Add IPC functions based on shared memory.

shmget(), shmat(), shmdt(), shmctl() in kernel/shm
sample app is located at application/shm
shared memory is allocated by buddy algorithm.
shared memory area is as following. (cf, include/knl/arch.h)
define IPC_START_OFFSET (APP_START_OFFSET + APP_SIZE)

define IPC_SIZE ((unsigned long) (512<<20)) // 512MB
