* remote.c (struct remote_arch_state): Doc fix.

	* remote.c (struct remote_arch_state): Doc fix.
	(compare_pnums): New function.
	(init_remote_state): Only allocate packet_reg structures for raw
	registers.  Define the g/G packet format separately from creating
	packet_reg.  Don't use DEPRECATED_REGISTER_BYTE.
	(packet_reg_from_regnum, packet_reg_from_pnum): Only iterate over
	raw registers.
	(register_bytes_found): Delete.
	(fetch_register_using_p): Take a struct packet_reg.  Handle disabled
	'p' packet here.  Use packet_ok.
	(fetch_registers_using_g): New function, split out of
	remote_fetch_registers.  Check the 'g' packet more strictly.  Save
	its actual size and contents.  Eliminate BUF.  Only iterate over
	raw registers.
	(remote_fetch_registers): Use the new functions for 'p' and 'g'.
	Mark unavailable registers.
	(store_register_using_P): Likewise to fetch_register_using_p.
	(store_registers_using_G): New function, split out of
	remote_store_registers.  Only iterate over raw registers.  Don't
	use register_bytes_found.
	(remote_store_registers): Likewise to remote_fetch_registers.
