_bfd_alloc_and_read
This patch provides two new inline functions that are then used in
places that allocate memory, read from file, and then deallocate on a
read failure.
* libbfd-in.h (_bfd_alloc_and_read, _bfd_malloc_and_read): New.
* aoutx.h (aout_get_external_symbols): Replace calls to
bfd_[m]alloc and bfd_bread with call to _bfd_[m]alloc_and_read.
(slurp_reloc_table): Likewise.
* archive.c (do_slurp_bsd_armap): Likewise.
(do_slurp_coff_armap): Likewise.

* ecoff.c (ecoff_slurp_symbolic_header),
(_bfd_ecoff_slurp_symbolic_info, ecoff_slurp_reloc_table),
(_bfd_ecoff_slurp_armap, ecoff_link_add_object_symbols, READ),
(ecoff_indirect_link_order): Likewise.
* elf.c (bfd_elf_get_str_section, setup_group, elf_read_notes),
(_bfd_elf_slurp_version_tables): Likewise.
* elf32-m32c.c (m32c_elf_relax_section): Likewise.
