[PATCH 0/6 V2] New MI command -trace-frame-collected

[Yao Qi <yao at codesourcery dot com>]

Hi,
In a given traceframe, there are explicitly collected variables,
registers, trace state variables, memories, and computed expressions.
In MI, we don't have a command to dump these contents, and this patch
adds -trace-frame-collected to do so.

Patch 5/6 is the major part of this series, and patch 6/6 is the test
to -trace-frame-collected.  GDB needs to know what trace state
variables are collected in a traceframe, so we extended the
qXfer:traceframe-info object to report the set of collected trace
state variables in the current traceframe.  That is what patch 4/5 does.
Patch 1/6, 2/6  and 3/6 is code refactor.

The whole series are tested on x86_64-linux with native and gdbserver.

This is the V2 of this series.  In V2, there are several changes:

 - Mention some changes in ChangeLog entry and correct comments.
 - Split the changes on encode_actions in a different way, which is more
   readable.
 - Move the change from warning to error to a separate patch.
 - Explain what 'tvar' element does in NEWS.

The V1 can be found <http://sourceware.org/ml/gdb-patches/2013-06/msg00148.html>

*** BLURB HERE ***

Yao Qi (6):
  Remove global variable tracepoint_list and stepping_list.
  Emit error in tdump command when traceframe is not selected.
  Move code to get_traceframe_location.
  Add id of TSV into traceframe_info.
  New MI command -trace-frame-collected
