flashsv: replace bitstream description by a link to the specification
...
An official specification now exists and it is both more detailed and easier to
understand than the incomplete notes available here. Also remove ideas on how
to implement an encoder; these notes are already present in the encoder.

ARM: allow unaligned buffer in fixed-point NEON FFT4
...
This function is called with only 8-byte alignment from
imdct for size 16. The fft4 function is not called for
the larger FFT or MDCT sizes, so this has no impact on
typical uses.

dca: set AVCodecContext frame_size for DTS audio
...
Set the frame size when decoding DTS audio.
This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.
