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.

d557ba84d6 exclude interpreter's segment from data region
When an interpreter is located on the lower address (e.g. 0x0),
the text region is included in data region.
A fix to avoid this.

413fe7b54a mcexec: add a interpreter invocation
When start a program which have a PT_INTERP segment
(dynamic linkaged program have a PT_INTERP segment),
start the interpreter indicated by the PT_INTERP segment.
