Some cleanup for libpdb.

This patch implements a few of the optional suggestions from the
initial patch comitting libpdb.  In particular, it implements a
virtual function out of line for each of the concrete classes.

A few other minor cleanups exist as well, such as using override
instead of virtual, etc.
