Make all callers of malloc or realloc (including via obstacks) 

check the result for NULL.  Most set bfd_error to no_memory and
	return in that case; a few are harder to fix, and are marked
	with "FIXME <return type>".

Now, the thing is that GDB users will be surprised
if segments just silently don't appear (well, maybe they would
think to check "info files", I don't know), but we have no way of
returning warnings (as opposed to errors).
For the data segment, we have no choice but to keep going if it's
not there, since the default behavior is not to dump it (regardless
of the ulimit, it's based on SA_FULLDUMP). But for the stack segment,
if it's not there, we refuse to have anything to do with this core
