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.

a80d11cde5 prevents MCKERNEL_RLIMIT_STACK from overwriting 
When mcexec reduces a stack, mcexec stores the original RLIMIT_STACK
in environment variable MCKERNEL_RLIMIT_STACK.
A fix to prohibit overwrite of this time.

Therefore, the value of RLIMIT_STACK of the McKernel's process is
decided in the following order.
(1) If environment variable MCKERNEL_RLIMIT_STACK exists; the value.
(2) A value of RLIMIT_STACK in the mcexec starting.

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.

603ef85454 mcexec: add a upper limit of the stack size 
- When the stack size is greater than 1 GiB, reduced to 10 MiB.
- To achieve a reduction of the stack, restart itself using the exec().
- By using the environment variable MCKERNEL_RLIMIT_STACK,
  tell to McKernel the stack size of the original.

MCKERNEL_RLIMIT_STACK is a environment variable which
specify RLIMIT_STACK value on McKernel.

example: MCKERNEL_RLIMIT_STACK=0x800000,-1

bc173baf13 mcexec: add a path prefix for interpreter search 
- When the interpreter is not found,
  add a prefix to the path and retry search.
- the prefix is specified by a environment variable MCEXEC_ALT_ROOT.
- If the MCEXEC_ALT_ROOT does not exist,
  /usr/linux-k1om-4.7/linux-k1om is used as a prefix.
