avcodec: Constify AVCodecs
...
Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.

dpx: use aligned line starts
...
SMPTE 268M-2003 specifies that each line starts at a 4-bytes boundary.
Therefore, modify correspondingly the input buffer strides and size.
Partially fixes ticket #3692 : DLAD_8b_3c_big.dpx still has inverted
colors, which might be related to endianness.
