Check umove() return code

* bjm.c (sys_query_module): Print input parameters when entering
syscall.  Fix handling of syscall error.  Handle unlikely umove()
failures.
* ipc.c (tprint_msgrcv): New function.  Move part of msgrcv parser code
here, add check umove() return code.
(sys_msgsnd): Print msqid parameter as int instead of long.
(sys_msgrcv): Likewise.  Use tprint_msgrcv().
* process.c (print_affinitylist): Check umove() return code.
* sock.c (sock_ioctl): Handle unlikely umove() failure in the
SIOCGIFCONF parser.
