5) Add MOZ_USING_SCCACHE to the build telemetry. Not that I think it will be immediately useful, but for future use.

This patch contains a number of changes to the gyp_reader code:
* Add three new flags to GYP_DIRS:
** no_chromium, to skip forcing the includes/etc needed for chromium gyp files
** no_unified, to force building all sources without unification
** action_overrides, to pass scripts used when mapping gyp actions to moz.build GENERATED_FILES
* Handle the flags mentioned above in read_from_gyp
* Handle actions in gyp targets by mapping them to GENERATED_FILES, using scripts specified in the action_overrides flag. We don't try to handle the generic action case, we require special-casing for each action.
* Handle a subset of copies in gyp targets by mapping them to EXPORTS, just enough to handle the use of them for NSS exports.
* Handle shared_library and executable gyp targets
* Handle gyp target dependencies/libraries as USE_LIBS/OS_LIBS
* Handle generated source files
* Handle .def files in sources by mapping them to SYMBOLS_FILE
* Special-case some include_dirs:
** Map `<(PRODUCT_DIR)/dist/` to $DIST/include (to handle include paths for NSS exports)
** Map include_dirs starting with topobjdir to objdir-relative paths, to handle passing the NSPR include path to NSS
* split /build/gyp.mozbuild into two parts, with gyp_base.mozbuild containing generic bits, and gyp.mozbuild containing chromium-specific bits

GCC and Clang will colorize compiler output automatically if stdout is a
TTY. Unfortunately, when the build backend is invoked via `mach`,
stdout is not a TTY.
6e9a4c0b9cd8 (bug 1315785) changed mach so it exports an environment
variable indicating whether mach's original stdout is a TTY. This was
later used to add color flags to `cargo` invocations.
Building on that work, this patch adds color flags to compiler
invocations if the compiler supports color and a mach TTY is
detected. The result is that compiler output from `mach build`
will be colorized automatically if Clang or a modern version of
GCC is used.
The only issue I see with this is that Clang doesn't "unset" its color
sequences when printing a newline. As a result, mach's time line
prefixing can sometimes inherit "bold" or other stylings. AFAICT this is
only a minor cosmetic concern. GCC does not exhibit this issue.

Importing 'os' in python configure functions, on Windows, changes the
separate the various os.path functions use, and that can have
unexpected, badly handled, consequences. While on the long term, it is
desirable to make @imports('os') modify os.path to use the same base
functions as if there were no @imports, let's go with the simpler
workaround of restoring the non-{isfile,isdir,exists} os.path functions
from b6be0e9e3e1e.

The toolchain checks are now such that we can stop special casing x86-64
<-> x86 cross compiling. OTOH, depending on the target, the toolchain
prefix can be of the form `cpu-os` or `cpu-machine-os`. We were only
using the former, and we change this to allow to try both.
Finally, the toolchain prefix being a gcc thing, it applies on all
target platforms where we try to use gcc.
However, the status quo is kept for the value of TOOLCHAIN_PREFIX
exposed to old-configure and the build system, until the various tools
paths (such as ar, readelf, etc.) are handled in python configure.
