Ok, I think it's reached the point where I'd like to ask for formal
approval.

Included in this patch are some additional internal consistency checking
points, and documentation updates.  I also moved the inclusion of osabi.h
into defs.h, since this stuff is somewhat tightly coupled to the whole
gdbarch framework.

	* Makefile.in (SFILES): Add osabi.c.
	(defs_h): Add osabi.h.
	(COMMON_OBS): Add osabi.o.
	(osabi.o): New dependency list.
	* defs.h: Include osabi.h.
	* osabi.c: New file.
	* osabi.h: New file.
	* doc/gdbint.texinfo: Document new generic OS ABI framework.

	* alpha-tdep.c (alpha_abi_names, process_note_abi_tag_sections,
	get_elfosabi, alpha_abi_handler_list, alpha_gdbarch_register_os_abi):
	Remove.
	(alpha_gdbarch_init, alpha_dump_tdep): Use generic OS ABI framework.
	* alpha-tdep.h (alpha_abi): Remove.
	(gdbarch_tdep): Use generic OS ABI framework.
	* alpha-linux-tdep.c (_initialize_alpha_linux_tdep): Use
	gdbarch_register_osabi.
	* alpha-osf1-tdep.c (_initialize_alpha_osf1_tdep): Likewise.
	* alphafbsd-tdep.c (_initialize_alphafbsd_tdep): Likewise.
	* alphanbsd-tdep.c (_initialize_alphanbsd_tdep): Likewise.

	* config/sh/tm-sh.h (sh_osabi): Remove.
	(sh_abi, gdbarch_tdep, register enum): Move to...
	* sh-tdep.h: ...here.
	(gdbarch_tdep): Use generic OS ABI framework.
	* sh-tdep.c: Include sh-tdep.h.
	(sh_osabi_names, process_note_abi_tag_sections,
	sh_osabi_handler_list, sh_gdbarch_register_os_abi): Remove.
	(sh_gdbarch_init, sh_dump_tdep): Use generic OS ABI framework.
	* sh3-rom.c: Include sh-tdep.h.
	* shnbsd-tdep.c: Include sh-tdep.h.
	(_initialize_shnbsd_tdep): Use gdbarch_register_osabi.
