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

Update cairo python bindings to 1.14.1.

* Update MASTER_SITE and WWW to point the new home
* Build from the same distfile
* Use python distutils to build the port instead of waf
* Drop stale MCom $Id
* Add license

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

Let gnome3 stack be built with python 3.5

This mostly fixing packaging for python3.5, but there is
also py35 waf fix for py3-cairo, that was obtained from Ubuntu
repository.

Improve shebangfix framework

- Support multiple values in *_OLD_CMD, i.e. we can now fix both
"/usr/bin/python" and "/usr/bin/env python" at the same time
- Default *_OLD_CMD values are now always appended, so you don't need to specify
them in individual ports
- Add lua support (depends on USES=lua)
- Add more default values, such as "/usr/bin/env foo" for python, perl, bash,
ruby and lua
- Shebangfix now matches whole words, e.g. we will no longer (erroneously)
replace "/usr/bin/perl5.005" with "${perl_CMD}5.005" (but "/usr/bin/perl -tt" is
still (correctly) replaced with "${perl_CMD} -tt")

Note that *_OLD_CMD items containing spaces must now be quoted (e.g.
perl_OLD_CMD=/bin/perl /usr/bin/perl "/usr/bin/env perl")

Update shebangfix usage according to new rules in many ports:

- Remove *_OLD_CMD for patterns now replaced by default
- Quote custom *_OLD_CMD which contain spaces

Fix shebangfix usage in many ports (irrelevant to infrastructure change):

- Remove redundant SHEBANG_LANG (no need to duplicate default langs)
- Remove redundant *_CMD (such as
python_CMD=${LOCALBASE}/bin/python${PYTHON_VER} when USES=python is present)
- Never use *_OLD_CMD in REINPLACE_CMD matchers, these should always look for
exact string

Add a new USES=waf to handle the waf building system, allowing to factorise code
Plug waf into MAKE_CMD and CONFIGURE_CMD so the regular defined targets can be
reused

Always define _MAKE_JOBS so that when bsd.port.mk will stop overwritting
_MAKE_JOBS when parallel jobs are disabled we can enforce -j1 (which is needed
to really disable parallelisation with waf

WAF_CMD has been created to allow one to override the location of the waf script
relatively to WRKSRC

CONFIGURE_TARGET is by default defined to "configure"
ALL_TARGET is by default defined to "build"
INSTALL_TARGET is by default defined to "install"

USES=waf is by default stagedir safe

Switch default python3 version from 3.3 to 3.4.

Cleanup plist

Don't hardcode python version.

Rework python module compile so it doesn't code the stagedir in it [1]

While here switch to USES=tar:bzip2
Remove waf from SHEBANG_FILES. it contains binary so running sed on it
 not guaranteed to work as intended. [2]
Prefix waf commands with PYTHON_CMD so it run with the correct python version.
Use the waf --destdir command for destdir
Remove configure_ENV because they are already set.
Use post-patch to dynamicly fix the python version in test/examples_test.py
 instead of a patch.

Do what was clearly intended: s/${ENV}/${SETENV}/

Prior to this change these ports fail when built under su(8) since that
results in ${ENV} being ~/.shrc.

Add forgotten NO_STAGE keyword.

Disable stage for now until I can figure out how to make it work with waf.
