Small bug fixes:

- Don't check the owner of retain / release methods if they are not implemented.
- Add arc.m as a file to ignore when checking for GC compatibility.

Added a fast path for ARC. Now, if a class implements ARC-compatible retain / release / autorelease methods, we don't call them at all. Instead, we inline them in the ARC accessors. This avoids all of the overhead of the message send (lookup and call) and should make ARC quite a bit faster than manual reference counting.

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.

Added low memory profile to libobjc2. This uses a more NeXT-style dtable design, which gives better memory usage at the cost of (significantly) worse worst-case performance. The memory savings seem to be only about 10% in the apps I've tested (Gorm, edlc), so it's probably not worthwhile, but it might be useful for someone finding stuff is just starting to swap...

No longer installs headers by default. This is because GNUstep Make notices when the objc headers have changed (because GNUstep includes them) and so reinstalling libobjc2 was requiring a complete recompile of anything that you tried to build, even if you only changed one line. A better fix for this would be for install to use cmp or diff to check if the header has been modified before installing it, but I'm too lazy to do that right now.
