Make av1_ceil_log2 work for full range of int type

The current implementation of av1_ceil_log2() gets into an infinite loop
if the input is greater than 2^30. Fix this bug by judicious use of the
unsigned int type.

It would be better to define av1_ceil_log2(n) as get_msb(n - 1) + 1
because get_msb() has optimized implementations.
