* objc/objc-api.h: Define Method, Method_t, Category and
Category_t. Prevent including this file at the same time as
objc/runtime.h. Updated comments.
* objc/deprecated/struct_objc_method.h: Do not define Method,
Method_t.
* objc/deprecated/struct_objc_category.h: Do not define Category,
Category_t.
* objc-private/module-abi-8.h: New file containing a copy of all
the structure definitions. Not used yet.
* objc/encoding.h (objc_aligned_size): Removed duplicate
declaration. Updated comments.
* objc/runtime.h: Added Ivar, objc_property_t, Property, Method,
Category, struct objc_method_description, _C_ID and similar,
_C_CONST and similar and _F_CONST and similar. Added
objc_sizeof_type, objc_alignof_type, objc_aligned_size,
objc_promoted_size, objc_skip_type_qualifier, objc_skip_typespec,
objc_skip_offset, objc_skip_argspec, objc_get_type_qualifiers,
struct objc_struct_layout, objc_layout_structure,
objc_layout_structure_next_member, objc_layout_finish_structure,
objc_layout_structure_get_info. Prevent including this file at
the same time as objc/objc-api.h.
