Move all of the object matching code to a shared file so it can

be more easily re-used.  This currently uses some cooked up matching
function that I wrote a while ago, but should probably be changed
to use regular expressions in the future.
add doDebugBreak to control breakpoints on a per SimObject basis

SConscript:
    add match
base/stats/events.cc:
base/trace.cc:
    Move the object matching code into a separate file so it can be
    more easily shared
base/trace.hh:
    the object matching code was wrapped up and moved.  adapt.
sim/sim_object.cc:
    add the doDebugBreak flag that can be set on a per-SimObject
    basis.  This will be used in the future to control whether or
    not debug_break() will actually break for a given object.

    provide a function interface that can be called from the debugger.
sim/sim_object.hh:
    add the doDebugBreak flag that can be set on a per-SimObject
    basis.  This will be used in the future to control whether or
    not debug_break() will actually break for a given object.
