Summary: fix for bug 1055168 (pdb not entering the right frame)

Initial Comment:
Bdb.set_trace()  assumed that the frame which needs to
be debugged is the caller's frame. This assumption
fails if Bdb_set_trace() is called from inside a
debugger (say from inside of a pdb's set_trace). So now
Bdb.set_trace() accepts an optional parameter
frame_to_debug which allows the caller to specify which
frame needs to be debugged, and pdb is modified to use it..

That's normal: pdb can never list code that was input on a
console. A coworker of mine (Jeroen Vloothuis) and I
beautified the code a bit, and I checked it in as rev 1.73
of pdb.py and rev 1.47 of bdb.py. Thanks for the patch!

The original bug report gives an example where the code to
debug was specified from python's shell. I am not quite  how
pdb is supposed to behave in this case.. With the patch, it
does seem to enter in the right frame, but it can't list the
code.

The patch does work when the code comes from a file.
 
.def foo():
     import pdb 
     pdb.set_trace()
     print "tracing 1"
     print "tracing 2"
 foo()
