fo read position reaches end of scanout), we have some fudge for flip completion handling in the last lines of active scanout. Old code assumed the threshold to be 99% of active scanout height, a ballpark estimate which worked ok. Since we know since a while how to calculate the actual threshold from linebuffer size, lets make use of it to get a more accurate threshold. This completion path is still prone to some races in corner cases, especially on pre-AVIVO hardware, so document them a bit better in the code comments.
