...along with some manual patches for the remaining ones.

It will be useful in the upcoming transition to refcounted AVFrames.

Also reorder some other #include when applicable.

Ensures that the next frame decoded after seeking will be decoded as a
keyframe.

Fixes yesterday's merge of Kostya's fix for ticket #409.

In Musepack SV8 codec property tell the maximum nonzero band, but every
frame codes maximum band as a limit (i.e. strictly less than given value).
Synthesis also expects maximum nonzero band, so there's a need to convert
frame maximum band limit value.

This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.
