* remote.c (bin2hex, hex2bin): New functions.  Factor out these
	two conversions which are coded for repeatedly in this module.
	(remote_threads_extra_info, remote_wait, remote_async_wait,
	store_register_using_P, remote_store_registers, remote_write_bytes,
	remote_read_bytes, remote_rcmd): Use bin2hex and hex2bin instead
	of coding the conversions inline.
	(fromhex): Not exported, change from extern to static.
