NAKAMURA Gou 0942bf0ce0 make dkprintf() evaluate its parameters always 
Parameters of dkprintf() should be evaluated even if dkprintf() is
disabled.  Because this enables to find expression of parameter obsolete
and to avoid unnecessary compiler warnings such as "unused variable".

Masamichi Takagi ea02628f2b Add reboot and shutdown script for builtin-x86 
It decides the number of cores for McKernel by looking into the
"SHIMOS: CPU Status:" line of dmesg. It sets the amount of memory for
McKernel to one urth of the total memory obtained by "free -g".

Masamichi Takagi 19fa391d4f Implement vfork system call 
It's implemented by making it issue clone system call internally with
the arguments of (SIGCHLD, 0, 0, 0, 0). The feature in which the caller
of vfork blocks until the child issues exit/execve is not implemented.
Refer to #233.
