Unify usage of #include guards This commit is an attempt to unify usage of include guards (in top-level headers, at least). As a side note, different files with *.h extension have different semantics: for example, printargs.h is included multiple times in order to generate slightly varying code depending on values of macro definitions - maybe it's better to change extension of such files to something like *.inc. * defs.h: Add #include guard. * flock.h: Likewise. * ipc_defs.h: Likewise. * mpers_type.h: Likewise. * printsiginfo.h: Likewise. * ptrace.h: Likewise. * regs.h: Likewise. * seccomp_fprog.h: Likewise. * gcc_compat.h: Rename the macro used for #include guard. * msghdr.h: Likewise. * sigevent.h: Likewise. * kernel_types.h: Comment the trailing part of #include guard. * xlat.h: Add missing macro definition for #include guard.

Support C libraries without System V shared memory/ipc Some systems (like Bionic) omit support for SysV related code. That means no C library headers for strace to include. Add configure tests to probe the headers from the kernel and use them when they are available. It might make more sense to never rely on the C library's headers as there is no guarantee or requirement that the structure layout between apps and the C library match that what is passed to the kernel. * configure.ac (AC_CHECK_HEADERS): Check for linux/ipc.h, linux/mqueue.h, linux/msg.h, linux/sem.h, linux/shm.h, sys/ipc.h, sys/msg.h, sys/sem.h, and sys/shm.h. * ipc_defs.h: Include <sys/ipc.h> or <linux/ipc.h> depending on what is available. * ipc_msg.c: Replace <sys/ipc.h> with "ipc_defs.h". Fallback to <linux/msg.h> when available. * ipc_msgctl.c: Include <sys/msg.h>, <asm/msgbuf.h>, or <linux/msg.h> based on what is available. Note missing support for old ipc structs. * ipc_sem.c: Include <sys/sem.h> or <linux/sem.h> depending on what is available. Only decode sembuf when available. * ipc_shm.c: Fallback to <linux/shm.h> when available. * ipc_shmctl.c: Include <sys/shm.h>, <asm/shmbuf.h>, or <linux/shm.h> based on what is available. Note missing support for old ipc structs. * print_mq_attr.c: Fallback to <linux/mqueue.h> when available.
