More GCKit work. Most stuff is working now, with the big exception being tracing of collectable regions. Test case demonstrates this failure and the success of everything else.

Initial commit of GCKit (moved from Étoilé and the missing 90% mostly implemented). GCKit implements cycle detection on the heap and tracing on the stack and designated heap regions, with support for weak references. It is designed for implementing OS X 10.5-compatible GC semantics.
...
Although GCKit is mostly finished, it is still not well tested. It contains bugs, and possibly dragons. Do not use it. If you disregard this advice, do not file any bug reports. If you disregard this instruction, then I will point and laugh at you.

Fix crash with gcc-compiled protocols.

c1a637a990
Allowed hash tables to dynamically resize. This uses toydispatch to free the old version of the table after copying all of the data into the new one, after waiting enough time to allow all potential readers to finish. There are theoretical cases when this can fail, but hopefully no practical ones. The theoretical cases can be removed by making the garbage thread run at a lower priority than all of the other threads in the system.
...
The protocols table and the class table will now grow as required. Protocols are now added to the protocols table as they are created, so you should get something sensible and introspectable back when you look up a protocol by name.

Ugly hack to fixup NXConstantString references to NSConstantString if linked against Foundation. Now, if you forget to specify -fconstant-string-class=NSConstantString when compiling, stuff will still work and GNUstep won't get confused.

dfa14d5d34
Made Object less magic. For now, because there are some weird people who want to use Objective-C without Foundation, Object is still included. If you compile without defining GNUSTEP (which GNUstep Make does automatically) then you get the old behaviour. If you build with GNUSTEP defined:
...
+load will not be sent until both NSObject and NSConstantString have been seen.
NSObject will be set as the superclass for all metaclasses, not Object.
This is in line with Cocoa and should make it a bit easier for people porting code who have categories on NSObject and are confused that they don't work as expected.
Object and NXConstantString are now deprecated. They're staying here because I use them for producing reduced test cases for the runtime and compiler, but they shouldn't be used. I will probably remove them from the default build soon.

Added toydispatch to libobjc. This is an implementation of a tiny subset of libdispatch, requiring no kernel support beyond a standard pthread implementation. It is intended to be used for running asynchronous book-keeping tasks for libobjc, but might also be useful for other things so it's compiled as a separate library.

Fixed a bug with category loading. Previously, a method in a category that overrode a method in the superclass would only be picked up by subclasses that were not yet initialized.
...
Quentin: This was the category loading problem that you saw. It was dependent upon load order, so was difficult to reproduce, however a Smalltalk category on NSString overriding a method from NSObject demonstrated it (because GSString was always initialized by the time Smalltalk code is loaded because LKCompiler use it, but not by the time ObjC code is loaded).

Initial work on protocol uniquing. Protocols are now added to a table and can be looked up at run time.

bdf97cf64e
Added hopscotch table implementation and rewrote the class table to use it. This is done so that the class table and protocol tables can share the same code (currently there is no protocol table).
...
Note that concurrent resizing has not yet been implemented. That means that there is a hard limit on the number of classes that can be loaded. This is currently set to quite a small number for testing, to stress the hash table. If you're experiencing problems as a result, then please let me know and I will increase it.

Fixed class_get_super_class() so that it actually works and simplified class_getSuperclass() to call it directly. This fixes numerous other corner cases, for example you can now throw a constant string as an exception and have it work correctly even if no constant string objects have been sent messages.
...
Hopefully this will fix a few other Heisenbugs and reduce the strength of the Mottola Effect.
