Changeset r5636 changed the timers to run in the alarm callback.  The 
alarm callback can only be called as frequently as the host alarm timer 
fires.  For older Linux hosts and possibly non-Linux hosts, this can be 
as high as a 1ms granularity.

icount calculates the select timeout based on the next deadline and 
select is usually capable of sleeping for a short period of time than 
alarm timer granularity.  This means that changing the timer callbacks 
to be based on alarm firing caused timers to fire much later than they 
ought to when using icount.

Hypervisors like KVM perform badly while doing mmio on
a loop, because it'll generate an exit on each access.
This is the case with VGA, which results in very bad
performance.

In this patch, we map the linear frame buffer as RAM,
make sure it has dirty region tracking enabled, and then
just let the region to be written.

We select regions based on its start address, a

The main user of this interface right now is VGA optimization
