use this new class, rather than explicit reference-counting or
cleanups.  This patch removes make_cleanup_bfd_unref.

of gdb_bfd_ref_ptr would be cleaner.  These will be fixed in the next

I think this patch fixes some latent bugs.  For example, it seems to
me that previously objfpy_add_separate_debug_file leaked a BFD.

I'm not 100% certain that the macho_symfile_read_all_oso change is
correct.  The existing code here is hard for me to follow.  One goal
of this sort of automated reference counting, though, is to make it
more difficult to make logic errors; so hopefully the code is clear
now.
