[PATCH 7/8] btrace-btrace: signal record-goto stop

[Markus Metzger <markus.t.metzger@intel.com>]

When changing a thread's replay position, call record_signal_goto_stop instead
of printing the source location directly.  This will signal the stop to
front-ends and have them print the source location.

We update the STOP_PC if the change affects the selected thread.

2016-07-06  Markus Metzger  <markus.t.metzger@intel.com>

gdb/
	* record-btrace.c (record_btrace_set_replay): Check ptid before updating
	STOP_PC.  Call record_signal_goto_stop.
