* opncls.c (bfd_alloc_by_size_t): Set bfd_error_no_memory if

Browse Source 
obstack_alloc fails.
	(bfd_alloc_finish): Set bfd_error_no_memory if obstack_finish
	fails.
	* libbfd.c (bfd_zmalloc): Set bfd_error_no_memory if malloc fails.
	* Many files: don't set bfd_error_no_memory if one of the above
	routines fails.

the bfd client will have to interpret the structures itself. Even with
/proc support, it might want these full structures for it's own reasons.
In the second level of support, where HAVE_PROCFS is defined, bfd will
pick apart the structures to gather some additional information that
clients may want, such as the general register set, the name of the
exec'ed file and its arguments, the signal (if any) that caused the
core dump, etc.
