* Add ACCESS_SET_PRIVATE_ID_STATE to the list of every access plugin
* msg_Err -> msg_Warn for unimplemented Control queries

  + introduce a "TEXT" subpicture region type.
  + a psz_text field stores the subpicture text.
* src/video_output/video_text.c: produce "TEXT" subpictures.
* modules/codec/subsdec.c: produce "TEXT" subpictures.
* modules/misc/freetype.c: auto sizing works again.

* modules/audio_filter/converter/dtstofloat32.c,a52tofloat32.c,mpgatofixed32.c: release the old audio buffer after conversion.

* modules/codec/araw.c: got rid of the audio conversion in the encoder, which is now done by the audio filters.

* modules/audio_filter/converter/dtstofloat32.c,a52tofloat32.c: don't forget to update the size of the audio buffer after decoding.

* modules/demux/avi/avi.c: raw RGB 24 is in fact BGR 24.

* modules/mux/mpeg/ts.c: waiting for the fifo to have 51 packets before muxing is completely insane. Put back the old value of 2 packets.

i've modified the following functions to properly skip data (read buffer is nil) on streams which cannot be seeked.

AStreamReadBlock()
AStreamReadStream()

before those modifications, playback would suddenly be interrupted after a while on network streams prone to packet loss.

  remember to configure vlc with --with-ffmpeg-zlib

* the prime manage thread now runs every .1 sec instead of .3,
  this might improve response sometimes.

fix it... (it should be annoying only with TS, you may have dead program
entry).

has been cropped.

* Updated TODO list

* modules/stream_out/transcode.c: when overlaying subtitles, duplicate frames if they are referenced by the decoder.
