Newer Linux architectures don't support the stat/stat64 syscalls.
Instead they use fstatat() with AT_FDCWD and an extra flags argument.
Support seeing this output in the 'strace -efile' test.
As part of this change, use "grep -E -x" syntax consistently for
all stat tests, since the number of \(foo\)\? expressions was becoming
pretty unwieldy.
* tests/stat: Update stat/stat64 check regexp to handle architectures
that use fstatat instead. Use "grep -E -x" syntax consistently.

ARM OABI and ARM EABI have different function parameters passing rules,
see commit v4.6-11-g7a5b08f for details.
* util.c (printllval): Do not align argument number in case of ARM OABI.
* file.c (sys_fadvise64_64): Likewise.
The mips/o32 ABI and xtensa arch also do 64bit aligning, so add it to the
printllval list for this.
Normally for sys_fadvise64_64 we'd handle the same list of arches, but
mips/o32 ABI is funky and doesn't shift -- it has 7 args. So just add
xtensa to it.
* file.c (sys_fadvise64_64): Add XTENSA to the shifted list.
* util.c (printllval): Add LINUX_MIPSO32 and XTENSA to the shifted list.
The tile arch just has the dedicated syscalls, so disable
the logic for parsing subcalls.
* linux/syscall.h [TILE]: Do not define SYS_socket_subcall and
SYS_ipc_subcall.

The Blackfin arch does not have a socketcall or ipc subcall
(it has dedicated syscalls broken out), so disable the logic for it.
* linux/syscall.h [BFIN]: Do not define SYS_socket_subcall and
SYS_ipc_subcall.
Since the length fields with the ubi volnames are signed 16bit values,
make sure we clamp that number to the size of the buffer we've allocated
on the stack to prevent buffer overflows.
* mtd.c (ubi_ioctl): Clamp length to string_quote to 0/UBI_MAX_VOLUME_NAME.
Check the return of string_quote and tweak the output accordingly.
Been playing with UBI of late and it'd help if I could see what it was
doing. Not entirely sure about the decoding of UBI_IOCVOLUP -- it takes
a pointer to a 64bit value, not a strict.
* util.c (MAX, MIN): Move to ...
* defs.h (MAX, MIN): ... here.
(CLAMP): Define.
(ubi_ioctl): New prototype.
* ioctl.c (ioctl_decode): Call ubi_ioctl when code is 'o' or 'O'.
* mtd.c: Include ubi user API header.
(ubi_volume_types): New enum decode.
(ubi_volume_props): Likewise.
(ubi_ioctl): Define.
* linux/ubi-user.h: Import from linux 3.8.
I used these to develop the mtd/ubi ioctl decoders.
* test/.gitignore: Add mtd/ubi.
* test/Makefile: Declare all tests in a PROGS var.
Declare build targets .PHONY.
(all): Depend on $(PROGS) instead of hardcoded list.
(clean): Remove $(PROGS) instead of hardcoded list.
* test/mtd.c: New file.
* test/ubi.c: Likewise.
These funcs use things like wait/write/read/strcmp but sometimes
don't include the right header for them.
* test/Makefile: Add -Wall to CFLAGS.
* test/clone.c: Include unistd.h.
* test/fork.c: Include sys/wait.h.
* test/sig.c: Include unistd.h.
* test/sigkill_rain.c: Include sys/wait.h.
* test/vfork.c: Include sys/wait.h.
* test/wait_must_be_interruptible.c: Include string.h
* linux/ia64/syscallent.h: Undefine sys_oldlstat, sys_lstat and
sys_lstat64 before redefining them to printargs.

* desc.c (printflock) [X32]: Add special handling required for
this architecture with sizeof(long) < sizeof(off_t).
* file.c [X32] (struct stat64): Add __attribute__((packed)).
[X32] (HAVE_STAT64): Define.
(printstat) [X32]: Redirect to printstat64.
(printstat64) [X32]: Use "struct stat" instead of "struct stat64".
[X32] (realprintstat64): Rename to printstat64_x32.
(sys_stat64, sys_fstat64) [X32]: Remove second definitions of these
functions. Call printstat64_x32 instead of printstat64
* linux/x32/syscallent.h: Fix handlers for truncate and ftruncate.
The metag ABI has stacks growing upwards so clone expects the stack
argument to point at the bottom of the stack instead of the top.
* test/threaded_execve.c [__metag__]: Define clone2 differently
to avoid a segfault at runtime.

* test/skodic.c (main): Don't use MAP_FIXED since valid virtual addresses
vary between architectures (as far as I can tell the use of MAP_FIXED is
not relevant to the test). Also don't assume the file desriptor returned
by open call is 3 when passing it to mmap.

This is a 64bit arch w/no personalities, so fix printing.
It can now trace a simple call like readahead:
$ cat test.c
main(){readahead(-1, (unsigned long long)1 << 50, 0);}
$ gcc test.c
$ ./strace -ereadahead ./a.out
readahead(-1, 1125899906842624, 0) = -1 EBADF (Bad file descriptor)
* util.c (printllval): Handle S390X define.

Building with automake-1.13 throws an error:
configure.ac:6: error: 'AM_CONFIG_HEADER': this macro is obsolete.
You should use the 'AC_CONFIG_HEADERS' macro instead.

This makes output formatting more consistent with pread()/pwrite(),
which print their offset parameters in decimal.

The file linux/ioctlent.h is generated in the build directory, so
"../ioctlent.h" won't find it.
* linux/aarch64/ioctlent1.h: Remove "../" from include file name.

* linux/tile/ioctlent1.h: Likewise.

strace already has a mechanism to use fopen64 for output when the 64-bit
version of fopen is available on 32-bit architectures. Apply this
mechanism for other three functions to make strace fully adopted for
64-bit types.
* strace.c (struct_stat, stat_file, struct_dirent, read_dir,
struct_rlimit, set_rlimit): New macros.
(startup_attach): Use read_dir.
(startup_child): Use struct_stat and stat_file.
(main): Use struct_rlimit and set_rlimit.
struct dirent from libc should not be used for umove'ing into because it
contains fixed size d_name.
* file.c (printdir): Rename to print_old_dirent.
[SH64]: Decode using struct kernel_dirent.
[!SH64]: Decode using an open-coded struct with 32-bit d_ino and d_off.
(sys_readdir): Update.
sendfile parser used to decode off_t* parameter as a pointer to host
off_t type. With this change, it is decoded as a pointer to target long
type.
* io.c (print_off_t): New function.
(sys_sendfile): Use it.
* linux/aarch64/syscallent1.h: Use sys_sendfile64 for sendfile decoding.
* linux/tile/syscallent.h: Likewise.
* linux/x32/syscallent.h: Likewise.
* linux/x86_64/syscallent.h: Likewise.
* linux/hppa/syscallent.h: Use sys_sendfile64 for sendfile64 decoding.
* linux/metag/syscallent.h: Correct sendfile syscall name.
* linux/or1k/syscallent.h: Likewise.
* configure.ac: When libaio.h is available, check for
struct iocb.u.c.flags, IO_CMD_PWRITE and IO_CMD_PWRITEV.
* desc.c (print_common_flags): Check for HAVE_STRUCT_IOCB_U_C_FLAGS.
(sys_io_submit): Check for HAVE_DECL_IO_CMD_PWRITE and
HAVE_DECL_IO_CMD_PWRITEV.
Busybox version of timeout doesn't have --version option.
Relax check_prog to handle those cases.
* tests/init.sh (check_prog): Use type builtin to check program
availability.
