The TXL Programming Language (transformation by example)

 TXL is a unique programming language specifically designed to support computer
software analysis and source transformation tasks. It is the evolving result
of more than fifteen years of concentrated research on rule-based structural
transformation as a paradigm for the rapid solution of complex computing
problems.

The TXL programming language is a hybrid functional / rule-based language with
unification, implied iteration and deep pattern match.

Each TXL program has two components:

 * A Description of the Structures to be Transformed
   Specified as an EBNF grammar, in context-free ambiguous form.
 
 * A Set of Structural Transformation Rules
   Specified by example, using pattern/replacement pairs.

Mega-patch to cleanup the ports infrastructure regarding our linux bits:
  - USE_LINUX now implies NO_FILTER_SHLIBS=yes. It also doesn't use FreeBSD
    tools to strip binaries anymore, so it's not neccesary anymore to override
    STRIP and STRIP_CMD.
  - USE_LINUX_PREFIX implies NO_MTREE now.
  - In the USE_LINUX case, USE_XLIB now depends upon the linux X11 libraries
    instead upon the native FreeBSD libraries.
  - The variable LINUX_BASE_PORT contains a string which is suitable as an
    item in *_DEPENDS, so if a port BATCH_DEPENDS or FETCH_DEPENDS upon the
    default (or overriden) linux base, ${LINUX_BASE_PORT} should be used
    instead of a hardcoded reference.
  - Change all ports to comply to the "new world order".
  - The Ports Collection now allows to override the default linux_base port.
    Specify e.g. OVERRIDE_LINUX_BASE_PORT=rh-9 in /etc/make.conf to use
    ${PORTSDIR}/emulators/linux_base-rh-9 (the logic is to use
    ${PORTSDIR}/emulators/linux_base-${OVERRIDE_LINUX_BASE_PORT}).
  - If USE_LINUX or OVERRIDE_LINUX_BASE doesn't point to an existing linux_base
    port and if USE_LINUX isn't set to "yes" (case insensitive), the port will
    be marked as IGNORE. [1]
  - Readd USE_LINUX knobs into several ports and make several uses of a
    conditional dependency ("USE_LINUX?=") into an unconditional one
    ("USE_LINUX=") which where removed/changed by Trevor to allow the use of
    alternative linux_base ports. While this is a nice goal, the implementation
    resulted in missing dependencies. The OVERRIDE_LINUX_BASE_PORT knob
    in this commit is supposed to fix the problem while keeping the feature.
    Basicaly this includes a backout of Trevor's commit, to prevent confusion
    I mention it here explicitely.
  - Use the correct prefix (X11- instead of LOCAL- or LINUX-) for some ports.
    Chase dependencies for this.
  - Changes to make linux_devtools installable on amd64, remove some stray
    device nodes (they don't work on recent OS versions and aren't really
    needed).
  - Make linux_base-8 PREFIX clean and remove some stray device nodes.
    Additionally tell a little bit more about how to setup NIS/YP [2].
  - Update the PGSQL dependency in the linux-opengroupware port to a recent
    version (the old one isn't available anymore), I don't know if this
    works (at least it isn't more broken than before).
  - Use PREFIX/usr/share/doc instead of PREFIX/usr/doc in the divx4linux
    ports, the former path exists already and gets populated by other
    packages too (PREFIX=LINUXPREFIX!).
  - Fix some obvious (non-linuxolator) bugs in some linux ports while being
    there.
  - Bump PORTREVISION where neccesary.
