encoder: h264,h265,mpeg2,vp8: use gst_util_uint64_scale() for bitrate
...
Use gst_util_uint64_scale() to calculate bitrate instead of normal arithmetic
to avoid overflows, underflows and loss of precision.

vaapiencode: h264,h265: validate fps numerator
...
Validate that fps numerator is non-zero so it can be used to calculate
the duration of the B frame.
Also it gst_util_uint64_scale() is used instead of normal arithmetic in
order to aviod overflows, underflows and loss of precision.

encoder: hevc: Fix the size over-flow for encoded buffer.
...
The approximation of 6 times compression ratio migh not
work in all cases. Especially when enabling I frames.
Provide large enough size for coded-buffer creation.

encoder: hevc: fix bug in multi slice encoding.
...
This is a work-around for satisfying the VA-Intel driver.
The driver only support slices begin from CTU row start address.
Multi-Slice encoding also requires a fix in va-intel-driver:
