This change makes us upload an `$(PKG_BASENAME).generated-files.tar.gz` archive
alongside other build artifacts which contains all the generated source files
from the build. A change after this will introduce an `upload-generated-sources`
task to take this artifact and upload the individual files to an S3 bucket.
This will be used to provide links to generated source files when they appear
in stack traces in crash reports.

Note this will only enable it on try, autoland and mozilla-inbound,
which are the only branches where sccache are enabled at the moment.
Enabling on more builds (or not) is the subject of bug 1373460.
Also note that bug 1181040, that ensured PGO builds weren't using
sccache mentions that back then, link times went up when using sccache
(with -Z7) vs. without, but that was presumably with MSVC 2013. Try
suggests link times are the same using sccache now (still using -Z7,
pending bug 1318370).

When investigating why a particular build got a particularly high number
of cache misses, it is useful to know exactly *what* had cache misses,
and you can't get the missing information after the fact.
We used to have some stats stored in a log file uploaded as artifact
with the old python sccache per bug 1005495 (and before that inline in
the build log), and we actually still have remains of that in the form
of a EXTRA_UPLOAD_FILES in build/mozconfig.cache.
Let's reuse that, and get some useful logs from sccache. Ideally sccache
would give better logs, but those are sufficient for now. We'll figure
things out eventually. https://github.com/mozilla/sccache/issues/151

This commit makes sccache dump JSON stats at the end of the build, and then
reads them in `BuildScript.generate_build_stats` and adds them to the
build_metrics we submit to Perfherder. The stats dumping is done in
Makefile.in where we currently dump verbose sccache stats because sccache
doesn't persist stats to disk right now and it will also shut down its server
process after 5 minutes, so when the post-build automation steps take more
than 5 minutes the server shuts down and the stats are lost.
Currently it's collecting:
* Cache hit rate
* Cache write errors
* Non-cacheable requests (compiler invocations that sccache can't cache)
We can always grow this list later.

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 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 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.

In bug 1320194 we want to generate a TestManifest backend without first
invoking configure. However, we still need a way to update the backend,
which is normally handled by the top-level Makefile. We can split this
logic out into a separate file, rebuild-backend.mk, which can be invoked
directly as long as the appropriate environment variables are set
(BUILD_BACKEND_FILES, BACKEND_GENERATION_SCRIPT, and PYTHON).

This patch does a few things:
1) Change all the in-tree tooltool manifests to contain sccache2 instead of the existing Python sccache
2) Change mozconfig.cache to point at sccache.
3) Lightly tweak the --with-cccache configure option to support sccache, and detect whether we're using ccache or sccache and set an option appropriately.
4) Add a MOZ_SCCACHE_VERBOSE_STATS option, and add a target in the top-level Makefile to make sccache spit out its stats at the end of the build. This is useful to see the cache hits/errors until we get something better.
5) Add MOZ_USING_SCCACHE to the build telemetry. Not that I think it will be immediately useful, but for future use.

Each archive takes 10+ seconds to generate. Split the archiving
part into separate make targets so this completes faster.
I'm not super thrilled about adding yet more make targets to the

This moves test installation for test files out of the monolithic install
manifest for $objdir/_tests, and determines the test and support files
to install based on the object derived from all-tests.json. Additionally,
the files resulting from TEST_HARNESS_FILES are installed, as some tests
will depend on them.
As a result, the time to install tests when invoking the test runner will
scale with the number of tests requested to run rather than the entire set
of tests in the tree, resulting in significantly less overhead.

The behavior is not entirely idempotent (most notably for
buildconfig.html), but this can be improved later if necessary.
It is idempotent where it matters.
This allows to get rid of config/makefiles/rcs.mk and its uses.
FasterMake needs some RecursiveMake install manifests to have been
processed before doing its work, so we can actually end up processing
them twice because of the going back and forth from FasterMake in the
hybrid build system.
Set the dependency at the RecursiveMake level when doing an hybrid
build.

For some reason, recent changes with the install-dist/% rules broke the

of the missing idls in dist/idl.

