Janne Grunau requested to merge janne/dav1d:fix124 into master Oct 28, 2018

Prevent decoding a frame with inconsistant sequence and frame headers. Fix #124 (closed). Fix negative size param in pixel_copy due to inconsistant sb128 state between frame header (parsed with sb128 == 0) and sequence header and frame decoding with sb128 == 1. Fix clusterfuzz-testcase-minimized-dav1d_fuzzer-5707479116152832. Credits to oss-fuzz.
