[PATCH 0/5 V8] MI notification on trace started/stopped

[Yao Qi <yao at codesourcery dot com>]

Hello,
This is the V8 of the patch series for "MI notification on trace
started and stopped".  In V8, the changes are:

 - Treat notification as a feature in qSupported, to get to know
   a certain notification is supported or not.  It saves much
   code.
 - Call observer_notify_trace_changed only when GDB gets async
   remote notification Trace, so that the notification order is
   consistent in two sides (GDB side and GDBserver side).
 - Consume some notification events on some points in all stop
   mode.  See patch 1/5.

Patch 2/5 is about querying supported notifications.  Patch 3/5
is to add new async remote notification trace.  Patch 4/5 is to
add new MI notification on trace started and stopped.  Patch 5/5
is to add the test cases.

They are tested on x86_64-linux with
{unix, native-gdbserver} x {sync, async}.  Is it OK?

V7 can be found https://sourceware.org/ml/gdb-patches/2013-12/msg00495.html
