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.

Combined with the previous patch that sets MACH_STDOUT_ISATTY, the
practical effect of this patch is that cargo is invoked with
`--color=always` when mach was attached to a TTY and colorized output
is sent to the terminal.
Note: this doesn't work with Rust/Cargo 1.10 for reasons unknown to me.
It appears there was a bug with Rust/Cargo because `--color=never` still
sent colorized output on that version! Cargo/Rust 1.12.1 works fine.

In our current Rust world, we have the following dependency structure:
xul.so --------------------------+
|
xul-gtest.so -+--> xul.a --------+-> gkrust
|
+--> gkrust-gtest
This structure results in link errors with multiply-defined symbols
between gkrust-gtest and gkrust with newer Rust releases when linking
xul-gtest.so. So we have to do something different.
Our new structure is:
xul.so --------------------------+
|
xul-gtest.so -+--> xul.a --------+-> gkrust --+-> gkrust-shared
| |
+--> gkrust-gtest --------------+
and we enforce that a given shared library can only have at most one
Rust library that it depends on. Said Rust library is assumed to
include all significant Rust dependencies of the dependent static
libraries as well. (In the above structure, gkrust is simply a wrapper
around gkrust-shared, so gkrust-gtest doesn't have to include gkrust as
a dependency.)
To validate the PSSH init data passed to EME, I'd like to reuse the same
PSSH parser that the ClearKey CDM shared library uses. So move the code
out of gmp-clearkey and into its own library, so we can link it statically
into code that needs to use it.

This patch removes the memory usage tracking in the script that wraps the
linking of the xul library. This patch also generalizes the wrapping of the
xul linking process to all platforms.

Currently make check loops over all directories and runs each test file in PYTHON_UNIT_TESTS
individually. This patch instead creates a single top-level check target that runs
|mach python-tests|. This should make automation more similar to running locally, be a bit
quicker and make it easier to pull python tests out of make check completely at a future date.

This is relevant when attempting to build libffi with our build system
(libffi expects its assembly sources to be pre-processed).
