ef3ee8b7bb encoder: h264,h265: fix regression in offset count 
In commit dc35dafa a bug was introduced because I assumed that
GST_CLOCK_TIME_NONE is zero when is -1. This patch fixes that mistake.

68b9ab7818 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.

4259d1aec7 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.

d76d78cc8e libs: fix compiler warnings 
After setting the release flags, the compiler warns about a couple
initialized variables.

Also marked a couple of set variables as unused, because they are only
used for assertion.

619058b5b7 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.

55775c6203 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:
