David Chisnall c3c81796ca Rework slot handling so that the fields that are used for dispatch are 
at the start of the structure, making it easier to change the layout in
the future.

Also clean up the growth of various fields and consolidate some of the
metadata into a pointer to the `struct objc_method`.

theraven c73b7a2f0b Mark all libobjc2 headers as system headers when not compiling the runtime 
itself.  This makes clang hide warnings.

theraven 535ba87a8e Store the selector, not the type encoding, in slots. 15 years ago
theraven e9b129d878 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... 16 years ago
theraven 2d84b96a72 Tidied up some bits by creating private headers for private data structures. 
Imported selector table code frm the Étoilé runtime.  We can now make dispatch type dependent with a -D switch.  Not enabled yet, but it will be enabled in a warning mode soon - I consider preferable to the existing GNU and Apple solution of corrupting the stack.
