NAKAMURA Gou bdc945cb34 mcexec: wait for the signal to be received 
The mcexec may send a signal to itself in order that the mcexec
terminates abnormally.
Generally, the signal is delivered to the thread which sent the signal.
In this case, the signal terminates the mcexec immediately.

However, if the signal is delivered to another thread,
the thread which sent the signal can call exit(3)
before the signal terminates the mcexec.

NAKAMURA Gou 069bb10a02 make mcexec ignore garbage request 
When a signal is forwarded from McKernel,
ioctl(MCEXEC_UP_WAIT_SYSCALL) may return EINTR error.
In this case, though no syscall request has been received,
the mcexec starts to process the syscall requst that is garbage.

NAKAMURA Gou f5b4057074 add vsyscall 
- getcpu() is not implemented. It will cause SIGILL.
- gettimeofday() and time() are implemented with syscall.

NAKAMURA Gou bbbc6e1570 add shared mapped file (in progress) 
implemented:
- Pages can be shared between maps.
- A change made to a map is written to the file, at munmap().

not yet implemented:
- VM operation during page IO execution.
  Because page IO is executed with VM's lock.
- Page IO, which does not change a file size with any case.
  When munmap() races with truncate(), the file size may be changed
  illegally.

NAKAMURA Gou bdc02bb687 refuse the write to a read-only memory 
It was able to change a read-only memory using a system call that
forwarded to host.

To fix this, when read-only mmap(), it places read-only vm_area in the
mcexec's space.
