(expect some breakage).
* modules/video_filter/blend.c: new alpha-blending module.

* include/vlc_es.h: added b_packetized field to es_format_t to tell a decoder if the input elementary stream will be fed in complete frames.
* include/vlc_codec.h: added a b_need_packetized field to decoder_t that is used by a decoder to tell if it wants to be fed complete frames.
* modules/demux/ts.c, modules/demux/ps.h, src/input/input_programs.c: b_packetized = VLC_FALSE.
* modules/codec/ffmpeg/ffmpeg.c, modules/codec/faad.c: b_need_packetized = VLC_TRUE;
* src/input/input_dec.c: if (b_need_packetized & !b_packetized) then kick off a packetizer that we'll use to feed the decoder.
* src/input/es_out.c: removed useless stuff.

* include/vlc_es.h: s/es_format_Free/es_format_Clean.

* modules/demux/ogg.c: fixed memleak.
* modules/codec/flac.c: fixed memleak.
* include/vlc_es.h: es_format_Free().

* include/vlc_common.h, include/vlc_es.h: new video_palette_t structure.
* modules/codec/ffmpeg/*: support for palettized codecs.

 (I have no sample at all)

* include/input_ext-intf.h, include/vlc_es.h: moved ES categories into vlc_es.h
* modules/codec/lpcm.c: ported to the new decoders api + lpcm packetizer.

 all: removed i_extra_type from es_format_t.
