Merge pull request #2882 from takluyver/utils-cleanup...
Merge pull request #2882 from takluyver/utils-cleanup Utils cleanup. This removes various unused code that was sitting in IPython.utils. I checked that we don't use these functions and modules at present, but we may want to leave some of them for future use or for extension authors. For the first pass, I've been deliberately quite aggressive about removing things.

""" Debug a script (like %run -d) in IPython process, Using WinPdb
Usage:
%wdb test.py
run test.py, with a winpdb breakpoint at start of the file
%wdb pass
Change the password (e.g. if you have forgotten the old one)
Notes
-----
**WARNING**: As of March 2009 (IPython 0.10), WinPdb has a known bug, which
causes PyTables to become impossible to import if winpdb is loaded. Therefore,
if you need PyTables, do *not* use this extension.
For more details: https://bugs.launchpad.net/ipython/+bug/249036
