This renames the Python 2 twisted package to python-twisted, and updates
dependents (i.e. obfsproxy) to reference the updated name.

This also fixes conflicts between the Python 2 and 3 packages. Twisted
installs some scripts to /usr/bin, and previously scripts for both
packages used the same names. This adds a "3" suffix to scripts
installed by python3-twisted.

This also adds python[3]-setuptools as a dependency, as the scripts
installed to /usr/bin depend on pkg_resources (part of setuptools).

This guarantees for the package feeds that
the mk files will always be available for all packages.

Will need to see about external-feed Python packages
a bit later.

From the Tor project page:

obfsproxy is a tool that attempts to circumvent censorship, by
transforming the Tor traffic between the client and the bridge. This
way, censors, who usually monitor traffic between the client and the
bridge, will see innocent-looking transformed traffic instead of the
actual Tor traffic.

This depends on:

- pyptlib (#2053)
- twisted (#2052)

Also, txsocksx (#2058) is necessary to use an outgoing SOCKS proxy,
and having either gmpy2 (#2067) or gmpy (#2051) installed will help
speed up calculations.
