6402556157 deinterlace: Port greedyl to GstDeinterlaceSimpleMethod 
The main goal of this change is to reuse the complex but now neatly
written scanline pointer calculation code from the simple methods.

6b26017ae7 deinterlace: small clean-ups 
Improve debug output by printing the buffer pointer when
popping a buffer and simplify code to use scanlines.bottom_field
as appropriate.

cb527623a3 deinterlace: Handle image caps without asserting 
Images might have framerate=0/1 in the caps, which caused an
assertion on deinterlace. I don't know of interlaced image formats
but deinterlace might be hardcoded on some generic pipelines and
it shouldn't assert.

The fix was to set field_duration to 0 if the input has a framerate
with a 0 numerator.

This patch also adds checks for this situation on the unit tests.

c2b343cd76 deinterlace: rewrite how neighboring scan lines are calculated 
Old code was difficult to understand exactly how the neighboring
scan lines are calculated, and it appeared that some were off by
+2 or -2, depending on the field flag.  Fixes #639321.

97d74f293c deinterlace: Change the default to linear 
The previous default, greedyh, takes 4 times as long as MPEG-2
video decoding, and is unlikely fast enough on any current CPU
to play 1080i video in real-time.  greedyl isn't much faster.
linear was chosen over vfir, since the quality advantage of vfir
is minimal compared to the occasional visual artifacts and slower
processing.

9be159b32c deinterlace: Implement field history flushing 
In a number of cases it is necessary to flush the field history by
performing 'degraded' deinterlacing - that is, using the user-chosen
method for as many fields as possible, then using vfir for as long as
there are >= 2 fields remaining in the history, then using linear for
the last field.

This should avoid losing fields being kept for history for example at
EOS.

This may address part of #633294

6a6f90e745 deinterlace: Fix required fields logic 
Both history_count and fields_required count from 1. As per the while loop
condition that follows this code, to perform the deinterlacing method, we need
history_count >= fields_required fields in the history. Therefore if we have
history_count < fields_required (not fields_required + 1), we need more fields.
