gst/asfdemux/: Some clean-ups and small fixes: rename asf_stream_context structure to

Browse source 
Original commit message from CVS:
* gst/asfdemux/asfheaders.h:
* gst/asfdemux/gstasfdemux.c: (gst_asf_demux_free_stream),
(gst_asf_demux_seek_index_lookup),
(gst_asf_demux_handle_seek_event), (gst_asf_demux_get_stream),
(gst_asf_demux_setup_pad), (gst_asf_demux_add_video_stream),
(gst_asf_demux_process_ext_content_desc),
(gst_asf_demux_process_file), (gst_asf_demux_descramble_segment),
(gst_asf_demux_push_buffer), (gst_asf_demux_process_chunk),
(gst_asf_demux_process_segment), (gst_asf_demux_handle_data):
* gst/asfdemux/gstasfdemux.h:
Some clean-ups and small fixes: rename asf_stream_context structure to
AsfStream; inline some three-line utility functions that are only used
once anyway and get rid of their associated helper structs; make debug
category global so that it is used by the debug statements in the other
file as well; simplify gst_asf_demux_get_stream(); fix accidental
implicit initialisation of stream->last_buffer_timestamp to 0, which
would lead to missing timestamps on the first buffer; put fourcc format
into video caps to make certain proprietary wmv decoders happy (for the
case of WMVA in particular); play_time is offset by preroll as well, so
fix overreporting of duration for some files.
