Fix building without GC support. Still need to make sure that some of the GC functions always work, since they are expected to be no-ops in non-GC mode.

Blocks do not yet support __weak bound variables. This needs fixing before the release.

First pass at implementing Apple-compatible GC using Boehm. Still needs some tidying, but the following work:
...
- __strong pointers, preventing objects from being freed
_ __weak pointers are automatically freed when the last remaining __strong pointer goes away
- objc_gc_{retain,release}_np() functions, which can be used to implement CFRetain() and CFRelease() (adds an reference count - the object will not be collected until after its last retain is gone.
