rustbuild: Rewrite user-facing interface
This commit is a rewrite of the user-facing interface to the rustbuild build system. The intention here is to make it much easier to compile/test the project without having to remember weird rule names and such. An overall view of the new interface is: # build everything ./x.py build # document everyting ./x.py doc # test everything ./x.py test # test libstd ./x.py test src/libstd # build libcore stage0 ./x.py build src/libcore --stage 0 # run stage1 run-pass tests ./x.py test src/test/run-pass --stage 1 The `src/bootstrap/bootstrap.py` script is now aliased as a top-level `x.py` script. This `x` was chosen to be both short and easily tab-completable (no collisions in that namespace!). The build system now accepts a "subcommand" of what to do next, the main ones being build/doc/test. Each subcommand then receives an optional list of arguments. These arguments are paths in the source repo of what to work with. That is, if you want to test a directory, you just pass that directory as an argument. The purpose of this rewrite is to do away with all of the arcane renames like "rpass" is the "run-pass" suite, "cfail" is the "compile-fail" suite, etc. By simply working with directories and files it's much more intuitive of how to run a test (just pass it as an argument). The rustbuild step/dependency management was also rewritten along the way to make this easy to work with and define, but that's largely just a refactoring of what was there before. The *intention* is that this support is extended for arbitrary files (e.g. `src/test/run-pass/my-test-case.rs`), but that isn't quite implemented just yet. Instead directories work for now but we can follow up with stricter path filtering logic to plumb through all the arguments.
