uti: Call into McKernel futex()

(1) Masquerade clv
(2) Fix timeout
(3) Let mcexec thread with the same tid as McKernel thread migrating
to Linux handles the migration request
(4) Call create_tracer() before creating proxy related objects

Prevent one CPU from getting chosen by concurrent forks
...
One CPU could be chosen by concurrent forks because CPU selection and
runq addition are not done atomicly. So this fix makes the two steps
atomic.

schedule(): hold runq lock for the entire duration of context switching
...
releasing the runq lock after loading page tables but before the actual
context switch can leave execution in an inconsistent if the current
process is descheduled from an IRQ between these two steps.
this patch holds the runq lock with IRQs disabled and makes the context
switch a single atomic operation.
