ffe92ff9f0 Fix input buffer size check in adpcm_ea decoder. 
Unfortunately the output buffer size check assumes that the
input buffer is never over-consumed, thus this actually
also allowed to write outside the output buffer if "lucky".

cfff297d98 adpcm: Skip samples whose ssd calculation has wrapped around 
Wraparound in ssd is mainly avoided by subtracting the ssd of the
best node from all the others once it has grown large enough.

If using very large trellis sizes (e.g. -trellis 15), the frontier
is so large that the difference between the best and the worst is
large enough to cause wraparound, even if the ssd of the best one
is subtracted regularly.

When using -trellis 10 on a 30 second sample, this causes only a slight
slowdown, from 61 to 64 seconds.

78f9d35c9a adpcm: Only increment heap_pos after finding a good enough sample 
This increases the PSNR slightly (about 0.1 dB) for trellis sizes
below 8, and gives equal PSNR for sizes above that.

d764e3ece9 adpcm: Use a hash table to improve checking for duplicate samples 
This lowers the run time from 158 to 21 seconds, for -trellis 8
with a 30 second sample on my machine.

This requires 64 KB additional memory.

38b3bda18f adpcm: Replace any of the leaf nodes in the heap 
By not looking for the exactly largest node, we avoid an O(n) seek through
the leaf nodes. Just pick one (not the same one every time) and try replacing
that node with the new one.

For -trellis 8, this lowers the run time from 190 to 158 seconds,
for a 30 second 44 kHz mono sample, on my machine.

f82e8f3482 adpcm: Store the trellis nodes in a heap instead of a sorted array 
This avoids having to memmove the large parts of the array when inserting into
it.

For -trellis 8, this lowers the run time from 245 seconds to 190 seconds,
for a 30 second 44 kHz mono sample, on my machine.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

94d9633a32 Replace "signed short" typecast with "int16_t" as suggested by 
Mans Rullgard. Value at the right side is 16 bit length signed.
We can not know for sure that short is in fact 16 bits, even if
this virtually always is the case.
