More patches from Jeff Law, plus a little cleanup of my own.

These changes separate PA-SOM support from PA-ELF support.
A sun4-x-hppaosf assembler can now be built.

* elf32-hppa.c (elf_hppa_howto_table): Now static.
(symext_rootP, symext_lastP, global_value, GOT_value, global_symbol,
global_sym_defined, symextn_contents, symextn_contents_real_size,
elf_hppa_stub_rootP, elf32_hppa_symextn_map, elf32_hppa_symextn_map_size): Rely
on default initialization.
(hppa_elf_gen_reloc_type): Macro "UNDEFINED" doesn't need a trailing semicolon.
(hppa_look_for_stubs_in_section): Introduce temporaries to make code more
readable in 80 columns.

* libhppa.h (all functions): Now inline under GNU C.

* elf32-hppa.c (AR_WARN): Give argument which caused the invalid argument
relocation.
(AR_UNIMP): Delete unused macro.
(hppa_elf_set_section_contents): Always return a value.
(elf32_hppa_backend_table_processing): Likewise.
(elf32_hppa_backend_section_processing: Likewise.

* som.c: New file containing SOM specific code extracted from hppa.c

* som.h: New file containing SOM specific code extracted from libhppa.h

* hppa.c: Deleted.

* libhppa.h: Delete SOM specific code.  Add generic PA code which can be shared
by both SOM and ELF backends.

* Makefile.in: Replace hppa.c with som.c.  elf32-hppa.o depends on libhppa.h
now.

* configure.in (hppa_vec): Needs som.o module instead of hppa.o.

* elf32-hppa.c: Include libhppa.h.  Do not define BYTES_IN_WORD.

* elf32-hppa.h (hppa_reloc_field_selector_type): Delete now lives in libhppa.h.
(hppa_reloc_field_selector_type_alt): Likewise.

* elf32-hppa.c (hppa_elf_relocate_unwind_table): Delete unused variables.
(elf_hppa_reloc_type_lookup): Likewise.
(elf_hppa_tc_make_sections): Likewise.
(hppa_elf_arg_reloc_needed_p): Likewise.
(hppa_elf_build_long_branch_stub): Likewise.
(elf_reloc_map): Delete, no longer used.
(elf_hppa_reloc_map): Likewise.
(elf32_hppa_symextn_map_max_size): Likewise.
(elf32_hppa_get_sym_extn): Abort if type is bogus.

* elf32-hppa.c (elf32_hppa_backend_fake_sections): Add processing
of the .hppa_unwind section.
