HEVC frames can be encoded in multiple slices. This short series add
supports for them. First patch adds slice_segment_address to HEVC slice
parameters and second patch implements HEVC multi slice support in
Cedrus.

Question 1: HEVC specs talk about slice_segment_address, but "slice_"
prefix seems redundant in our case, because this field is part of slice
params structure. Should I drop it or leave it?

Question 2: I made slice_segment_address __u32 but __u16 might be
already enough. Which one should it be?

Note: These patches depends on following pull request:
