44deb9f68d mfxdec: Separate mxf_essence_container_uls for audio and video. 
It is a really bad idea to assign a video codec id
when we have set codec_type to audio and vice versa.

Prevents detection of mp2 in mxf as mpeg2video.

775d3b4ab1 mxfdec: Speed up metadata and index parsing. 
Specifically, this means parsing as before until we run into essence.
At that point we seek to the footer and parse until EOF. After that we start
seeking backward to the previous partition and parse that until we run into
essence or the next partition. This procedure is repeated until we encounter
the last partition we parsed in the forward direction.

The end result of all this is that large essence containers are not needlessly
parsed. This speeds up parsing large files a lot.

0999151962 mxfdec: Make sure DataDefinition is consistent between material track and source track. 
This fixes 0001GL.MXF.V1.mxf_opatom.mxf and 0001GL00.MXF.A1.mxf_opatom.mxf
getting two streams each due to both using the same SourcePackageID.

84ad31ff18 lavf: replace av_new_stream->avformat_new_stream part II. 
Manual replacements are done in this commit.

In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.

b7effd4e83 avio: avio_ prefixes for get_* functions 
In the name of consistency:
get_byte           -> avio_r8
get_<type>         -> avio_r<type>
get_buffer         -> avio_read

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return
something useful.

39bb30f664 Change all functions referenced in the mxf_metadata_read_table to use the same 
prototype and also always call them with exactly those arguments.
The previous way seems to have worked on all supported platforms, however
it was not strictly valid C and would crash e.g. with a compiler that
uses stdcall by default.
Also avoids warnings if -Wstrict-prototypes is used.
