lib/igt_frame: Add support for analog frame comparison testing
This adds support for analog frame comparison check, as used in VGA.
Since VGA uses a DAC-ADC chain, its data cannot be expected to be pixel
perfect. Thus, it is impossible to uses a CRC check and full frames have
to be analyzed instead. Such an analysis is implemented, based on both
an absolute error threshold and a correlation with the expected error
trend for a DAC-ADC chain. It was tested with a couple encoders and
provides reliable error detection with few false positives.
