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

mcctrl: convert perf ctrl ioctls to mcctrl_ihk_send_wait
...
While we are here, also optimize code a bit: perf_desc does not need
to be allocated for every cpu; and fix coding style.

mcctrl: refactor prepare_image into new generic ikc send&wait
...
Many ikc messages expecting a reply use wait_event_interruptible
incorrectly, freeing memory that could still be used on the other side.
This commit implements a generic ikc send and wait helper that helps
with memory management and ownership properly:
- if the message succeeds and a reply comes back normally, the memory
is freed by the caller as usual
- if the wait fails (signal before the reply comes or timeout) then the
memory is set as owner by ikc and will be free when the reply comes back
later
- if the reply never comes, the memory is freed at shutdown when
destroying ikc channels

mcexec: Add --stack-premap=<premap_size>[,<max>]
...
<premap_size> of stack is pre-mapped on creating a process.
And its max size of stack is set to <max>.
This replaces MCKERNEL_RLIMIT_STACK=<premap_size>,<max>.
