* cbs_av1: Fix reading of overlong uvlc codesMark Thompson2018-12-221-18/+40
| | | | | | | | | | | | | | | | | The specification allows 2^32-1 to be encoded as any number of zeroes greater than 31, followed by a one. This previously failed because the trace code would overflow the array containing the string representation of the bits if there were more than 63 zeroes. Fix that by splitting the trace output into batches, and at the same time move it out of the default path. (While this seems likely to be a specification error, libaom does support it so we probably should as well.) From a test case by keval shah <skeval65@gmail.com>.
