Some cleanup for uril_uri:

- eliminate a few warnings
- get rid of the static local in parse_uri_components_regex by
  creating util_uri_init() routine called from main()
- don't use static re.match 'cause it's not thread safe
- factor some common code from the win32 and unix case into common_init()
- update dependencies

still hacking.
