abfe4e2a04 Use native threading and locking APIs on Windows 
Removes dependency on pthread library and uses fast Slim Reader/Writer (SRW) locks for NSLock/NSRecursiveLock/NSCondition/NSConditionLock as well as all internal locks. Adds GS_MUTEX_*() macros in GSPThread.h, that are being used for all internal locking instead of pthread APIs.

Also adds support for thread priorities on Windows, fixes method signature of +[NSThread setThreadPriority:] to match Apple platforms, and adds error handling in same method.

7bf1179f60 Reapply 3b1e94ec5d correctly 
This time without accidentally-included files...

If compiling without backtrace or BFD support, we initialise the
location to store return addresses incorrectly, leaving a dangling
pointer which we then right over.

Most consumers never read this, so it seemed to work most of the time by
just overwriting a random bit of memory.

This probably has security implications, because throwing an exception
can clobber random bits of memory, though not with attacker-controlled
data.

7764740bdc Make -drain and -release in NSAutoreleasePool do the same thing (rather than one calling the other) in non-GC mode. 
Replace all -release messages sent to autorelease pools with -drain.  In non-GC mode, these are equivalent.  In GC mode, these trigger a collection.
