701d0eb185 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.

This avoids having to memmove the large parts of the array when inserting into

for a 30 second 44 kHz mono sample, on my machine.
