[Dodji Seketeli <dodji src gnome org>]

commit 44fbb0c64370e8a6a02bad78b2de195c2c6a5352
Author: Dodji Seketeli <dodji redhat com>
Date:   Sun Apr 19 20:59:12 2009 +0200

    Allow IDebugger::list_frame to ask for a range of frames
    
    	* src/dbgengine/nmv-i-debugger.h (IDebugger::list_frame): Add new
    	two new parameters to allow asking for a range of frames,
    	and not necessarily for all of them.
    	* src/dbgengine/nmv-gdb-engine.h (GDBEngine::list_frames): Adjust
    	signature.
    	* src/dbgengine/nmv-gdb-engine.cc (GDBEngine::list_frames): Adjust
    	signature and pass on the right arguments to -stack-list-frames to
    	for a frame window.
