if we need blending & rendering modules (fixes text messages which
   were missing sometimes)

* modules/mux/asf.c: MUX_GET_ADD_STREAM_WAIT == true. Seems even asfh can't send new headers after the stream started.

* Invalid HTML SUX !
* Table layout SUX !

* Update PO files

* First round of updates for the french l10n

* src/video_output/vout_subpictures.c: use p_vout->output instead of p_vout->render where necessary.

 * Defer nsviews untill the NSWindow is created. Hopefully fixes the VLC[25709] *** Assertion failure in -[NSViewHierarchyLock unlockTopMostReader], AppKit.subproj/NSViewHierarchyLock.m:428

* 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.
