Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

KVM changes include a MIPS patch and the testdev backend used by the
ARM kvm-unit-tests.  icount include the first part of reverse execution
and Sebastian Tanase's patches to slow down -icount execution to the
desired speed of the target.

v1->v2: fix dump_drift_info to print nothing outside icount mode,
        and to compile on 32-bit architectures

  cpu-exec: Print to console if the guest is late
  cpu-exec: Add sleeping algorithm
  icount: Add align option to icount
  icount: Add QemuOpts for icount
