Address some credit2 issues. This patch series, along with the recent
changes to the cpupools interface, should address some of the strange
credit2 instability.

[PATCH 0 of 2] Scheduler: Implement yield for credit scheduler
As discussed in a previous e-mail, this patch series implements yield
for the credit scheduler. This allows a VM to actually yield (give up
the cpu to another VM) when it wants to. This has been shown to be
effective when used in the spinlock code to avoid wasting time
spinning when another vcpu is not currently scheduled.
