uti: futex call function in mcctrl
...
Previously, futex code of McKerenl was called by mccontrol,
but there ware some problems with this method.
(Mainly, location of McKernel image on memory)
Call futex code in mcctrl instead of the one in McKernel image,
giving the following benefits:
1. Not relying on shared kernel virtual address space with Linux any more
2. The cpu id store / retrieve is not needed and resulting in the code

Reject "setfsuid: Specify mcexec tid when asking mcexec for fsuid"
...
This fix is rejected because it only makes the setfsuid test in ostest
pass and doesn't fix the other issues including the one in which file
I/O could be done with the old fsuid because an mcexec thread with an
arbitrary tid could handle the system-call offload request.
Explanation of the rejected fix:
setfsuid() proceeds as follows:
1. McKernel asks mcexec for __NR_setfsuid (set)
2. mcexec calls setfsuid, reports the id to McKernel
3. McKernel asks mcexec for __NR_setfsuid (get)
4. mcexec calls mcexec_getcred(), reports the id to Mckernel
5. McKernel sets proc->fsuid to the obtained value
tid of mcexec on the 2nd and 4th step could be different. So this
fix lets mcexec report its tid on the 2nd step and McKernel specify
it in the 3rd step.
