* elf.c: Remove elf_set_section_contents, use generic one. Lint.
* libbfd-in.h, libbfd.c: Add bfd_generic_set_section_contents.
* libbfd.c (bfd_generic_{get,set}_section_contents): Check that
last byte of transfer, not first byte, is within the section.
* host-aout.c: Remove `BSD' archive support. Lint.
* archures.c: Rename `struct bfd_arch_info_struct' to `struct
bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
`bfd_arch_info_type'. All uses changed.
* reloc.c: Rename `bfd_reloc_status_enum_type' to
`bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
it needs a better name.) All uses changed.
* targets.c: Rename `enum target_flavour_enum' to `enum
target_flavour', and remove the `_enum' from all of the enum
values themselves. All uses changed.
* configure.in, config/h-i386mach: i386 mach host.
* config/t-i386-aout: Use host-aout.c.
* trad-core.c: Give it its own xvec's to make it independent
of other file formats.
* ecoff.c, host-aout.c: Remove refs to trad-core.
* config/t-dec3100, t-hp300bsd, t-tahoe, t-vax: Define TRAD_CORE.
* targets.c: #ifdef TRAD_CORE, include it in the vector.
