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.

security/libsodium: update to 1.0.19, bump dependent ports

PR:	278259
Reported by:	Andrey Korobkov <alster-vinterdalen.se>

*: Change {RUN,TEST}_DEPENDS from security/py-service_identity to
security/py-service-identity

- Bump PORTREVISION for dependency change (except security/py-trustme)

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.

net-im/py-unmessage: Add missing dependencies

unmessage currently fails at runtime with the following errors:

1) pkg_resources.DistributionNotFound: The 'service_identity' distribution was
not found and is required by Twisted

unmessage depends on Twisted *and* its "tls" optional (extras_require)
dependencies, requiring unmessage to depend directly on them:

  - openssl
  - service_identity
  - idna

2) ImportError: No module named _sqlite3 (fixed by ports r512099)

Use PY_FLAVOR for dependencies.

FLAVOR is the current port's flavor, it should not be used outside of
this scope.

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

unMessage is a peer-to-peer instant messaging application designed to enhance
privacy and anonymity.

Features:

Transport makes use of Twisted, Tor Onion Services and txtorcon
Encryption is performed using the Double Ratchet Algorithm implemented in pyaxo
(using PyNaCl)
Authentication makes use of the Socialist Millionaire Protocol implemented in
Cryptully
Transport metadata is minimized by Tor and application metadata by the unMessage
protocol
User interfaces are created with Tkinter (graphical) and curses (command-line)
