Made databases/ldb to depend on openldap-sasl-client, so it won't conflict with the corresponding requirement of net/samba4* ports.

This is routine update for the Samba supplimentary libraries, bumping them to the versions that commonly acceptable by recent Samba ports, in particular, samba44.

- 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:*.

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

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
  PYTHON_FEATURES=noegginfo replaces PYDISTUTILS_NOEGGINFO
  PYTHON_FEATURES=concurrent replaces PYTHON_CONCURRENT_INSTALL
  PYTHON_FEATURES=pythonprefix replaces USE_PYTHON_PREFIX

Some knobs have been deprecated and are to be removed in the near future:

  PYTHON_MASTER_SITES - use MASTER_SITE_PYTHON instead
  PYTHON_PKGNAMESUFFIX - use PYTHON_PKGNAMEPREFIX instead
  PYDISTUTILS_INSTALLNOSINGLE - deprecated without replacement

Some knobs have been removed completely:

  PYTHON_MASTER_SITE_SUBDIR
  PYTHON_DISTNAME
  PYTHON_WRKSRC

Several variables specific to the Python framework are no longer passed to the
build environment to avoid polluting dependency builds.

  PYTHON_VERSION is not passed to .MAKEFLAGS anymore
  PYTHON_DEFAULT_VERSION,
  PYTHON_DEFAULT_PORTVERSION and
  PYTHONBASE are not passed to the make environment anymore

The conversion required a couple of ports to be updated to fit the changes and
new requirements. Those included "bsd.python.mk" directly or contained checks
in places, for which the USES framework would fail to provide correct values.

Python modules directly using the upstream Python package (such as py-tkinter
or py-sqlite3) were updated to avoid using the now unnecessary and remmoved
knobs from "bsd.python.mk".
