COLO: Add 'x-colo-lost-heartbeat' command to trigger failover
We leave users to choose whatever heartbeat solution they want,
if the heartbeat is lost, or other errors they detect, they can use
experimental command 'x_colo_lost_heartbeat' to tell COLO to do failover,
COLO will do operations accordingly.
For example, if the command is sent to the Primary side,
the Primary side will exit COLO mode, does cleanup work,
and then, PVM will take over the service work. If sent to the Secondary side,
the Secondary side will run failover work, then takes over PVM's service work.

We add three new members to struct MigrationIncomingState,

related thread for secondary VM, 'migration_incoming_co' records the
original migration incoming coroutine.

Add a new migration state: MIGRATION_STATUS_COLO. Migration source side
enters this state after the first live migration successfully finished
if COLO is enabled by command 'migrate_set_capability x-colo on'.
We reuse migration thread, so the process of checkpointing will be handled
in migration thread.

qmp: add QMP interface "query-cpu-model-baseline"
Let's provide a standardized interface to baseline two CPU models, to
create a third, compatible one. This is especially helpful when two
CPU models are not identical, but a CPU model is required that is
guaranteed to run under both configurations, where the original models run.
"query-cpu-model-baseline" takes two CPU models and returns a third,
compatible model. The result will always be a static CPU model.

qmp: add QMP interface "query-cpu-model-comparison"
Let's provide a standardized interface to compare two CPU models.
"query-cpu-model-compare" takes two models and returns how they compare
in a specific configuration.
The result will give guarantees about runnability. E.g. if a CPU model A
is a subset of CPU model B, model A is guaranteed to run in configurations
where model B runs, but not the other way around (might or might not run).
Usually, CPU features or CPU generations are used to calculate the result.
If a model is not guaranteed to run in a certain environment (e.g.
incompatible), a compatible one can be created by "baselining" both models
(follow up patch).

trace: Avoid implicit bool->integer conversions
An explicit if/else is clearer than arithmetic assuming #true is 1,
while the compiler should be able to generate just as optimal code.
