* modules/demux/dvdnav.c: menus navigation seems to be working ok now.

* modules/demux/dvdnav.c: restart the decoders on VTS change only, not CELL change.
* src/input/input_dec.c: fixed the pictures leak work-around.
   Wasn't working before because there always is at least one READY_PICTURE which is the last/currently displayed picture.

 Please test, it may have heavily broken playback of some files !!!

 (not writing); use VarBoolImpl instead to instanciate read/write variables.
 Bool variables can now be combined with VarNotBool and VarBoolAndBool
 (TODO: VarBoolOrBool)
* commands/cmd_show_window.hpp: the commands now call directly
  GenericWindow::show/hide, because the visibility variable of a
  window is a VarBool (so, read-only)
* commands/cmd_input.hpp: added Play and Pause commands
* parser/interpreter.cpp: beginning of support of boolean expressions,
 like "vlc.isSeekable and not vlc.isStopped" (operator precedence is
 not really well handled yet)
* src/vlcproc.*: new variables "vlc.isSeekable", "vlc.isStopped" and
 "vlc.isPaused"
* controls/ctrl_checkbox.cpp: the "state" variable of a checkbox is
  now a passive VarBool, so actions must be explicitely set with
  'action1="..." action2="..."' in the xml file
* removed src/vlcvars.* => "vlc.isMute" doesn't work any more
 (anyway it didn't work well...)
* theme/theme.xml: updated with the new VarBool behaviour

* modules/demux/dvdnav.c: added parsing of DVD style MRLs.
* modules/demux/ps.h: small cosmetic changes.

* modules/demux/dvdnav.c: some coding style butchery and added on-the-fly menus selection.

* configure.ac, modules/demux/Modules.am: added ps2, ts2 and dvdnav modules to the build system.
* modules/demux/demux2.c: added an "ffmpeg" shortcut for the ffmpeg/libavformat demuxer.

 Now vlc can read a TS with multiple programs and streams them as
 indepandant output (well you need the new TS demuxer so ...)
 (It is not well tested)

 Example: (lines are wrapped)
 ./vlc -I rc --sout-all /ts2:/home/fenrir/test.ts \
    --sout '#duplicate{dst="std{access=udp,mux=ts,url=239.255.13.13}", \
                       select="program=8501",\
                       dst="std{access=udp,mux=ts,url=239.255.13.14}", \
                       select="program=8506"}'

    + Set the window title upon startup.
    + Support for window resizing (requires libcaca 0.8).

 hack because of the way input_SetProgram works).

 selector[,selector] where 'selector' are from:
    * no-audio, noaudio, audio
    * no-video, novideo, video
    * no-spu,   nospu,   spu
    * es=num or es=num_start-num_end
    * prgm=num or prgm=num_start-num_end (you can also use program
    instead of prgm)
 It applies for the last dst. selector1,selector2 means selector1 and
selector2.
 Ex:
    vlc file --sout '#duplicate{dst="1� dst", select="selection for 1� dst",
dst="2� dst", dst="3� dst", select="selection for 3� dst" }'

    + More code cleanup. Thanks a lot to jlj for testing my changes.
    + Removed AddNativeMD5 and merged Bordelize() into DoShuffle().
    + Decrypt the SCI data in-place and shuffle it in the same loop.

  issues after reading a bad theme)
* x11/.*: removed the hack of storing pointers as window properties

 * dvdnav.c: begin of a dvdnav plugin. It's more to test that to be a real
 plugin for now. (a lot of design problems are raised with it).

* modules/control/http.c: fixed another mem leak.

* src/playlist/info.c: get rid of the #ifdef HAVE_VASPRINTF now that we have it in our small libc.
* modules/control/http.c: fixed parsing in uri_extract_value().

* modules/control/http.c: fixed gcc warning.

 * Updated documentation on playlist_Add* (they return a id, not the position)

 * Begin updating news for a 0.7.1

* modules/control/http.c: fixed a whole bunch of mem leaks.

* ALL: make sure newly created playlist_item_t are initialized properly.

* modules/stream_out/transcode.c: fixed segfault.

* src/input/demux.c: fixed small mem leak.

* modules/stream_out/transcode.c: fixed mem leak.

 * try to use valid xhtml

    + Merged redundant functions.
    + Unobfuscated and cleaned up many parts of the crypto code.
    + Added comments here and there.

and work done to allow for palettized rendering (by not expanding
inline colormap entries when RGB2).
