AVI demuxer fails to parse indexed xxpc (palette change) chunks

[matsp888]

The AVI demuxer (libavformat/avidec.c) fails to parse indexed xxpc (palette change) chunks, resulting in "stream_ptr out of bounds" error messages rather than switching the palette. The TOON.AVI file (from King's Quest VI) below contains indexed xxpc chunks, and it plays fine with Windows Media Player.
