* opncls.c (_bfd_new_bfd_contained_in): Copy "iovec".
(struct opncls, opncls_btell, opncls_bseek, opncls_bread)
(opncls_bwrite, opncls_bclose, opncls_bflush)
(opncls_bstat, opncls_iovec, bfd_openr_iovec): Implement a
bfd iovec that uses function callbacks.
(bfd_close): Use the iovec's bclose.
* cache.c (cache_btell, cache_bseek, cache_bread, cache_bwrite)
(cache_bclose, cache_bflush, cache_bstat)
(cache_iovec): New functions and global variable, implement a
cache "iovec", where applicable set bfd_error.
(bfd_cache_init, bfd_cache_close): Set/test the bfd's iovec.
* bfdio.c (struct bfd_iovec): Define.
(real_read): Delete function.
(bfd_bread, bfd_bread, bfd_bwrite, bfd_tell, bfd_flush, bfd_stat)
(bfd_seek, bfd_get_mtime, bfd_get_size): Use the bfd's "iovec",
assume that bread and bwrite set bfd_error.
* bfd.c (struct bfd): Add "iovec", update comments.
* bfd-in2.h, libbfd.h: Re-generate.
