* c-parse.in (OBJC_NEED_RAW_IDENTIFIER): Define macro and flag for
contextualizing Objective-C class name lookup by the lexer.
(typespec_reserved_nonattr): Disable ObjC class name lookup after
seeing a TYPESPEC.
(protocoldef): Add support for forward @protocol declarations.
(yylexname): Suppress ObjC class name lookup in certain contexts;
re-enable after lookup is complete.
(_yylex): Re-enable ObjC class name lookup when certain
punctuation marks are seen.
* objc/objc-act.c (check_protocol_recursively): New function used
for finding circular dependencies in protocols.
(objc_declare_protocols): New function for handling forward
@protocol declarations.
(receiver_is_class_object): Detect the case when 'self' is used
inside of a class method.
(build_message_expr): Issue a warning if class method is desired
but instance method is found instead.
(conforms_to_protocol): Streamline.
(objc_comptypes): Detect the fact that 'Bar<Foo> foo' conforms to
protocol Foo, even if 'Bar foo' does not.
(check_protocols): Streamline.
(start_protocol): Add checks for circular and duplicate protocol
definitions.
(encode_aggregate_within): For typedefs of structs, encode the
underlying struct.
* objc/objc-act.h (PROTOCOL_DEFINED): New tree accessor.
(objc_declare_protocols): New prototype.
