Use pyrepl as the default input console for pdb

[gaogaotiantian]

Feature or enhancement

Proposal:

Now we have a fancy REPL that supports multi-line editing and real-time coloring, it would be a shame that we don't apply it on pdb. pdb should by default use PyREPL and preserve the old way as fallback.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
