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.

swapping functions into coffswap.h for ECOFF use. Moved

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.

someday.
archures.c (bfd_default_scan): Recognize a few more numbers: 80486, 80960,
and 960.

swap table to backend data.
hosts/i386linux.h: Include unistd.h.
aoutx.h, libaout.h, stab-syms.c: stab names are now in constant storage.
trad-core.c: Fixed some `PARAMS' uses that were missing parentheses.
aoutx.h, archive.c, archures.c, coffcode.h, ctor.c, reloc.c, syms.c: Doc fixes.
"done_lineno" so that a symbol which appears twice in the symbol
table only gets it's linenumbers relocated once. Modifed
(coff_write_native_symbol) and (coff_make_empty_symbol) to make
* configure.in: now h8 is a coff target
* cpu-h8300.c: fix various disassembly problems
* libcoff.h: took out some code which has been #0ed for a long
time.
* targets.c: added h8 coff
* coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c

segments): used BFD (caps) more consistently as a name in
discourse, fixed a few other minor typos and uses of fonts
Install header comments and attribute most modules to their
authors. BFD's name is now officially "Binary File Descriptor",
so remove any conflicting perjoratives.
alignments of structures on disk and structures in memory. #ifed out
all the code in coffswap.c, since it should be done using the target
swap routines now.
Remove obstack.h to ../include and obstack.c to ../libiberty.
Move COFF symbol swapping code to coffswap.c where GDB can call it but it
won't be duplicated if we have N different COFF targets.
Add support for traditional Unix core files (with a upage). This support
is from an Ultrix port, but is probably slightly broken now.
Improve bfd_release's of obstack'd items on error returns.
gcc -Wall fixes.
Handle section alignment slightly better in coff, and comment where it
needs more work (on page-aligning virtual vs file addresses for DPAGED).
Use set_tdata everywhere that tdata is set, to avoid "cast to the left
of assignment" problems with some compilers.
Move bfd_alloc, bfd_zalloc, bfd_realloc, and bfd_release into libbfd.h
(from bfd.h) since they are internal routines.
Remove the redundant suffix "_struct" from struct tags.
Set symbol count early in file reading, before slurping in the syms,
for GDB's use.
