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.

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.

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.

Some compilers on some platforms by default #define some of the values
we're using in the source we use in get_compiler_info(). Namely,
mingw-gcc #defines WINNT by default, and the WINNT in the source is then
replaced by 1, breaking the check.
The C preprocessor, fortunately, doesn't expand macros inside C strings.
So instead of `%KERNEL WINNT`, we output `%KERNEL "WINNT"`, and strip
out the double quotes. For good measure, we do this for all values in
the source used in get_compiler_info().

clang-cl, oddly, does not accept -g and wants the MSVC-esque -Zi
option instead.

Until now, HAVE_64BIT_BUILD was entirely determined by a compiler check.
But we didn't run the check on e.g. artifact builds, while relying on
its result for some non-compilation related things, leading to subtle
discrepancies.
This changes the configure check to derive HAVE_64BIT_BUILD from bitness
determined by the target CPU, and double checked with a compiler check.

Also, now that we're using modern C++11 compilers, we can just rely on
static_assert, instead of the pile of macros used in the autoconf test.

The base compiler check in python configure does some preprocessing,
which ensures the compiler works to some extent. Autoconf used to have
a more complete test, doing a compile/link. We do have plenty of tests
afterwards that do that anyways, but it's better if we fail early if
the toolchain fails somehow.
This refactors try_compile such that the *_compiler variable themselves
can be used to trigger compiler tests. Eventually, we'll want something
similar for preprocessing and possibly other invocations.
This also removes similar tests from build/autoconf/toolchain.m4.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

Per froydnj in bug 1186064 comment #23, "it makes sense to proceed with removing
MSVC 2013 support." This commit does that.
We also go a step further and require VS2015 Update 2 instead of just
update 1. This temporarily brings us down to just 1 officially supported
Visual Studio version. However, VS2015u3 was just released and is
unofficially supported.
Since MOZ_CRT is no longer set, references to it have been removed.

checked, and exporting MOZ_DEBUG_SYMBOLS was not moved, as this would only

This patch adds support for configuring Gonk/B2G with Android-specific
build scripts. This removes duplicated code and simplifies maintenance
of B2G.
The B2G builds will now use libc++ for Gecko; instead of the obsolete
STLport. A side-effect of this patch is the removal of any compile-time
dependency on B2G's bionic library.

Before bug 1269513, yasm_version returned a Version object, and it
doesn't anymore, which made the assignment of _YASM_*_VERSION skipped
silently.
Then, configure would go through the yasm version checks as if they were
false and skipping over the AC_MSG_ERRORs, printing out:
/builds/slave/try-m64-0000000000000000000000/build/src/old-configure: line 19615: test: : integer expression expected
which is why this went undetected: the version checks were simply
ignored.
Some shells, however, evaluated the yasm version checks as true, hitting
the AC_MSG_ERRORs.
We no longer support MacOS X versions 10.6-10.8. Bumping the
default MACOSX_DEPLOYMENT_TARGET to 10.7 lets us start landing
changes which are incompatible with earlier SDKs.
Currently we build on 10.7, so moving to 10.9 must wait until
our infrastructure is reconfigured to run build jobs on more
recent MacOS versions.

We were unconditionally adding them, now actually check what the
compilers default to and add the flags if they are necessary.
This will, in the future, allow finer grained policy changes, where
we can decide that C++11 and C++14 are fine, downgrading compilers
that do C++17, etc.
At the same time, we improve things slightly by deriving HOST_CC from CC
in a smarter way, as well as CXX from CC, which we weren't doing
previously.
Many related things are not moved at the same time to keep the patch
somehow "small".
Gonk, Android, and the generic cross-compilation setup all were using a
different yet similar way to prefix the toolchain. The latter was even
wrong, since the target and target alias usually don't match actual
toolchain prefixes (which don't include the machine part of the target).
The reason the "checking" string always appears is that @depends
functions are always called, regardless of the value of the dependency.
This introduces a new decorator @depends_true, which works like
@depends, but the decorated function is not called unless one of the
dependency value resolves to True.
The new decorator can also be used to replace many cases where we do
@depends(foo)
def bar(foo):
if foo:
...
