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.
Richard: I'm unsure about three of these, which were fixes in memset() calls in:
- NSConcreteMapTable.m
- NSConcreteHashTable.m
- Additions/NSData+GNUstepBase.m
Please can you check them? I think they are intended to zero the entire object
(rather than the first word), but the lack of comments makes me unsure.
Most changes were just tweaks to variable types. I've also removed some dead code from NSInvocation. This was small group of things that were marked for internal use only, but not actually referenced in the code anywhere.
Other improvements:
- NSArray / NSDictionary fixed up to use the 10.7 (ARC-friendly) prototypes.
- getObjects:andKeys: implemented for NSDictionary (10.5 method)
- NSPointerArray and NSHashTable now properly support weak objects.
- Tests for weak objects in collections.

Replace all -release messages sent to autorelease pools with -drain. In non-GC mode, these are equivalent. In GC mode, these trigger a collection.

Most of these changes involve simply removing direct manipulation of any runtime structures and replacing them with runtime function calls. For example class->name becomes class_getName(class) and so on.
libobjc2, like the Apple runtime, the NeXT runtime, and every version of the Objective-C spec, calls the class pointer in id isa. A few files now have #define class_pointer isa at the top. This line replaces class_pointer in the old GNU libobjc headers with isa so either class_pointer or isa can be used for accessing the class of an object. Note: object_getClass() should be used in most cases because, in some future version of the runtime, this will skip things like lock classes and other hidden classes (e.g. KVO classes).
All of the old forwarding stuff has been removed. Most of this stuff followed convoluted code paths that ended with an exception. A few simply broke in exciting ways. Hopefully no one has used them for the last ten years or so, but we can bring them back with some #ifndef stuff if they're really needed by anyone.
There is currently a bug in configure, which prevents dladdr() from being detected, so you need to manually tweak config.h to build - I have not fixed the fall-back code in objc-load.m to work with libobjc2, I just added a new version that uses the loader's functionality directly.
Although -base now builds, it builds with a lot of warnings. <string.h> is missing from a lot of files, so memcpy() and strlen() generate implicit function declaration warnings.
Additionally, libobjc2 does still provide the sel_{get,register}_*() functions, but they're wrappers around the newer API ones. These are deprecated and are not exposed in the headers. Although they work, we should be replacing them with the libobjc2 versions as soon as possible.
This incorporates a patch by Eric.
