gst/flv/: Introduce demuxing support for AAC and

Browse source 
Original commit message from CVS:
2008-06-14  Julien Moutte  <julien@fluendo.com>

* gst/flv/gstflvdemux.c: (gst_flv_demux_cleanup),
(gst_flv_demux_dispose):
* gst/flv/gstflvdemux.h:
* gst/flv/gstflvparse.c: (gst_flv_parse_audio_negotiate),
(gst_flv_parse_tag_audio), (gst_flv_parse_video_negotiate),
(gst_flv_parse_tag_video): Introduce demuxing support for AAC
and
H.264/AVC inside FLV.
* sys/dshowdecwrapper/gstdshowaudiodec.c:
(gst_dshowaudiodec_init),
(gst_dshowaudiodec_chain), (gst_dshowaudiodec_push_buffer),
(gst_dshowaudiodec_sink_event), (gst_dshowaudiodec_setup_graph):
* sys/dshowdecwrapper/gstdshowaudiodec.h:
* sys/dshowdecwrapper/gstdshowvideodec.c:
(gst_dshowvideodec_init),
(gst_dshowvideodec_sink_event), (gst_dshowvideodec_chain),
(gst_dshowvideodec_push_buffer),
(gst_dshowvideodec_src_getcaps):
* sys/dshowdecwrapper/gstdshowvideodec.h: Lot of random fixes
to improve stability (ref counting, safety checks...)
