Fixing dependent ports for libxine 1.2.0

[Juergen Lock]

Hi!

 libxine 1.2.0 is finally released and I found a lot of ports no
longer build with it. :(  I now have patches for most (and one of
them, multimedia/konverter is maintained by this list and a few
other are unmaintained; the other maintainers I just emailed off-list.)

 The update for the libxine port itself is here:

	http://people.freebsd.org/~nox/tmp/libxine-1.2.0.patch

 The patches for ports that depend on it are here:

	http://people.freebsd.org/~nox/tmp/libxine-1.2.0-ports-001.patch

 Some notes:

- multimedia/konverter seems to have long delays and redraw problems,
  was this also true with the old libxine?  It's also still for kde3
  and there are better alternatives (avidemux?) so I guess it's not
  that big of a loss...

- multimedia/phonon-xine refuses to use libxine 1.2.0 (recommends
  a downgrade of libxine), and seems to be no longer developed(?),
  so I guess we'll just have to leave it.

- multimedia/kaffeine runs after patching x11/kdelibs4's FindXine.cmake
  (thanx rakuco for that fix), but it only shows a green window at least
  with mp4 or ts files.  (avi files and audio still work.)  It seems the
  kaffeine developers have found this too and are now switching away
  from libxine in their git repo - so I guess we'll have a broken
  kaffeine at least until they release a new version.

- And some fixes I have only build-tested so far, help wanted...

 Thanx,
	Juergen
