fftools/ffmpeg_dec: eliminate all remaining InputStream uses

Browse Source 
Previously, the demuxer would register decoder with the scheduler, using
InputStream as opaque, and pass the scheduling index to the decoder.

Now the registration is done by the decoder itself, using DecoderPriv as
opaque, and the scheduling index is returned to demuxer from dec_open().

decoder_thread() then no longer needs to be accessed from outside of
ffmpeg_dec and can be made static.
