Declare some Darwin functions as const

[Stan Shebs <shebs at apple dot com>]

A minor improvement extracted from Apple's sources, plus the
removal of a stray decl.  Bootstrapped on powerpc-apple-darwin.

       * darwin.c (func_name_maybe_scoped): Remove unused decl.
       (machopic_function_base_name): Declare result to be const.
       (machopic_non_lazy_ptr_name): Ditto.
       (machopic_stub_name): Ditto.
       * darwin-protos.h: Ditto for the prototypes.
