The Musepack decoder uses static VLC tables to parse the bitstream.
There are 14 different quant tables VLCs and each of them has a varying
number of codes. The maximum number is 63, the average number is 25.3.
Up until now, the array containing the raw data was of type
uint16_t [7][2][64 * 2] (the 14 tables come in pairs of two, hence [7][2]
instead of [14]) and from this it follows that there were large gaps in
said array. This commit changes this by making it a continuous array
instead. Doing so saves about 2KB.

The MobiClip decoder uses adjacent pixels for prediction; yet when
accessing the left pixel, it was forgotten to clip the x coordinate.
This results in an heap-buffer-overflow. It can e.g. be reproduced with
the sample from https://samples.ffmpeg.org/V-codecs/MOHD/crap.avi when
forcing the video decoder to mobiclip.

If allocating the tiles array for indeo 4/5 fails, the context is in an
inconsistent state, because the counter for the number of tiles is > 0.
This will lead to a segfault when freeing the tiles' substructures.
Fix this by setting the number of tiles to zero if the allocation was
unsuccessful.

The dsicinvideo decoder already has the FF_CODEC_CAP_INIT_CLEANUP flag
set, so it is unnecessary to directly clean up some already allocated
buffers in case another one could not be allocated in the init function,
as all buffers will be freed anyway later in the decoder's close
function.

Keeping only the latest packet fed to the decoder works only for decoders that
return a frame immediately after every consumed packet. Decoders that consume
several packets before they return a frame will fill said frame with properties
taken from the last consumed packet instead of the earliest.

SMPTE 12M timecode can only count frames up to 39, because the tens-of-frames
value is stored in 2 bit. In order to resolve this 50/60 fps SMPTE timecode is
using the field bit (which is the same bit as the phase correction bit) to
signal the least significant bit of a 50/60 fps timecode. See SMPTE ST
12-1:2014 section 12.1.
Therefore we slightly change the format of the return value of
av_timecode_get_smpte_from_framenum and AV_FRAME_DATA_S12M_TIMECODE and start
using the previously unused Phase Correction bit as Field bit. (As the SMPTE
standard suggests)
We add 50/60 fps support to av_timecode_get_smpte_from_framenum by calling the
recently added av_timecode_get_smpte function in it which already handles this
properly.
This change affects the decklink indev and the DV and MXF muxers. MXF has no
fate test for 50/60fps content, DV does, therefore the changes.
MediaInfo (a recent version) confirms that half-frame timecode must be inserted
to DV. MXFInspect confirms valid timecode insertion to the System Item of MXF
files. For MXF, also see EBU R122.
Note that for DV the field flag is not used because in the HDV specs (SMPTE
370M) it is still defined as biphase mark polarity correction flag. So it
should not matter that the DV muxer overrides the field bit.
