theraven 9dcc66f7f6 Make sure that associated objects and blocks use GC-scanned memory in GC mode. 
Blocks do not yet support __weak bound variables.  This needs fixing before the release.

theraven 929f8f95b4 Improved a few GC functions. 
Added objc-auto.h header, providing (documented) public interfaces to this
functionality.

theraven ad16172625 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.
