be6546a4ff vaapi_encode: Pass framerate parameters to driver 
Only do this when building for a recent VAAPI version - initial
driver implementations were confused about the interpretation of the
framerate field, but hopefully this will be consistent everywhere
once 0.40.0 is released.

2201c02e6d vaapi_h264: Enable VBR mode 
Default to using VBR when a target bitrate is set, unless the max rate
is also set and matches the target.  Changes to the Intel driver mean
that min_qp is also respected in this case, so set a codec default to
unset the value rather than using the current default inherited from
the MPEG-4 part 2 encoder.

eefa4b76ee vaapi_h264: Scale log2_max_pic_order_cnt_lsb with max_b_frames 
Before this change, it was possible to overflow pic_order_cnt_lsb and
generate a stream with invalid POC numbering.  This makes sure that
the field is large enough that a single IDR B* P sequence uses fewer
than half the available POC lsb values.

831274fba4 avcodec/flacdsp: Avoid undefined operations in non debug builds 
This fixes ubsan warnings in non debug builds by using unsigned operations

in debug builds the correct signed operations are retained so that overflows
(which should not occur in valid files and may indicate problems in the DSP code
or decoder) can be detected.

Alternatively they can be changed to unsigned unconditionally, then its
not possible though to detect overflows easily if someone wants to test
the DSP code for overflows.

The 2nd alternative would be to leave the code as it is and accept that
there are undefined operations in the DSP code and that ubsan output is
full of them in some cases.

Similar changes would be needed in some other DSP routines
