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.

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.

One more small cleanup, forgotten yesterday.

Corrected shared library names that got the .abi3 suffix for python-36 and up
after devel/py-cffi upgrade to 1.11.2

This is the followup for the r457997 commit that updated devel/py-cffi to
1.11.2.
As it turned out, the shared object names built by py-cffi has changed in python
36.
Dependent ports can choose between installing such shared object as part of
their plist, or
generating them in the runtime and placing them into ~/.cache/{port-name}/ The
former ones,
that include the shared objects in their plist, got affected.

4 of the ports were failing explicitly in their py36 flavor during the strip
phase.
The other 6 were either missing strip entirely, or performed the strip operation
without
using explicit shared object names. These 6 ports didn't trigger any build
errors, and were
failing silently during the runtime, making the problem very hard to detect.

Precisely, .abi3 suffix is now added for the py36 flavor of relevant ports.

Here are the 10 ports that got affected and are now corrected:
databases/py-psycopg2cffi devel/py-pygit2 devel/py-xattr devel/py-pyopencl
devel/py-atomiclong
multimedia/py-librtmp net/py-nnpy security/py-bcrypt security/py-cryptography
security/py-pynacl

All of them got the * in the stripped shared object name, and a PORTREVISION
bump.

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
