Because some older python 2.7 versions throw bogus errors when using the
exec statement as a function, use the function we added in bug 1264831
everywhere we use exec in the various configure tests. It doesn't take
much to trigger them, and the following changes ends up doing exactly
that.
Our current build system support for Rust compiles any Rust crate into a
so-called staticlib, which is a static library (.a file) that includes
the Rust runtime. That staticlib is then linked into libxul. For
supporting multiple crates, this approach breaks down, as linking
multiple copies of the Rust runtime is going to fail.
For supporting multiple crates, the approach taken here is to compile
each crate into a so-called rlib, which is essentially a staticlib
without the Rust runtime linked in. The build system takes note of
every crate destined for linking with libxul (treating them like static
libraries generated from C/C++ files), and generates a super-crate,
whimsically named "rul", that is compiled as a staticlib (so as to
include the Rust runtime) and then linked into libxul. Thus only one
copy of the Rust runtime is included, and the Rust compiler can take
care of any inter-crate dependencies.
This patch currently only supports Rust code in shared libraries, not in
binaries.
This accounts for default unittest and pytest output formatting,
in addition to mozunit.

The format provided to the build system by the manifest parser is highly redundant:
every test lists all variables for that test, and many tests use a large
support-files entry in DEFAULT that ends up in individual test objects. This
patch stores these DEFAULTS per-manifest rather than per-test to save disk
space, resulting in about a ~22mb smaller all-tests.json file. The
in-memory representation of tests is not changed by this patch, as the defaults
are again propagated to individual tests as all-tests.json is read by the test
resolver.

imply_option has no effect when the resolved value is None, so the same
logic can be applied when checking for unknown implied options.
This allows to imply options that may not always exist (because they are
in a configure file that is optionally included).
Ideally, it would be better not to do this, but until we have something
better than optionally included configure files for
--disable-compile-environment, this is a necessary evil.
So far, everything was essentially executed at "declaration". This
made the sandbox code simpler, but to improve on the tooling around
python configure (for tests and introspection), we need to have more
flexibility, which executing everything at declaration doesn't give.
With this change, only @depends functions depending on --help, as
well as templates, are executed at the moment the moz.configure
files are included in the sandbox. The remainder is executed at the
end.

Whether it uses locale._parse_localename or nl_langinfo makes it have completely
different results in weird and/or widespread locale settings (LC_ALL=UTF-8 or
LC_ALL=C).
