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.

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.
