dev-python: merge most python2 and python3 recipes.

* adjust recipes depending on these, ie python_dateutil=>dateutil_python.
* switch architectures to any for relevant python recipes.
* bump versions for retext, argh, beautifulsoup, cssselect, dateutil,
docutils, fonttools, html2text, httplib2, lxml, mechanize, mock, paramiko,
