This is strictly a quality of life improvement when cross-compiling to
Windows targets. A common scenario is mounting an object directory
into a Windows VM, which requires additional VM configuration to
handle (absolute) symlinks. With this patch, `export NSDISTMODE=copy`
in a mozconfig sidesteps any such symlink issues.

This is just an awkward feature of the FasterMake build system:
without a direct consumer, GENERATED_FILES aren't handled. We
"consume" them into a dummy directory that isn't packaged. Sadly, the
FasterMake generic rule doesn't handle relative directories smoothly,
so we have to special case that too.

This one looks to be pretty straight-forward. It irritates me that
the jar.mn entry doesn't explicitly say that the result is coming from
the object directory, like
locale/browser/bookmarks.html (!bookmarks.html)
but that's for another day.

I don't understand how this will interact with the parts of the build
where we try to avoid installing the dist/bin manifest, but this makes
sense to me and it works locally for mobile/android and for browser/.

Now that XPT files are not loaded from files at runtime, code for
packaging XPT files can be removed.
This means that a couple of test XPIDL interfaces will get shipped in
builds to users that weren't before, but I don't think that matters
much.
This also puts XPT files into the local objdir for the XPIDL makefile,
instead of dist/bin, because they are no longer part of the
distribution.

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.

Recent changes in bug 1239217 added the faster backend to the default
build mechanism for artifact builds. This seems to have uncovered a
difference in behavior between GNU Make 3.81 and newer. Starting with
GNU Make 3.82, pattern rules are selected according to shortest stem.
Before, they are used in definition order.
So, we change the order of the pattern rules so the longest prefixes are
first. This should result in the same behavior on various GNU Make
implementations.

The FasterMake build system is meant to be invoked through `mach build
faster`, which does it already, or, in the near future, as part of an
hybrid build system, which will deal with it as well. People doing
`make -C objdir/faster` won't have the backend automatically refreshed,
but that's not a supported way to use it anyways.
Turns out the claim in bug 1234439 that the FasterMake backend knows
about all the chrome manifest entries is wrong, and there's still one
that is added "manually" with buildlist.py, and during mach build
faster, that can happen before or after the corresponding chrome
manifests are written out by install manifest processing.
While the real fix here would be to make the build system totally
aware of those "manifest interfaces.manifest" entries, for now, it's
simpler to add dependencies to work around the race condition.
MOZ_DEBUG_DEFINES are essentially defines used everywhere. So treat them as
feeding the initial value for DEFINES in each moz.build sandbox. This allows
the kind overrides that was done in the past by resetting MOZ_DEBUG_DEFINES
in Makefiles.
Bug 1191230 added override lines with # characters to chrome manifests
for Windows.
So far, chrome manifests were handled with buildlist.py like in the
RecursiveMake backend, fed with Make variables. Without proper quoting,
those Make variables are just truncated by Make on the first # character,
and this results in mach build faster failing because of that.
However, the reason why chrome manifests were handled with buildlist.py
originally is that not all chrome manifest entries were known to the
FasterMake backend, but they now all are.
So instead of relying on Make variables and buildlist.py, we can now
rely on the newly added install manifests feature allowing to create files
with a given content.
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 test I'm about to add doesn't have XPIDL files, and that currently avoids
the FasterMake backend to run properly. Also, in the future, when the FasterMake
grows the ability to build C++ files, it should be possible to build Spidermonkey
with the FasterMake backend, but it doesn't have XPIDL files either.
