e4cad664d8 Implemented lookup of selector with a type for __GNU_LIBOBJC__. We can simply use sel_copyTypedSelectorList() to access the full list of selectors with a certain name.

18ccb48ece Some changes to method type lookup when forwarding. Alway use the compiler-supplied type information if it exists - this is guaranteed to by the correct type encoding for the call frame and lets us deconstruct it correctly. We can then fail gracefully later on when trying to invoke the selector if the types in the callee don't match, rather than by reading nonsense from the stack now. 
When using the GNUstep runtime, use the safe mechanism for checking whether there is more than one typed selector, and only use that as a guess if it is safe to do so.  With the GCC runtime, we are still stuck using the API that it is impossible to use safely (we might be better off just giving up at this point), but now we call this after -methodSignatureForSelector:, so the app developer gets a chance to do the right thing before we do the wrong thing.

Also changed the assert to throw an exception if no type signature can be found.  This behaviour is consistent with Mac OS X.

4488708e84 Fix a load of warnings from implicit function declarations. A lot were caused by ctype.h and string.h stuff being used everywhere in GNUstep but not included anywhere - they're now included in common.h (at least string.h should also be in Foundation.h - on OS X it is implicitly included via some chain of things from Foundation.h). 
All of the sel_* stuff is now replaced with the newer APIs.  As a side-effect, a blob of code that was copied-and-pasted all over GNUstep has now been moved into ObjectiveC2 and just called.

Class posing with libobjc2 will now throw an exception, rather than just aborting.

7a80adeb9b A huge blob of changes to make -base build with libobjc2, without using the old libobjc2 headers. 
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.

47eab60ed8 Added implementations of the hooks provided by the new runtime. This brings 
NSObject up to feature-parity with the OS X 10.5 implementation when using the
new runtime and up to feature-parity with the 10.6 implementation if you are
using the new runtime and compiling with clang.

Also removes the objc_mutex_wibble stuff from NSObject in favour of just using
NSLocks (which, with the new implementation, are now faster than using
objc_mutex_stuff).
