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

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.
