Fixes an issue in 6.1 when reading a corrupted file with -xerror would
exit with success. This specific issue is not present in master, but
this should generally be a more robust behaviour.

If the sBIT chunk size is invalid, we should print a more informative
error message rather than return an error and print nothing.

Indexed color images use three colors for sBIT, but the function
ff_png_get_nb_channels returns 1 in this case. We should avoid erroring
out on valid files in this scenario.
Regression since 84b454935f.

In intra-only mode, frameIntervalP is 0, which means the frame
data array is smaller than the number of surfaces.
Together with using the wrong size on deallocation of the
frame_data_array, this lead to a crash.

Fields under the segmentation switch are never reset on a new frame, and
retain the value from the previous frame. This bugs out a bunch of
hwaccel drivers when segmentation is disabled but update_map isn't
reset because they don't ignore values behind switches. This commit also
resets the temporal field, though it may not be required.
We also do this for vp8 [1] so this commit is just mirroring the vp8
logic.
This fixes an issue with certain samples [2] that causes blocky
artifacts with vaapi, d3d11va and cuda (and possibly others).
Mesa worked around [3] this by ignoring these fields if
segmentation.enabled is 0, but d3d11va still displays blocky artifacts.
