Vladimir Voroshilov c6cd525aa0 Decrease returning probe score for WAV demuxer to avoid
probe conflict between WAV and future ACT demuxer.
This is necessary because ACT has standard WAV header
at top of it's own.

Vladimir Voroshilov 3c3704d281 Fix MJPEG decoder for AMV files.
Since decoding is doing from the end and aligned by 16
previous code worked correctly only when picture height was dividable by 16,
otherwise it provides garbage in top lines and truncates bottom.
New code adjusts data[] pointers taking in account alignment issue.

Vladimir Voroshilov 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.
