Deprecate some ports using deprecated version of python

Reduce dependency on the python2 metaport

PR:		225752
Submitted by:	Yasuhiro KIMURA

Remove libintl.so.9 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

Remove ${PORTSDIR}/ from dependencies, categories d, e, f, and g.

Upgrade relevant ports to the latest releases.

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

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

- Convert ports from databases/ and deskutils/ to new USES=python

Approved by:	portmgr (implicit)

Convert the Python framework bits to USES=python.

Please use USES=python instead of USE_PYTHON.

  USE_PYTHON=yes becomes USES=python
  USE_PYTHON=2.7+ becomes USES=python:2.7+
  USE_PYTHON_BUILD=3.3 becomes USES=python:3.3,build
  ...

A new PYTHON_FEATURES variable was added, which enables certain features for a
port and replaces some knobs at the same time;

  PYTHON_FEATURES=distutils replaces USE_PYDISTUTILS
  PYTHON_FEATURES=autoplist replaces PYDISTUTILS_AUTOPLIST
  PYTHON_FEATURES=py3kplist replaces PYTHON_PY3K_PLIST_HACK

A couple ports added support for OPTIONS but forgot to add them to
OPTIONS_DEFINE.

Add NO_PYTHON knob to make lev@ a bit happier. Minor version update of tdb.

Explicitly disable gettext.

Usage of .pre.mk requires corresponding .post.mk

Add new port databases/ntdb - it's revised version of databases/tdb, used by
net/samba41 port.
