Jeff Law 250578363e * libbfd.c (bfd_read): Set bfd_error as appropriate for a short 
read. (bfd_error_system_call or bfd_error_file_truncated).

        * som.c: Do not blindly set bfd_error_system_call after a
        failing bfd_read, bfd_write, or bfd_seek.  In a few places
        (like som_object_p) override the error status set by bfd_read.

        * aix386-core.c, aout-encap,c archive.c, bout.c: Likewise.
        * coff-rs6000.c, coffgen.c ecoff.c, elf.c: Likewise.
        * elf32-hppa.c, elfcode.h, hp300hpux.c, i386lynx.c: Likewise.
        * nlm32-alpha.c, nlm32-i386.c, nlm32-sparc.c: Likewise.

        * som.c: Check return values from several bfd_{seek,read,write}
        calls that we just assumed were not failing.

David MacKenzie 9783e04a64 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>".

optional_prefix_size, nlm_backend_object_p, nlm_write_prefix,
	nlm_set_public_section, nlm_get_public_offset.  Removed unused
	nlm_write_reloc field.  Changed nlm_write_import to remove
	unnecessary symbol argument.  Renamed nlm_write_externals to
	nlm_write_external, and changed cound argument from bfd_vma to
	bfd_size_type.

	Declared.  Changed second argument from bfd_vma to bfd_size_type.

	(nlm_object_p): Don't destroy tdata pointer.  Call
	backend_object_p function if it exists.
	(nlm_slurp_symbol_table): Removed unused variable rcount.  Call
	set_public_section_func if it exists instead of checking
	NLM_HIBIT.
	(nlm_compute_section_file_positions): Account for
	optional_prefix_size.
	(nlm_write_object_contents): Account for optional_prefix_size.
	Removed useless variable write_reloc_func.  Changed declaration
	and call of write_import_func.  Call write_prefix_func if it
	exists.  Removed unused variables len and temp.  Call
	get_public_offset_func if it exists rather than setting NLM_HIBIT.
