softmmu/dirtylimit: Implement dirty page rate limit
Implement dirtyrate calculation periodically basing on
dirty-ring and throttle virtual CPU until it reachs the quota
dirty page rate given by user.
Introduce qmp commands "set-vcpu-dirty-limit",
"cancel-vcpu-dirty-limit", "query-vcpu-dirty-limit"
to enable, disable, query dirty page limit for virtual CPU.
Meanwhile, introduce corresponding hmp commands
"set_vcpu_dirty_limit", "cancel_vcpu_dirty_limit",
"info vcpu_dirty_limit" so the feature can be more usable.
"query-vcpu-dirty-limit" success depends on enabling dirty
page rate limit, so just add it to the list of skipped
command to ensure qmp-cmd-test run successfully.
