In preparation for upcoming mpers-related changes, split ipc.c into independent groups of parsers. * ipc_defs.h: New file. * ipc_msg.c: Likewise. * ipc_msgctl.c: Likewise. * ipc_sem.c: Likewise. * ipc_shm.c: Likewise. * ipc_shmctl.c: Likewise. * mq.c: Likewise. * print_mq_attr.c: Likewise. * print_msgbuf.c: Likewise. * ipc.c: Remove. (sys_mq_open, sys_mq_timedsend, sys_mq_timedreceive, sys_mq_notify, sys_mq_getsetattr): Move to mq.c. (sys_msgget, tprint_msgsnd, sys_msgsnd, tprint_msgrcv, sys_msgrcv): Move to ipc_msg.c. (sys_msgctl): Move to ipc_msgctl.c. (tprint_sembuf, tprint_sembuf_array, sys_semop, sys_semtimedop, sys_semget, syssemctl): Move to ipc_sem.c. (sys_shmget, sys_shmat, sys_shmdt): Move to ipc_shm.c. (sys_shmctl): Move to ipc_shmctl.c. (printmqattr): Move to print_mq_attr.c. (tprint_msgbuf): Move to print_msgbuf.c. (IPC_64, PRINTCTL): Move to ipc_defs.h. * defs.h (struct xlat resource_flags): New prototype. * Makefile.am (strace_SOURCES): Remove ipc.c. Add ipc_defs.h, mq.c, ipc_msg.c, ipc_msgctl.c, ipc_sem.c, ipc_shm.c, ipc_shmctl.c, print_mq_attr.c, and print_msgbuf.c.
