Add support for the third loop filter mode V4L2_MPEG_VIDEO_H264_LOOP_FILTER_MODE_DISABLED_AT_SLICE_BOUNDARY, and fix V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA and V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_BETA controls. The filter offset controls are signed values in the -6 to 6 range and are stored into the slice header fields slice_alpha_c0_offset_div2 and slice_beta_offset_div2. The actual filter offsets FilterOffsetA/B are double their value, in range of -12 to 12. Rename variables to more closely match the nomenclature in the H.264 specification.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
