22da49a55c videoconvert: also allocate temp lines in fastpath 
Some of the fastpath functions need tmplines, so make sure we allocate some in
the fastpath too.

This avoids SEGFAULTs with odd heights.

579be969e5 videoconvert: add more fastpaths 
Also reuse the I420 code for YV12 because it can handle the swapped UV fields
just fine.

10b3b88e9c videoconvert: fix handling of chroma resample 
Increase the number of temporary lines that we need, it is possible that the
up and downsampling offsets are out of phase and that we need to keep some
extra lines around. Also copy the unhandled output lines for the next round
instead of overwriting them.

701ae2f144 videoconvert: respect the pack_lines when packing 
Packing is supposed to happen on the amount of lines specified in the format
info. It's currently all set to 1 but that will change.

33a54ba4f3 videoconvert: be smarter when selecting a conversion 
Try to select the conversion that would result in the minimal amount of quality
loss. Quality loss is calculated rather arbitrarily but it avoids doing
something really stupid in most cases.

b1950b6409 Revert "videoconvert: prevent bad interlaced conversions" 
This reverts commit adc9694ed7.

No need to restrict the conversion, we can handle interlace correctly. We
basically unpack each field, then convert each field to the target colorspace
and pack and interleave each field to the target format. We also disable any
fast path that can't deal with interlaced formats.

adc9694ed7 videoconvert: prevent bad interlaced conversions
