libobjc2: tweaks to build on Windows

Fix introspection with type-dependent dispatch enabled. Looking up a method with an untyped selector was failing because the UID for the selector was no longer the same for all type variants.
...
As a side-effect of this change, method lookups for introspection are now much faster. They use the slot lookup mechanism to find which class has the method declared and then only need to do the linear search on that class, rather than doing the linear search on the entire hierarchy (slow!). If the method is not present, then they can give up after two memory accesses, rather than after searching a few hundred list entries, but that's a less important case.
I also noticed while tracking down this bug that the implementation of methodSignatureForSelector in GNUstep is very inefficient. I'll tweak that next.

Added a hook that defines the behaviour when you call a method with the wrong signature.

Type dependent dispatch now actually works.

In some irritating circumstances, the load order can cause a +load message to trigger other code, which sends messages with selectors that have not been mapped yet.
...
The runtime was handling the message lookup correctly in this case, but only as a side-effect of the fallback code from when type-dependent dispatch is not possible. This resulted in a confusing warning message, telling you that you were calling a method with an incorrect signature, when the two signatures that it printed were the same.
This case is now handled correctly, so the warning disappears (unless you really are calling a method with the wrong signature and have TDD enabled).

Added low memory profile to libobjc2. This uses a more NeXT-style dtable design, which gives better memory usage at the cost of (significantly) worse worst-case performance. The memory savings seem to be only about 10% in the apps I've tested (Gorm, edlc), so it's probably not worthwhile, but it might be useful for someone finding stuff is just starting to swap...

Fix message forwarding by, for example, actually calling the public forwarding hook, instead of one that isn't exposed to GNUstep...

More tweaks to +load. Now defers +load a little bit more.

Crash in the caller, instead of in the message lookup, when the method does not exist and there is no forwarding hook.

Make sure BOOLs in class tests are always YES or NO.
...
Make self in +load the correct value (the class, not the metaclass).

Fixed unresolved class list loss when the root class gets resolved.
...
Hence not all classes were previously resolved at load time.
Was breaking +forwardInvocation: because unresolved classes such as
GSFFInvocation were not receiving +load right when gnustep-base was loaded.

Added rewritten encoding parser. The functions that function pointers as arguments and parse compound types should be exposed via the public interfaces, or possibly moved to a separate library - they are generally useful.

Remove remaining uses of class_get_class_method and class_get_instance_method, which were causing link errors. David: can you check that I didn't do anthing silly? Thanks.

Removed DLL entry point. The Win32 API docs say that this function is optional, and the implementation was doing exactly the same thing as if it was absent. High quality coding at its finest.

Finished rewriting the loader. It's now cleanly separated into logically-separate components, so there's a chance it might actually be maintainable...

Rewrote ABI compatibility testing. Makes it easier to define new, incompatible ABIs in future without breaking everything.

Tweaked class resolve function to make sure that it keeps scanning the list as long as one or more classes is resolved while scanning it.
