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
  current python flavor.  It can be used in dependency lines when the
  port itself is not python flavored.  For example, deskutils/calibre.

  By default, all the flavors are generated.  To only generate flavors
  for the versions in PYTHON2_DEFAULT and PYTHON3_DEFAULT, define
  BUILD_DEFAULT_PYTHON_FLAVORS in your make.conf.

  In all the ports with Python dependencies, the *_DEPENDS entries MUST
  end with the flavor so that the framework knows which to build/use.
  This is done by appending '@${PY_FLAVOR}' after the origin (or
  @${FLAVOR} if in a Python module with Python flavors, as the content
  will be the same).  For example:

    RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

Add more PLIST_SUB to Mk/Uses/python.mk

- Add PYTHON_PYOEXTENSION and PYTHON_SUFFIX
- Add PYTHON2 and PYTHON3
- Respect PYTHON_VERSION
- Rename PYOEXTENSION to PYTHON_PYOEXTENSION

This change would help:
- Build databases/postgresql*-plpython with Python 3
  (It has PLIST issue since bsd.python.mk to Uses/python.mk transition)
- Simplify Makefile

accessibility/speech-dispatcher: update to 0.8.6 - Fix paths in modules configuration - Improve Python slave port

Updates since 0.8.3:
* Implement a shutdown timer in the server, which activates after 5
  seconds with no clients connected
* Add support for espeak-ng (no FreeBSD port available)
* Add command-line argument to allow for custom modules location

accessibility/py3-speech-dispatcher: fix packaging with python 3.5

While here add NO_ARCH and make couple of whitespace fixes.

Split off the python bindings into it own slave port. They where not build by default and orca requires the bindings. Bump port revision just to be sure there will be no conflicts.
