    rustbuild: Rewrite user-facing interface · a270b801
    Alex Crichton authored
    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.
