a247ac640d 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.

e15371061d lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bump
They are not properly namespaced and not intended for public use.

494f868e93 avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channels
The decoders in this set either have a fixed channel count, or read it
from the bitstream, and thus do not require the channel count as
external information.

Fixes various regressions since
81503ac58a, which requires a valid channel
count for decoders which do not set this capability.
