Added some new interfaces, and a new entry in the target vector. Under the new
interfaces, mmap will be used if available, otherwise malloc/seek/read, as
before. Old interfaces all still intact.
Most configurations (including all used by "--enable-targets=all") simply
changed to call the default routine for that entry in the target vector. I
might've missed some targets only included in special configurations.
Support for a.out symbol and string table reading now goes through new
interfaces, and will use mmap when available.
Linker hooks (e.g., avoiding reallocation under malloc) not ready yet.

* coffcode.h: Moved many generic functions into coffgen.c. Moved
swapping functions into coffswap.h for ECOFF use. Moved
relocation functions, only used by h8300 and z8k, into reloc16.c.
Added hooks for coffgen.c functions to backend data structure, and
added hook functions. Still more could be done.
* coffswap.h: New file to hold COFF swapping routines.
* coffgen.c: New file to hold generic COFF functions.
* reloc16.c: New file to hold h8300 and z8k specific relocation
functions.
* libcoff-in.h: Added declarations for functions in coffgen.c.
* libcoff.h: Rebuilt to incorporate changes.
* coff-h8300.c: Function name changes.
* coff-z8k.c: Function name changes. Use coff_reloc16_extra_cases
hook rather than defining EXTRA_CASES.
* Makefile.in: Build new files coffgen and reloc16. Added
dependencies of coff-*.o on coffswap.h and seclet.h.
