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.
