	* gdb.cxx (read_bus_word): Now returns bus::status. Return status
	from bus->read.
	(write_bus_word): Ditto for status from bus->write.
	(process_get_mem): Back out previous patch. Retry access
	one byte at a time if bus::misaligned is returned from downstream.
	(process_set_mem): Ditto.

	* cache.cxx (write_any): Allow misaligned access. Return
	bus::misaligned for accesses which cross line boundary.
	(read_any): Ditto.

	* sidcomp.cache/misaligned.exp: 16 bit access should now be a hit.
