Add .rs as a recognized file extension in SOURCES.
Propagate that through to the Makefile backend and add a dependency
generated and an explicit rule to call $(RUSTC) to compile them.
rustc builds static libraries, not obj files. At least, if one
asks it to output an obj file, I'm not clear how to get all the
compiler-specific runtime libraries the code will expect to link
to. Therefore we generate a static library for each rust source
file (which must be a complete crate for the time being) and link
that. Because of the extension it ends up on the LIBS line in the
the corresponding .desc file.
Note that the static library does still depend on some system
libraries, e.g. -ldl -lpthread -lm on linux. Gecko already
links to all of those, so we don't keep track of it here.
Should we need to add explicit linkage for other targets,
rustc does print a list to stderr which can be parsed.

Without this, invoking Make in a sub-directory will fail with an error
that libs:: cannot find target `target'.
Without this patch, the Fennec Gradle and IDE build integration fails
compiling its custom targets in mobile/android/base and

Now that moz.build can see EXTRA_*COMPONENTS and NO_JS_MANIFEST, we can
move some logic from rules.mk (executed every build) to moz.build's
emitter.py (executed only at build-backend time).
These definitions appear to have been added to support generating Java
interfaces from xpidl interface files. Since we don't support doing
that anymore, we don't need these definitions, either.
The recursivemake backend sets IMPORT_LIBRARY to the same value as
SHARED_LIBRARY on non-Windows platforms, so we can simply use
IMPORT_LIBRARY everywhere.
NO_INSTALL_IMPORT_LIBRARY is only used in one place, and since we don't even
use $(DIST)/lib for gecko, it actually doesn't make a difference presently.
We want the ability to read data from any moz.build file without needing
a full build configuration (running configure). This will enable tools
to consume metadata by merely having a copy of the source code and
nothing more.
This commit creates the EmptyConfig object. It is a config object that -
as its name implies - is empty. It will be used for reading moz.build
files in "no config" mode.
Many moz.build files make assumptions that variables in CONFIG are
defined and that they are strings. We create the EmptyValue type that
behaves like an empty unicode string. Since moz.build files also do some
type checking, we carve an exemption for EmptyValue, just like we do for
None.
We add a test to verify that reading moz.build files in "no config" mode
works. This required some minor changes to existing moz.build files to
make them work in the new execution mode.

moz.build files should execute in filesystem traversal mode. Add a test
that verifies this is true.
This test performs a brute force filesystem scan to find relevant
moz.build files. This can be a little slow. That's unfortunate. But it's
a price we need to pay in order to ensure metadata extraction mode
continues to work.

xpt files don't have a dependency on backend files to avoid rebuilding all
of them when adding or removing new files. On incremental builds, some kind
of dependencies are required to ensure the xpt files are refreshed when
adding or removing new idls.
Generating the list of idl deps to generate an xpt from its dependency list
makes us give all _previous_ dependencies, inherited from the .deps makefiles.
This leads to removed files being listed on xpidl-process.py command line, and
the command subsequently failing.
Instead, use generated lists of idl dependencies. At the same time, lighten the
generated Makefile further by not emitting xpt dependencies on their containing
directory, and instead generating it from the $xpt_files list.
This brings down the Makefile size from 100k to 38k.
Now that the mozbuild backend knows about FINAL_TARGET, we are able to
install generated xpt files into their final location. This saves us
from copying xpt files into their final location on every build.

With these substitutions, it is possible to have comm-central's versions of
these files merely include the mozilla-central versions and avoid having to port
small changes to these files.
win_srcdir is used as the Windows path for the srcdir, and so it needs to use
comm-central's topsrcdir to work properly. In contrast, WIN_TOP_SRC is really
only used to define BUILD_TOOLS, which refers to files in mozilla-central/build,
and so that can and should remain the mozilla-central topsrcdir.
This change allows us to use use MOZILLA_DIR even for changes in config.mk. The
corollary is that comm-central needs to define MOZILLA_DIR before calling into
baseconfig.mk, which it already does.
The change to the test Makefile is needed since it decides to skip including
config.mk, and hence baseconfig.mk, where it would need to grab the MOZILLA_DIR
declaration.
buildlist invocations are slow and can occur in parallel since the
underlying program obtains a lock on the modified file.
Moving the XPT-related buildlist invocation from the serial libs tier to
the parallel misc tier decreased my no-op build time on OS X from 43.5s
to 37.0s.

This used to be necessary to avoid the conflicting names between import
libraries and static libraries, but that's now prevented by the whole
moz.build machinery.
There are, sadly, many combinations of linkage in use throughout the tree.
The main differentiator, though, is between program/libraries related to
Gecko or not. Kind of. Some need mozglue, some don't. Some need dependent
linkage, some standalone.
Anyways, these new templates remove the need to manually define the
right dependencies against xpcomglue, nspr, mozalloc and mozglue
in most cases.
Places that build programs and were resetting MOZ_GLUE_PROGRAM_LDFLAGS
or that build libraries and were resetting MOZ_GLUE_LDFLAGS can now
just not use those Gecko-specific templates.
This hack has actually not been actively used since sqlite, nss and nspr are
all folded together, because no shared library is actually linked in
db/sqlite3/src.
