3cac899af9 Split the ADTS header decoder off of the ADTS parser.

7167bc94cb aacdec: Remove the warning about non-meaningful window transitions.
It created false positives on seeks and where the first frame is STOP or SHORT.
It failed to warn in illegal SHORT->LONG transitions. In general it created
much confusion and many junk bug reports from the users.
