Fix C VP8 H+V MC functions which do two-dimensional 4/6-tap filters to not overread beyond their edges if the second filter is 4-tap, since the outer pixels aren't there anymore since 44002d83.

Do not emulate larger edges than we will actually use for this round of MC. Decoding goes from avg+SE 29.972+/-0.023sec to 29.856+/-0.023, i.e. 0.12sec or ~0.4% faster.

The PCM_DVD encoder would be left unused, as allcodecs.c properly declared it as being decoder-only, but it would still be built into the object file. Since there is no block of code to properly encode this PCM format, it's not a full codec. Signed-off-by: NMans Rullgard <mans@mansr.com>
