rHG26127236b229: convert-bazaar: use breezy package instead of old bzr one

Summary

Breezy is the most recent of the two, and works on Python 3 while being
compatible with the (old) Bazaar file format.

This patch contains a variety of unicode <-> bytes changes, API breakage fixing,
restoring failing imports and changing the executable from bzr to brz.

I recommend using the debian packages for brz and python3-breezy (3.1+),
because the pip package seems to be haunted by radioactive dragons.
