macallan 195f4ebf1c Add support for asynchronous drawing in vcons. 
This is not finished but good enough for others to play with, enable with
options VCONS_DRAW_ASYNC
With this all drawing operations will be posted to a ring buffer instead
of being run directly, and run by a kernel thread. This avoids having to wait
for drawing operations to finish with the kernel lock held ( to a degree at
least ) and scrolling a (slow) framebuffer console should not disrupt other
operations anymore.
Problems:
- we need to switch back to synchronous operations when panicing or entering
  ddb, also re-enable async drawing when leaving ddb
- there are still occasional glitches
tested on an SS20 with cg14 and cg6 for dumb and accelerated cases
