videoconvert: add additional width/height constraints
...
Some of the fastpath function can only work with aligned widht/height
so make sure we check this as well when choosing a fastpath.
Add fastpath for I420/YV12 -> BGRx

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.

just fine.

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.

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.