The current rule is only for "backend.RecursiveMakeBackend", but, with
the current default of generating both the RecursiveMake and FasterMake
backends, the command creates/refreshes both backends. This is, in fact,
how the FasterMake backend is refreshed in most cases.
Moreover, with an hybrid backends, the generated file is not
"backend.RecursiveMakeBackend" anymore, so we need a more generic way to
handle this.
Furthermore, it's not necessarily desirable for all backends to have a
dependency file to handle the dependencies to refresh the backend, so
generate a plain list instead. This has the side effect of making `mach
build-backend --diff` more readable for changes to that file.
Finally, make the backend.* files created like any other backend file,
such that its diff appears in the `mach build-backend --diff` output.
Install manifests are not empty in normal conditions, apart a few
exceptions where they are only used for a "magic" `rm -rf`.
However, we're going to introduce changes that will empty some of
the install manifests and make their work happen from a different
backend, in which case we don't want them to correspond to a `rm -rf`.
While it would be possible to move those things in the export tier, it
is still interesting to have reporting for them separately, especially
considering I expect things to gradually move from the other tiers to
this new one.
While not entirely obvious, the recurse_pre-export target doesn't imply
actual recursion as long as the RecursiveMake backend doesn't emit
traversal information for it, so nothing will actually happen on this
target, but the interesting part is that it runs, per the generic
config/recurse.mk rules for tiers, between BUILDSTATUS TIER_START and
BUILDSTATUS TIER_FINISH, so that all its dependencies are accounted
as being part of the pre-export tier.
This change allows specifying objdir-relative paths in EXPORTS to enable
exporting entries from GENERATED_FILES. Objdir paths in EXPORTS that are
not in GENERATED_FILES will raise an exception.
Example:
```
EXPORTS += ['!g.h', 'f.h']
GENERATED_FILES += ['g.h']
```
Given the implementation, this should also work for FINAL_TARGET_FILES,
FINAL_TARGET_PP_FILES, and TESTING_FILES, but those are not well-tested.
This patch also renames the install manifest for '_tests' to match the
directory name for convenience in some code I refactored.

We have many unit tests in the tree for some small parts of the build system
pipeline, but we don't have anything that resembles an end to end test, and we
kind of rely on the resulting Firefox not being broken by our changes.
With the Faster make backend growing, I want to ensure it produces the same
thing as the recursive make backend, at least for the parts it supports.
This adds some kind of test that allows to check that.
The configure option has explicitly thrown an error for more than a year now,
and it happens that the remaining way to still forcefully use it has been
broken for more than 8 months.
This change merges mozilla-central and comm-central into having a single
topobjdir file but retaining two topsrcdirs (and two build systems). This state
is hopefully only the first part of a series of changes that eliminate the
comm-central build system partial clone completely.

Before making top-level traverse js/src moz.build files, there was a need to
distinguish between top-level traversing e.g. top-level moz.build or
config/moz.build and js/src traversing them. With a single traversal of both
moz.build sets, we now only need to distinguish between js standalone builds
and gecko builds.
There is still, however, a need to distinguish between top-level vs. js/src
configure runs on gecko builds to make them subconfigure icu and libffi from
top-level instead of js/src in js standalone builds, or when choosing to make
js/src's config.status do something when run or not.
Before, we would run configure in both top-level and js/src, and both
configures would traverse their own set of moz.builds, without actual
knowledge about the other. With this change, both configures still run,
but only top-level traverses moz.build files, and uses js/src's
config.status when traversing its moz.build files. This allows a better
sharing of information between both build systems and the removal of many
hacks.
This also moves running libffi and icu configure to top-level.
Standalone js builds still have their own configure doing moz.build traversal,
as before.

Before, we checked if config.status was stale in any entrant Makefile
(top level or child directory). This had undesirable side-effects for
partial tree builds, notably that if the build backend was out of date,
the current Makefile was invalidated.
With this patch, we only regenerate the build config automatically in
full/toplevel builds. If an outdated build config is detected on partial
tree builds, we error. The impact of this is mitigated by having mach
build automatically ensure the build config is current.

The existing tier traversal logic is only used in the top-level Makefile
but was present in rules.mk. This meant it was getting evaluated for
every Makefile. This was silly and thus the logic has mostly been moved into
its own .mk file and is only included for the root Makefile.
One of the first actions an invoked Makefile now does is check to see if
*any* moz.build file or Makefile.in is out of date. If so, config.status
is executed to rebuild the build backend.
Since we always perform this check as part of a build, we no longer need
special handling for out of date moz.build files during traversals. This
results in the removal of a significant amount of code!
Another upside of the change is that if a moz.build file is modified
during building, we don't (potentially) modify the build backend from
under the in-progress build. Thus the only race condition that remains
is if a moz.build is mutated during moz.build reading. This window (a
few seconds) is significantly shorter than the time of a full build
(minutes).
This patch should also enable us to remove empty Makefile.in files
without requiring a clobber.
