[PATCH 08/16] push last_program_signals_packet into struct remote_state

[Tom Tromey <tromey at redhat dot com>]

This moves the global last_program_signals_packet into remote_state.

	* remote.c (struct remote_state) <last_program_signals_packet>:
	New field.
	(last_program_signals_packet): Remove.
	(remote_program_signals, remote_open_1): Update.
