* arch-utils.c (gdbarch_info_init): Set osabi to

	GDB_OSABI_UNINITIALIZED.
	* gdbarch.sh: Add osabi to struct gdbarch and to struct
	gdbarch_info.  Include "osabi.h" in gdbarch.c.  Check osabi
	in gdbarch_list_lookup_by_info and in gdbarch_update_p.
	* gdbarch.c: Regenerated.
	* gdbarch.h: Regenerated.
	* osabi.c (gdbarch_lookup_osabi): Return GDB_OSABI_UNINITIALIZED if
	there's no BFD.
	(gdbarch_init_osabi): Remove osabi argument; use info.osabi.
	* osabi.h (enum gdb_osabi): Move to defs.h.
	(gdbarch_init_osabi): Update prototype.
	* defs.h (enum gdb_osabi): Moved here.
	* Makefile.in: Update dependencies.

Plus updates to alpha, arm, hppa, i386, mips, ns32k, ppc, sh, sparc, and vax
ports to match.
