Mike Hommey 1d537257e2 Bug 1247162 - Generate a header defining MOZ_SOURCE_*. r=mshal
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.
