Remove bfd stub function casts.

This patch defines a bunch of new functions to use in the BFD target
structs rather than casting bfd_false or bfd_true and similar stub
functions.  I've also renamed the stub functions to reflect their
parameters and put "error" in the name if they set bfd_error.  The
latter change is important since there were quite a few uses of
bfd_false where setting bfd_error was inappropriate, for example in
elf_backend_allow_non_load_phdr and is_target_special_symbol.
