For people working on Rust code, compiling in debug mode (Cargo's "dev"
profile) is convenient: debug assertions are turned on, optimization is
turned off, and parallel compilation inside of rustc itself can be
used. These things make the build faster and the debugging experience
more pleasant.
To obtain that currently, one needs to --enable-debug at the Gecko
toplevel, which turns on debug assertions for the entire browser, which
makes things run unreasonably slowly. So it would be desirable to be
able to turn *off* debug mode for the entirety of the browser, but turn
on debug mode for the Rust code only.
Hence this added switch, --enable-rust-debug, which does what it
suggests and defaults to the value of --enable-debug. For our own
sanity and because we judge it a non-existent use case, we do not
support --enable-debug --disable-rust-debug.

It is unfortunately not possible to include it last (or close to last,
before old.configure), but at least putting it after toolchain related
includes will be helpful.

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.

Previously, configure found nsis on PATH, likely from MozillaBuild.
In our msys2 environment, nsis is installed under /mingw32. We
supplement moz.configure to look for nsis in this location.

Nothing is using MAKE in old-configure, and it was not AC_SUBST'ed, so
we don't need to set it when it's not set in the environment already.

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.

Setting MOZ_DEBUG_SYMBOLS as a define was not moved, as this value is not
checked, and exporting MOZ_DEBUG_SYMBOLS was not moved, as this would only
impact nspr, and we're no longer using the nspr build system.

--enable-build-backend was taking a list of additional backends to add
to the defaults. Changes to allow to disable some of the defaults is not
possible in a straightforward way, so introduce a new
--build-backends option that sets the exact set of wanted backends,
but also allows to add and remove from the defaults with + or -.
--build-backends=+CompileDB is equivalent to
--enable-build-backend=CompileDB.
--build-backends=-VisualStudio disables the VS backend when it's
automatically enabled.
Now that the VisualStudio backend will no-op if nothing has changed, it
should be safe to always run this backend.
On first run, backend generation takes ~3.5s on my machine. On subsequent run,
it takes ~1.5s. Wall time for a no-op config.status is now ~15.7s. We could like
make the Visual Studio backend faster by not writing so many project files.
But this would require consolidating libraries in moz.build files. And that's
out of scope for this change.
We drop the check for MSVS_VERSION because it won't always be defined on
MinGW/GCC builds. We simply default to "2015" if it isn't set.

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.
