in the kaa structure: markSync and waitMarker. The first, if set, returns a hardware-dependent marker number which can then be waited for with waitMarker. If markSync is absent (which is the case on all drivers currently), waitMarker must wait for idle on any given marker number. The intention is to allow for more parallelism when we get downloading from framebuffer, or more fine-grained idling. - Replace the KdMarkSync/KdCheckSync functions with kaaMarkSync and kaaWaitSync. These will need to be refined when KAA starts being smart about using them. Merge kpict.c into kasync.c since kasyn.c has all the rest of these fallback funcs. - Restructure all drivers to initialize a KaaInfo structure by hand rather than statically in dubious order. - Whack the i810 driver into shape in hopes that it'll work after this change (it certainly wouldn't have before this). Doesn't support my i845 though. - Make a new KXV helper to avoid duplicated code to fill the region with the necessary color key. Use it in i810 and mach64 (tested).
