dvenc: fix 2x4x8 (interlaced) weight table
...
Since the decoder has been fixed to output something similar to
other implementations, the encoder weight table needed this fix.
Reference PSNR values on a progressive sequence (from tiny_psnr)
from a chained encoding and decoding:
Full progressive: stddev: 0.74 PSNR: 50.69 MAXDIFF: 19
Before: stddev: 1.43 PSNR: 44.97 MAXDIFF: 17
This patch: stddev: 0.76 PSNR: 50.44 MAXDIFF: 14

dvenc: do not call dsputil functions with stride not a multiple of 16
...
Allowing dsputil functions to assume the stride is a multiple of 16
even for smaller block sizes can simplify their implementation.
This appears to be the only place this guarantee is not met.

The new lowres support is limited to decoders where lowres decoding
