For PHP 5.1.1, I added an additional field $frame['object'] to the
result array of debug_backtrace() that contains a reference to the
respective object when the frame was called from an object.
What I did not think of at the time, unfortunately, is the fact that
unconditionally including $frame['object'] in the result array can get
in the way of using print_r(debug_backtrace()), for instance, for
debugging purposes.
With the patch below, I propose the addition of an optional parameter
$provide_object to debug_backtrace() that toggles the inclusion of
$frame['object'] in the result array.
The value of $provide_object defaults to 1 so as not to break BC.
