gst/mxf/: Add mxf_metadata_generic_sound_essence_descriptor_set_caps() to set rate and channels and use this for all ...

Browse source 
Original commit message from CVS:
* gst/mxf/mxfaes-bwf.c: (mxf_bwf_create_caps),
(mxf_aes3_create_caps):
* gst/mxf/mxfalaw.c: (mxf_alaw_create_caps):
* gst/mxf/mxfd10.c: (mxf_d10_create_caps):
* gst/mxf/mxfdemux.c:
* gst/mxf/mxfmetadata.c: (mxf_metadata_source_package_resolve),
(mxf_metadata_generic_picture_essence_descriptor_set_caps),
(mxf_metadata_generic_sound_essence_descriptor_set_caps):
* gst/mxf/mxfmetadata.h:
* gst/mxf/mxfmpeg.c: (mxf_mpeg_es_create_caps):
Add mxf_metadata_generic_sound_essence_descriptor_set_caps() to
set rate and channels and use this for all sound essence.
Give some debug output when setting picture essence caps with
invalid descriptor values.
Fix height calculation from the frame layout a bit more and
add a TODO to check if it's really correct now or if it needs
more fixing (especially, does the framerate need adjustments?).
