0f168344f1 avcodec/adpcm: Disable dead code
This change ensures that the linker can drop adpcm_data.o if no decoder

avcodec/adpcm_psx: always fetch next byte irregardless of flag
Even though all samples are meant to be zero (if flag == 0x07),
doesn't mean that they aren't there. See No$PSX docs [1].

avcodec/adpcm_ima_apm: remove old extradata format
Was added in error very early on, passing in only the required fields.
Later, the muxer and demuxer were changed to pass the entire APMState
struct as extradata.

Technically a breaking change, but this was only around for a *very* short
time before it was updated,

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.

avcodec/adpcm: refactor init/flush code
Most of the codecs just need everything zeroed. Those that don't
are either handled inline during decode, or pull state from
extradata.

Move state reset/init functionality into adpcm_flush(), and
invoke it from adpcm_decode_init().
