93866c2aa2 intmath: remove av_ctz. 
It's a non-installed header and only used in one place (flacenc).
Since ff_ctz is static inline, it's fine to use that instead.

2469ed32c8 avcodec/flacenc: Fix Invalid Rice order 
Fixes ticket #4628.

The problem arose, in the sample file at least, in the last block where the
minimum and maximum Rice partition orders were both 0. In that case, and any
other where pmax == pmin, the original UINT32_MAX placeholder value for
bits[opt_porder] was getting overwritten before the comparison to check if the
current partition order is a new optimal, so the correct partition order and
RiceContext params were not being set.
