Zach Reizner 6a8fdd9f8e crosvm: add suspend/resume commands ... This change adds the suspend and resume commands to crosvm, as well as corresponding VmRequest variants and VCPU loop support. When a request triggers a VmRunMode change, the Mutex guarded shared VmRunMode variable is mutated and the associated Condvar is notified. Each VCPU thread is interrupted to kick it out of the KVM_RUN call and checks the VmRunMode, If the VCPU was already suspended by waiting for the Condvar, the notify_all call will wake up the thread, upon which the VCPU thread can respond to the new mode.
