Fix guest resetting
Resetting guests used to be racy, deadlock-prone, or simply broken (for
SMP). This patch fixes the issues, following Marcelo's suggestion to
consolidate the reset activity in the I/O thread. All vcpus are cleanly
stopped before the emulated hardware is reset, and kvm_arch_cpu_reset is
introduced and invoked to ensure that non-boot cpus are put into the
right state on x86. Note that other arch may need to look into this
service as well to get SMP reset right.
Moreover, a safety check is added to pause/resume_all_threads to ensure
that they are only invoked in I/O thread context.
