(bsd_write_armap): Save timestamp and file location thereof, when
writing the armap in a BSD file.

in use. If FILE_OFFSET_IS_CHAR_INDEX, assume arithmetic can be done on it,
and ignore SEEK_SET requests that move to the current position.
hosts/sparc.h: Define FILE_OFFSET_IS_CHAR_INDEX.
coffcode.h, elf.c, ieee.c, libaout.h, libbfd.c, oasys.c,
sco-core.c: Lint: Second argument of bfd_seek is always file_ptr.
Third argument is SEEK_SET or SEEK_CUR. Result is always 0 or -1.
* opncls.c (bfd_close_all_done). Added so that generative
programs like gas can close a bfd without causing bfd confusion.
* libbfd.h (changed becuase of protos)
* amdcoff.c: messed with the way that jmp displacements are
calcualated. This may not yet be totally correct.
* archive.c (coff_write_armap): rewrote the way that ranlibs are
written out.
* coffcode.h (fixup_symbol_value): now doesn't core dump if a non
abs symbol has no section (like a register symbol).
(coff_write_symbol) now zeros auxent before filling it up to help
with sensitive applications.
* libbfd.c (bfd_write_bigendian_4byte_int): added.
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.
