Bug 1402012 - Update buildconfig.py to use PartialConfigEnvironment; r=glandium By using the PartialConfigEnvironment, the clients of buildconfig will depend on config.statusd/ files instead of config.status directly. Clients can access substs and defines using buildconfig.substs['FOO'] or buildconfig.defines['BAR'], and then collect file-level dependencies for make using buildconfig.get_dependencies(). All GENERATED_FILES rules already make use of this because file_generate.py automatically includes these dependencies (along with all python modules loaded). As a result of this commit, re-running configure will no longer cause the world to be rebuilt. Although config.status is updated, no build steps use config.status directly and instead depend on values in config.statusd/, which are written with FileAvoidWrite. Since those files are not official targets according to the make backend, make won't try to continually rebuild the backend when those files are out of date. And since they are FileAvoidWrite, make will only re-run dependent steps if the actual configure value has changed. As a result of using JSON to load data from the config.statusd directory, substs can be unicode (instead of a bare string type). generate_certdata.py converts the subst manually to a string so the value can be exported to the environment without issue on Windows. Additionally, patching the buildconfig.substs dict no longer works, so the unit-symbolstore.py test was modified to patch the underlying buildconfig.substs._dict instead. The other files that needed to be modified make use of all the defines for the preprocessor. Those that are used during 'mach build' now use buildconfig.defines['ALLDEFINES'], which maps to a special FileAvoidWrite file generated for the PartialConfigEnvironment.
