This change ensures that the linker can drop adpcm_data.o if no decoder
that actually uses anything from there is enabled.

This is to avoid unused variables warnings after the code for
the disabled encoders has been #if'ed away which will happen in
a subsequent commit.

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].

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,

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.

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().

Commit 003b5c800f introduced seeking in argo_asf,
but this was missed, leading to non-deterministic output.

Is incorrect behaviour. Was covering for an encoder bug where it produced frames
of the wrong size.
