Move bfd_alloc, bfd_zalloc and bfd_release to libbfd.c
These functions don't belong in opncls.c.
* libbfd-in.h (bfd_release): Delete prototype.
* opncls.c (bfd_alloc, bfd_zalloc, bfd_release): Move to..
* libbfd.c: ..here. Include objalloc.c and provide bfd_release
with a FUNCTION comment.
* bfd-in2.h: Regenerate.
* libbfd.h: Regenerate.
