interface!

input_InfoCategory.

- Coding Style
- Added SAP/SLP to transcode tabpage

* modules/packetizer/mpeg4video.c: oops

* include/input_ext-plugins.h: export input_DecodeBlock().
* modules/stream_out/display.c: simplifications.
* modules/stream_out/transcode.c: memset of sout_stream_sys_t.
* modules/packetizer/mpeg4video.c: not all containers provide a pts info, in which case we use the dts.

- Rework v4l and stream out interface code to use  VLC playlists as it should be used.
- Remove dead wood

 * show duration in playlist window if available

* share/http/admin/browse.html: hmmm, the browse feature was reenabled by mistake.

       packetizers running in the input thread. (Usefull with sout)

display some of these even when not "advanced"

- Removing obsolete files.

  CR_AVERAGE #define in input_clock.c (useful for PVR input)
* modules/codec/ffmpeg/encoder.c, modules/stream_out/transcode.c : fixes
  for older version of ffmpeg
* modules/stream_out/transrate/transrate.c : misc optimizations

        - open the codec after that p_context has been fully initialisated.
        (fix ASV1)

* modules/gui/wxwindows/menus.cpp: moved audio/video track menu to the top.

* modules/access/cdda.c: removed double ';'

* modules/gui/wxwindows/*: got rid of the Misc menu and moved everything in the Settings one.

        - added raw output support.(in a pure hack way but allow
        transcode{vcodec=I420} )

    - now vout are checked for release every 300ms
    - when *-es are triggered, all same es are unselect not only the
    last selected. (more intuitive) The only problems are that it's not
    possible to select again all ES, and the checkbox can show only one
    selected ES.

* modules/codec/ffmpeg/encoder.c: fixed compilation problem with ffmpeg 0.4.8

* modules/codec/ffmpeg/*: fixed the code to disable cpu features.

* modules/misc/dummy/input.c: use p_input->psz_demux = "vlc,none" to force the demux.
