to match libdrm and mesa identification.

vebox: silence compilation warning.

Silence the following compilation warning:
  CC     i965_drv_video_la-gen75_vpp_vebox.lo
gen75_vpp_vebox.c: In function 'bdw_veb_dndi_iecp_command':
gen75_vpp_vebox.c:1537:5: warning: suggest parentheses around arithmetic in operand of '|' [-Wparentheses]

Also simplify the calculation of the VEB_DI_IECP::endingX variable
with existing helper macros.

vebox: drop magic numbers in filters mask.

vebox: fix indication of field ordering in sequence.

VEBOX_DNDI_STATE::dndi_top_first indicates whether the top field is
first in sequence (TFF), or if the bottom field comes first. This is
an indication of the temporal sequence for input frames, available
in the "history" buffer. As such, the correct flag to check against,
from a VA-API perspective, is VA_DEINTERLACING_BOTTOM_FIELD_FIRST.

vebox: fix order of submitted commands.

For each frame, the Intel HD Graphics hardware specification mandates
that the following commands should be submitted, in-order: VEBOX_STATE,
VEBOX_SURFACE_STATE(input), VEBOX_SURFACE_STATE(output), VEB_DI_IECP.

vebox: fix invalid conversion and scaling params order.

The arguments to vpp_surface_convert() were mixed up. i.e. both input
and output surfaces were reversed. Changed the vpp_surface_scaling()
arguments order as well to have more consistent helper functions.

vebox: clean-up frame store initialization.

Rename FRAME_STORE_SUM to FRAME_STORE_COUNT, use existing macros to
determine the number of elements in the frame store array, avoid
duplicate zero initializations.

vebox: factor out initialization of pipeline parameters.

Factor out initialization and validation of pipeline parameters.
In particular, introduce a new gen75_vebox_init_pipe_params() helper
function that initializes the filters mask and ensures the supplied
filters are going to be supported.

vebox: robustify frame store surface storage allocations.

Clean-up frame store surface storage allocation, rename the helper
function to gen75_vebox_ensure_surfaces_storage() and make it more
robust to allocation errors. i.e. propagate them up right away.

vebox: factor out deinterlacing code.

Completely rework the VEBOX code to factor out and improve the various
deinterlacing algorithms in particular. Introduce temporary variables
that are going to be live for the current VPP processing call.

Drop MADI/MCDI support for now.

Initial focus was to definitively fix first vs. second field detection
code, thus allowing more multiple VEBOX calls with an additional format
conversion away.

vebox: add support for advanced deinterlacing.

Reintegrate Motion Adaptive Deinterlacing (MADI) and Motion Compensated
Deinterlacing (MCDI) support. This is totally reworked so that to allow
for bob-deinterlacing if no previous frame was supplied, improve global
robustness, and ensure that the right surface storage are used.

vebox: fix denoising when IECP is enabled.

If IECP is enabled, for instance when color conversion is performed
or ProcAmp adjustments are applied, the ultimate denoised output with
additional processing operations applied is the Current Output frame,
not the plain Current Denoised Output frame.
