* tests/stat64.test: New test.
* tests/Makefile.am (check_PROGRAMS): Replace stat32 with stat64.
(stat_CFLAGS): Rename to stat64_CFLAGS.
(TESTS): Replace stat32-v.test and stat64-v.test with stat64.test.
* tests/.gitignore: Replace stat32 with stat64.
Parametrize code from fstatat.c to support <asm/stat.h>
as an alternative to <sys/stat.h> and move it to a separate file.
* tests/statx.sh: New file, based on fstatat64.test.
* tests/fstatat64.test: Use it.
* tests/newfstatat.test: Likewise.
* tests/xstatx.c: New file, based on fstatat.c.
* tests/fstatat.c: Use it.
* tests/Makefile.am (EXTRA_DIST): Add statx.sh and xstatx.c.
* tests/fstatat64.c (FSTATAT_NAME): Change to TEST_SYSCALL_NAME.
* tests/newfstatat.c: Likewise.
For some ioctls, like from drm, the identification of the correct ioctl
is done by custom code. Specifying IOCTL_NUMBER_STOP_LOOKUP on
return of ioctl_decode_command_number() disables further calls to
ioctl_lookup().
* defs.h (IOCTL_NUMBER_UNKNOWN, IOCTL_NUMBER_HANDLED,
IOCTL_NUMBER_STOP_LOOKUP): Add macros representing ioctl number state
decoding.
* ioctl.c (SYS_FUNC(ioctl)): Skip ioctl_lookup() when
ioctl_decode_command_number() returns a value with
IOCTL_NUMBER_STOP_LOOKUP flag is set.

The syscall number of restart_syscall returned by the kernel in case
of ERESTART_RESTARTBLOCK is broken on x32 from the beginning, see
https://lkml.org/lkml/2015/11/30/790
Until that improves, skip the test on x32.
* tests/restart_syscall.c (main) [__x86_64__ && __ILP32__]: Return 77.
On x32, tcp->ext_arg is not initialized for i386 personality,
so tcp->u_arg has to be used instead.
* lseek.c (SYS_FUNC(lseek)) [X32]: Handle "current_personality == 1" case.
Some old kernel headers, Ubuntu 14.04 in particular, provide
<asm/stat.h> editions that are completely wrong for x32.
Workaround this issue by providing a replacement.
* linux/x86_64/asm_stat.h: New file.
* linux/x32/asm_stat.h: Likewise.
* Makefile.am (strace_SOURCES): Add them.
While -P option needs /proc to match descriptors, it does not use
/proc to match pathnames. As this test does not need descriptor
match, the /proc requirement can be safely lifted.
* tests/fstatat64.test: Lift /proc/self/fd/ requirement.
Move inclusion of arch specific files that define static functions to
the end of syscall.c.
* syscall.c (get_syscall_result_regs, get_error, getregs_old):
New forward declarations.
(arch_get_scno): Move forward.
Move inclusion of "get_scno.c", "get_syscall_args.c",
"get_syscall_result.c", "get_error.c", and "getregs_old.c"
to the end of file.
Apparently, there are only two types of instruction pointer printers
depending on the architecture: those that print a register that was
fetched earlier, and those that fetch a register themselves using upeek.
With this change, architectures of the first type have ARCH_PC_REG
defined in their arch_regs.c file, architectures of the first type
have ARCH_PC_PEEK_ADDR defined there, and the common code in syscall.c
uses these macros to print the instruction pointer.

Make get_syscall_result.c files more self-contained. While they are
