codecparsers: avoid libc math library
...
Instead of the libc ceil() and pow() machinery for double types, since the
library uses it for unsigned integers use a simple math function for for ceil
division and bit left shift for integer power of two.

h265bitwriter: Correct the all API to byte aligned.
...
In fact, all the h265 bit writer have byte aligned output. So we
change the API from bit size in unit to byte size, which is easy
to use.

codecparsers: bitwriter: Calculate PicSizeInCtbsY when writing slice header.
...
The slice->pps->PicWidthInCtbsY/PicHeightInCtbsY values are calculated when
we parse the slice header. But they are not calculated in bitwriter and so
may not have valid value when writing slice header.
