Don't send retain / release messages in GC mode when copying object pointers into blocks.

Lock the GC mode once something has queried it. All of the GNUstep code that
...
does run-time detection of whether to use GC calls objc_collecting_enabled()
(sometimes indirectly, via NSGarbageCollector) to see if we're in GC mode.
After any of these calls, it is not safe to switch modes.

Tweak GC check, make sure GC_init() is called even when ObjC code isn't using GC (stuff internal to the runtime may be)

Initial support for running finalizers in a separate thread.

Sometimes people assign things like classes to __weak pointers. This confuses the GC, because it expects to be able to finalize / delete things that are the target of disappearing links.

Use typed allocations for the hash table entries. This makes sure that the GC won't treat the jump table bitfield as a pointer.
...
Store the refcount structures inside the hash table, rather than in a chained structure. This uses less space and should be easier for the GC to scan (less cache used).

If we're linking against Boehm GC, then we may as well allow it to collect the runtime's hash tables, rather than doing that manually.

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.

Added a really ugly hack so that the ABI versions of the three .m files are not checked. This will (hopefully!) prevent the GC being enabled when libobjc is loaded after being compiled with -fobjc-gc.

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.
