[PATCH] One more for MI trace status

[Stan Shebs <stan@codesourcery.com>]

[-- Attachment #1: Type: text/plain, Size: 570 bytes --]

There is one more field that's been overlooked for trace_status_mi - 
total frames created.  (More trace status additions are coming, perhaps 
we should revisit the idea of sharing CLI and MI versions...)

I note that MI commands for tracing need testsuite.  But there's a 
conundrum; should tests go in gdb.mi or gdb.trace? :-)

    * tracepoint.c (trace_status_mi): Report frames created.

    * gdb.texinfo (gdb/mi Tracepoint Commands) <-trace-status>:
    Describe the `frames-created' field, tweak grammar.
