python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal

Any missed ports, feel free to bump.

Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.

all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

mail/rss2email3: Update to 3.11

* This update unbreaks the port at runtime by using the builtin
  "html.unescape()" function (introduced in Python 3.4) instead of the
  "html2text.unescape()" function from textproc/py-text2html which was
  removed since the 2019.8.11 release.

* Submitter becomes maintainer because the previous maintainer seems to be
  missing in action as there was no feedback over five months.

While I'm here:

* Switch manpages to the preferred share/man location.
* Remove no longer required CONFLICTS_INSTALL entry.
* Update the WWW field to point to the new upstream repository.

Convert Python ports to FLAVORS.

  Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the

Allow these ports to build with PACKAGE_BUILDING_FLAVORS set.

Poudriere in particulr did not properly handle DEPENDS_ARGS which
made these ports not properly install dependencies.  That bug
is being addressed along with adding FLAVORS support to it.

- New port: mail/rss2email3

rss2email is a python script that lets you subscribe to a list of
RSS or Atom feeds and get new posts sent to you by email. It is
generally run via cron, but can be run manually as well.

This is a python 3 rewrite of the original rss2email project by
Lindsey Smith at AllThingsRSS. It does not run on python 2.
