Fix various issues in cirrus-qemu and clean up.

Patch 1 fixes a long-standing, but apparently harmless, bug. Patches
2 and 3 make mode programming more reliable. Patch 4 cleans up after
patch 3.

This series makes cirrus-qemu more reliable at the cost of some higher
resolutions.

Testeded on qemu-i368.
