This avoids a crash when the next slice is not a start slice and thus
pkt->data is still NULL.
This probably only happens with broken or unsupported files like
http://samples.mplayerhq.hu/real/multirate/JustaSpa1937_64kb.rm
that need further fixes, but keeping vst state consistent is still a good idea.

This adds a function pointer for forward MDCT to FFTContext and
initialises it with the existing C function.  ff_calc_mdct() is
changed to an inline function calling the selected version as
done for other fft/mdct functions.

can not be use on raw data read from a file.

At the moment, duration is mainly set from the metadata packet. If that is not
available, the fallback is checking the low 24 bits of the last packet. This is
not enough for files over 4,6 hours in length, so read all 32 bits instead.
