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
root Makefile.in. We can refactor this later. For now, let's
take the quick win.

This also fixes the issue of processing the artifacts twice in some
situations (bug 1275673). Note that the artifact download no longer
happens when a specific target is passed to 'mach build'.

On my i7-6700K time and size for the full zip archive for a Windows
debug build is as follows:
Time Size
Before: 25.4s 278,708,278
After: 13.0s 280,623,521
Anything lower than level 5 and the archive size starts increasing by
several megabytes. Level 5 is definitely the sweet spot.

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
dummy wrapper used by `mach build faster`, leading to `Nothing to be done
for install-dist_idl.`, subsequently failing to build xpt files because
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.
