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.

--enable-approximate-location and --enable-gps-debug were removed in bug
1278410.
--enable-media-navigator was removed in bug 1259581.
--enable-webapp-runtime was removed in bug 1238079.
Update the code generator and related classes in annotation processor to
use the new WrapForJNI flags. Also add some more sanity checking to make
sure the flags are used correctly.
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.
We need to rebuild clang with libc++ to get compatible headers for cross
builds. libc++abi is a dependency of libc++, as the build instructions
says [0].

It has not been useful since we removed the possibility to build in the
source directory.

Since bug 1259382, CC and CXX are always set, so we can stop
falling back to cl on Windows, and clang on OSX in compiler-opts.m4.
Also, we were actively rejecting GCC on OSX because it was based on
GCC 4.2 and known to be broken, but that test predates our requirement
for more recent versions of GCC, which would fail configure anyways.
So just remove that GCC test. Building with a modern GCC from macports
or wherever might actually work anyways.
Finally, remove target bit-width mismatch with the compiler as it's
handled in python configure since bug 1288313.
