[Tom Tromey <tromey@redhat.com>]

This moves the global remote_traceframe_number into remote_state.

	* remote.c (struct remote_state) <remote_traceframe_number>:
	New field.
	(remote_traceframe_number): Remove.
	(new_remote_state, remote_open_1, set_remote_traceframe)
	(remote_trace_find): Update.
