deinterlace: greedy, improve quality
...
scanlines->m1 = same line of the previous field
scanlines->t0 = line above of the current field
scanlines->b0 = line below of the current field
scanlines->mp = same line of the next field
Deinterlacing a field weaved frame:
When deinterlacing the top field, the next bottom field is available
(part of the same frame). but when deinterlacing the bottom field,
the next top field (part of the next frame) is not available and
scanlines->mp equals NULL.
In this case it's better to use greedy algorithm using the prevous field
(twice) rather then linear interpolation of the current field.

deinterlace: Fix vfir 16-bit orc calculations
...
memcpy works in bytes, but orc works in items, so given that the size
arguments is in bytes, we need to divide by the pixel stride.

deinterlace: greedyh: Use _plane in _packed, fix planar formats
...
This greatly reduces code duplication. It also exposed the cause for
planar formats not being properly deinterlaced:
The planar path was missing the initial offset adjustment that the
packed path did to `L2` and `L2P` in the case of an even field, which
caused it to select the wrong weave lines every other field.
Add those offsets in `_plane`.
