Check return status of memory alloc functions
This fixes a number of places that call a memory allocation function
without checking for a NULL return before using.
* mach-o.c (bfd_mach_o_flatten_sections): Return a bfd_boolean,
FALSE if memory alloc fails. Adjust calls.
* som.c (som_prep_for_fixups): Likewise.
* vms-alpha.c (alpha_vms_add_fixup_lp, alpha_vms_add_fixup_ca),
(alpha_vms_add_fixup_qr, alpha_vms_add_fixup_lr),
(alpha_vms_add_lw_reloc, alpha_vms_add_qw_reloc): Likewise.
* som.c (som_build_and_write_symbol_table): Return via error_return
on seek failure.
* vms-alpha.c (VEC_APPEND): Adjust for vector_grow1 changes.
(VEC_APPEND_EL): Delete.
(vector_grow1): Return pointer to element. Catch overflow.
Return NULL on memory allocation failure.
(alpha_vms_add_fixup_lp): Replace VEC_APPEND_EL with VEC_APPEND.
(alpha_vms_add_fixup_ca): Likewise.
(alpha_vms_link_add_object_symbols): Check VEC_APPEND result
before using.
* elf.c (bfd_section_from_shdr): Check bfd_zalloc2 result.
