Profiling revealed that mozpath.relpath() accounted for a lot of CPU
time when operating on an input of ~42,000 paths.
Due to the nature of the paths we're operating on, we don't need the
full power of mozpath.relpath() here. Instead, we can implement a
specialized version that works given already normalized paths and the
knowledge that context paths must be ancestors of the current path
being examined.
This change drops execution time of a mach command feeding ~42,000
paths to this function from ~90s to ~24s. On an input with 9131 paths,
execution time dropped from ~8.8s to ~3.7s.

Calling self.test_defaults_for_path() from files_info() with tens
of thousands of paths resulted in a CPU explosion in various path
normalization functions. I don't think it was so much the complexity
of the operations as much as the volume.
For an input with 9131 elements, this reduces execution time of a
mach command from ~25.7s to ~8.8s. With ~42,000 inputs, execution time
drops from <it took too long and I gave up> to ~90s.

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.

This commit moves symbol dumping to the compile tier, to be run via "syms"
targets. Tracking files are used for the sake of incremental builds, because
dump_syms may genearate multiple outputs whose paths are not known ahead of
time.
Minimal changes to symbolstore.py are made here. More extensive
simplifications will be made in a future commit on the basis of symbolstore.py
handling one file at a time.

This creates "syms" targets that depend on the corresponding "target" for
directories containing shared libraries or programs. These targets are added
to the main compile graph in automation, and can be invoked through a special
"symbols" target. A future commit will use these targets to dump symbols for
shared libraries and programs during the compile tier.

This is the initial support of 'mach repackage', which can take an
existing tarball and create a DMG on either an OSX host or on a Linux
host with cross-OSX tools. Configure is needed in order to find the
tools necessary to create the DMG. On a Linux cross-compiled environment
with tooltool, this can be as simple as:

In bug 1335309, FileFinder was made to default to not find executables,
and zip.py was made to use the default instead. Which made sense for
most uses of zip.py, except for the jsshell package.
So we add a flag to make zip.py able to strip executable (which happens
when the FileFinder is made to find them), and use that flag for the
jsshell package only.

EmptyConfig objects set JS_STANDALONE=1 by default. However, test tasks that need to run without an objdir
need to be behind an "if not CONFIG['JS_STANDALONE']" condition to avoid causing bustage to sm-pkg task (js
packaging). This patch explicitly deletes that default value, only when generating the TestManifestBackend.
Ideally, the js/src packaging should have their own moz.build instead of re-using the root moz.build. But this
is an easier fix in the short term to get the marionette-harness tests working again.

Because test_objects was a generator, using it in the condition always returned True,
even if no tests were found. But extending test_objects to the manifest, converts it
to a list. So this patch simply moves the 'no tests' check a bit later on.

This formats the marionette-harness python tests to be a regular |mach python-test| suite. Though
we add subsuite=marionette, this is just for automation purposes. The new preferred way to run the
marionette harness tests locally is:
./mach python-test testing/marionette
They will also run if running the full suite.
The mozbase packages.txt file modifies mozlog to use 'setup.py' instead of 'pth'. The reason for
this is that the marionette-harness tests use the pytest_mozlog pytest plugin for formatting
their results (converts pytest format into something resembling the standard tbpl logging format).
In order for this plugin to get picked up however, mozlog's setup.py file needs to be processed.

Cargo hashes various compilation settings into the dependency graph for
dependent libraries. So if the compilation settings for gkrust and
gkrust-gtest are different, their dependencies will likewise be
different. The setup we've created in the previous patches depends on
the compilation settings being identical, so we should enforce that at
the moz.build level.
Rust libraries can set RUST_LIBRARY_TARGET_DIR so that they can share
compilation artifacts with other libraries. This setting needs to be
propagated to the backend so it can be communicated to Cargo.

This removes the UNIFY_DIST and UNIFIED_BUILD variables, as well as the
--unify flag from the packager and UnifiedBuildFinder from mozpack. As a
result the STAGEPATH variable is never defined anymore, so its uses can
be removed as well.
test_unify.py is currently the only mozbuild/mozpack test that fails
without running configure first, and there isn't much point in fixing
tests for things that we don't actually use anymore.

This adds the ability to use manifestparser subsuites to |mach python-test|.
Subsuites are based on the premise of a "default" set that gets run when no
subsuites are explicitly specified. When a test is labelled with a subsuite,
that test is removed from the default set and will only run if that subsuite
is explicitly specified. This will allow us to chunk python unittests out of
'make check' piecemeal. The default set will run in 'make check', and
individual tasks (e.g mozbase), will specify a subsuite explicitly.
The |mach python-test| implementation is slightly different. By default,
subsuites are not considered if developers do not pass in --subsuite. This
means running |mach python-test| without arguments will still run the full set
of tests, and similarly, passing in test paths will *just work*.
If for some reason a developer needs to actually run the default set, a special
"default" subsuite has been create, so they can use
|mach python-test --subsuite default|. This default subsuite is also what 'make
check' will explicitly invoke.

This replaces the 'run-tests-deps' make target with a python function that will directly
read moz.build files, emit them with TestManifestEmitter, then consume them with
TestManifestBackend. Because the TestResolver is the only place that actually reads the
test metadata files, we can remove this logic from the CommonBackend as well.

Currently, the only way to emit objects after reading moz.build, is to emit everything. Though, sometimes
it may be desirable to only emit certain types of objects. This adds a new argument that allows consumers
to specify a custom emitter function. This gives them the flexibility to do whatever they want.
This will be used when resolving tests, so only TestManifest objects are emitted.

Currently the CommonBackend is responsible for processing TestManifest objects and using them to generate
the test metadata files (e.g all-tests.pkl et al). This patch pulls that logic out into a partial backend
specifically for test manifests.
This patch is solely a refactoring and shouldn't change any build behaviour. CommonBackend has a
TestManifestBackend instance and calls consume_object directly on it. However, this is just a temporary
measure to avoid checking in a broken commit.
This commit also adds a test for the 'test-defaults.pkl' file which was previously missing.

When vendoring third-party files, we'd like an explicit notice/review
when said files contain a "large file". This commit adds such checks
for files vendored via `mach vendor rust`.
As we don't yet have a server-side hook in place to prevent large files
from being added, we just have a command-line flag that people are
expected to use, on the honor system, to permit large files to be added
when vendoring.
This command is useful for users who wish to perform something like the
following:
1. Add/remove a bunch of files;
2. Examine the additions/removals/modifications for interesting changes;
3. Reject the add/remove if it doesn't meet some set of conditions.
The FileNotFoundError built-in exception is only present in
python 3. Emulate its behaviour in python 2 with a conditional
OSError.
