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.

Drop python 2.7 support from a few ports

With hat:	portmgr

Relax hardcoded paths to fix build with Python 3.8.7

Since r558913 Python 3.8 incorporates BPO-42604 [1] which changed the
shared libs naming scheme.  This means "EXT_SUFFIX" is now derived from
SOABI and yields with Python 3.8 to ".cpython-38.so" instead of ".so".

The affected ports strip the libaries in the "post-install" target via
hardcoded path(s) and the build fails at the end because the new extension
is not expected at this place.

Remedy the issue by adding wildcards to these paths.  This should also
prepare the ports for future Python releases, which will use the new shared
libs naming scheme.
