pr14813 revisted

[Alan Modra <amodra at gmail dot com>]

When HJ fixed PR14183 he chose to make bclose return a boolean, with
true denoting success.  That's fine except that the doco wasn't
updated.  Also, all the other iovec functions return an int with zero
meaning success.  Rather than update the documentation, this patch
changes the code back to returning zero for success.

	PR binutils/14813
	* bfdio.c (struct bfd_iovec <bclose>): Revert 2012-11-06.
	(memory_bclose): Likewise.  Return 0 on success.
	* cache.c (cache_bclose): Likewise.
	* opncls.c (opncls_bclose, bfd_close): Likewise.
	* vms-lib.c (vms_lib_bclose): Likewise.
	* libbfd.h: Regenerate.
