Upgrade strace to 4.17.
Noteworthy changes in release 4.17 (2017-05-24)
===============================================
* Changes in command line syntax
* Syscall classes specified in -e trace= option now have % prefix (like
-e trace=%process). Old style class names without leading % are still
supported, but considered deprecated now.
* Improvements
* Optimized syscall filtering.
* Improved representation of timestamps.
* Enhanced decoding of sched_setattr syscall.
* Added -e trace=%stat option for tracing variants of stat syscall.
* Added -e trace=%lstat option for tracing variants of lstat syscall.
* Added -e trace=%fstat option for tracing variants of fstat and fstatat
syscalls.
* Added -e trace=%%stat option for tracing syscalls used for querying file
status information (stat, lstat, fstat, fstatat, statx, and their
variations).
* Added -e trace=%statfs option for tracing statfs, statfs64 and statvfs
syscalls.
* Added -e trace=%fstatfs option for tracing fstatfs, fstatfs64 and fstatvfs
syscalls.
* Added -e trace=%%statfs option for tracing syscalls used for querying file
system statistics information (statfs-like, fstatfs-like and ustat).
* Added -e trace=/regex option for filtering syscalls using regular
expressions.
* Added support for prepending of question mark before syscall qualification
in -e trace expressions in order to suppress error in case no syscalls
matched the provided qualification.
* Implemented decoding of signal mask in rt_sigreturn syscall on alpha, arc,
arm, avr32, bfin, cris, hppa, m68k, metag, microblaze, mips, nios2, or1k,
powerpc, powerpc64, riscv, sh, sh64, sparc, sparc64, tile, x86, and xtensa
architectures.
* Implemented decoding of statx syscall.
* Implemented decoding of NS_* ioctl commands.
* Implemented decoding of the remaining V4L2_BUF_TYPE_* types.
* Implemented decoding of VIDIOC_[SG]_TUNER ioctl commands.
* Implemented decoding of NLMSG_ERROR netlink messages.
* Improved decoding of BPF_PROG_ATTACH command of bpf syscall.
* Improved decoding of misplaced parts in DM_* ioctl commands.
* Updated lists of ioctl commands from Linux 4.11.
* Bug fixes
* Fixed decoding of flags argument of preadv2 and pwritev2 syscalls on x32.
* Fixed the number of arguments and tracing flags of alpha specific syscalls.
* Fixed decoding of old sigsuspend syscall on alpha, cris, mips, powerpc,
powerpc64, sh, sh64, sparc, and sparc64.
* Fixed decoding of sgetmask and ssetmask syscalls on 64-bit architectures.
* Fixed decoding of netlink messages received within struct msghdr.
* Worked around a bug in miscompiled aarch64 kernels leading to the 3rd
argument of sched_getattr syscall being not quite 32-bit.
* Fixed corner cases of printing inaccessible times argument of utimes
and futimesat syscalls.
Bug: N/A
Test: strace date

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.
