A new MI notification 'command param changed' was added to GDB CVS
mainline some weeks ago, and MI frontend should get the notification 
when stop note is changed by 'set trace-stop-notes' command.

(gdb)
set trace-stop-notes bar
&"set trace-stop-notes bar\n"
=cmd-param-changed,param="trace-stop-notes",value="bar"
^done

This notification (along with other notifications I added recently) is 
to address the difficulties you mentioned (MI frontend has to query GDB 
to get some states of GDB).
