This patch introduces a small change in behavior: we now unconditionally
require libffi > 3.0.9 when using system ffi, rather than accepting 3.0.9
when using GCC, as 3.0.10 was released 5 years ago, and should be widely
available.

This required implementing a utility function to resolve the binary
type. I used GetBinaryTypeW via ctypes because this seems the fastest.
I arbitrarily limited the function to testing 32-bit and 64-bit Windows
executables because hopefully those are the only executables we'll
ever encounter. We can expand the binary detection later, if needed.
This includes support for running on non-Windows platforms.

We want to ensure that our automation builds don't pull in libraries
from crates.io, and we need --frozen support in cargo to do that. If we
don't have that support, we shouldn't build.
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 patch is really two separate changes.
The first change is that rust crates are large, standalone entities that
may contain multitudes of source files. It therefore doesn't make sense
to keep them in SOURCES, as we have been doing. Moving to use cargo
will require a higher-level approach, which suggests that we need a
different, higher-level representation for Rust sources in the build
system.
The representation here is to have the build system refer to things
defined in Cargo.toml files as the entities dealt with in the build
system, and let Cargo deal with the details of actually building things.
This approach means that adding a new crate to an existing library just
requires editing Rust and Cargo.toml files, rather than dealing with
moz.build, which seems more natural to Rust programmers. By having the
source files for libraries (and binaries in subsequent iterations of
this support) checked in to the tree, we can also take advantage of
Cargo.lock files.
The second is that we switch the core build system over to building via
cargo, rather than invoking rustc directly.
We also clean up a number of leftover things from the Old Way of doing
things. A number of tests are added to confirm that we'll only permit
crates to be built that have dependencies in-tree.
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.

Currently, it returns either None or the contents of the compiler's stdout,
which is always expected to be an empty string, and is not very useful. So
instead, return True in the latter case.

Now that check_prog, through find_program, returns paths that the build
system can handle, we don't need MT to just be "mt.exe".
However, we still need the PATH to be altered for the other tools we're
not checking in python configure yet (e.g. midl). We also still need
PATH altered for the compiler itself, because for e.g. the amd_x86
version, a necessary DLL is in the amd directory, which means PATH
always needs to be altered for cl.exe.
This is hopefully more reliable than parsing just the summary line,
and makes available other keys like the commit-hash which we'd like
to pass to the debug symbol automation.
Note that the commit-hash field will have the value 'unknown' for
builds not made out of upstream git. So the key is available with
official and gecko rust builds, but not for example the current
Debian-packaged rustc.

Before bug 1289294, the impossibility to find the version of MT was only
issuing a warning. Warnings in configure are essentially useless, so
since we weren't and still aren't doing anything with the result of that
check, and since there are versions of MT that don't print out a version
number, just remove the check.

Since bug 1264482, unknown CPU types end up triggering a ValueError
exception because of the CPU EnumString. Even if somehow the CPU is
valid, the endianness is not and would trigger a ValueError exception
as well.
So, instead of letting the exceptions happen, use a nicer failure mode
with an explicit die().

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.

Until now, it's not been possible to do something as straightforward as:
option('--foo', default=delayed_getattr(milestone, 'is_nightly'))
The reason is that option's default needs what it's given, if it's a
@depends function, to depend on --help.
But we can't have every delayed_getattr add dependencies on --help,
because that would make unwanted things to depend on --help and run
when displaying the help.
Until we can totally remove --help dependencies, this change makes the
resulting @depends function created by delayed_getattr depend on --help
if the @depends function it's given already depends on --help.
The mozconfig detection logic has bitten us on many occasions in the
past. The following changes are made to tentatively improve the
situation:
- The API is modified such that autodetection of the mozconfig has
to be a conscious decision made by the caller, and not triggered
any time there is no mozconfig given, which could be a conscious
decision of the opposite.
- mozinfo.json now stores the actual mozconfig (or lack thereof) used
during configure.

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

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.
For most cases, this replaces a value that was set in a way that would ignore
an environment variable, so this restores behavior for values that were
set in confvars.sh.

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, allow to enable jemalloc 4 with --enable-jemalloc=4.
MOZ_JEMALLOC4 will be deprecated later.
This also changes the semantics for freebsd, where the system jemalloc
is used, relying on MOZ_MEMORY being unset (default on freebsd) and
MOZ_JEMALLOC4 to be set. In this new setup, MOZ_JEMALLOC4 implies
--enable-jemalloc=4, which still works because of the corresponding
changes to old-configure.
While forgetting about it was warned about, having to add every new
environment option to wanted_mozconfig_variables is cumbersome. It turns
out there is a hackish way to make things work without that list, which,
all things considered, is not worse than the hacks around the
wanted_mozconfig_variables function, and are certainly an improvement as
it doesn't require an ever growing list of environment options.
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".
