[PATCH 13/23] docs/qapidoc: add visit_errors() method

[John Snow]

Notably, this method does not currently address the formatting issues
present with the "errors" section in QAPIDoc and just vomits the text
verbatim into the rST doc, with somewhat inconsistent results.

To be addressed in a future revision.
