util: document bundle compression
An upcoming patch will add support for documenting bundle
specifications in more detail. As part of this, we'd like to
enumerate available bundle compression formats. In order to do
this, we need to provide the help mechanism a dict of names
and objects with docstrings.
This patch adds docstrings to compengine.bundletype and adds
a function for retrieving a dict of them. The code is not yet
used.
