As those are pretty unusual, let's add some additional information
that can be reported by users.
* util.c (print_quoted_string_ex, dumpstr): Add reasons for memory
allocation errors.
(sizeof_iov): Change type from size_t to unsigned int.
(dumpiov_upto): Rewrite size initialisation similarly to the way it's
done in print_quoted_string_ex, add reasons for memory allocation errors.

The current way of designation of 64-bit specific syscalls in x32
personality not only conflicts with fault injection specification
syntax, but also makes it impossible to specify such syscalls at all
(since everything that starts from a digit is considered a syscall
number specification). So, let's change prefix to suffix and use
octothorpe instead of colon as a separator.
* linux/x32/syscallent.h (13, 15, 16, 19, 20, 45, 46, 47, 54, 55, 59,
101, 127, 128. 129, 131, 134, 156, 174, 177, 178, 180, 205, 206, 209,
211, 214, 215, 222, 236, 244, 246, 247, 273, 274, 278, 279, 295, 296,
297, 299, 307, 310, 311, 32, 327, 328): Change "64:" prefix to "#64"
suffix in syscall name.
Closes: https://github.com/strace/strace/issues/36

If Thumb code is being generated and frame pointers are enabled, the
Thumb frame pointer in r7 clashes with any local variable which may
need to be assigned to r7 (e.g. the syscall NR when making a raw
syscall).
With gcc, the double use of r7 results in a build error, e.g.
strace-4.22/tests/inject-nf.c:86:1: error: r7 cannot be used in asm here
With clang, the double use of r7 can result in the compiler silently
generating broken code which crashes at run time due to frame pointer
corruption:
https://bugs.llvm.org/show_bug.cgi?id=34165
In most cases the problem isn't visible as frame pointers will be
disabled automatically due to optimisation level. However to handle
cases where frame pointers are enabled (e.g. when CFLAGS etc are set
to support a debug build, etc) provide a version of raw_syscall_0
which manually saves and restores the frame pointer value in r7
to a temporary register before setting up the syscall NR in r7
and invoking the syscall.
* linux/arm/raw_syscall.h (raw_syscall_0) [__thumb__]: Provide
an alternative version.

Sync them with kernel's include/linux/socket.h, since syscalls perform
almost no checks for incorrect flags.
* xlat/msg_flags.in (MSG_OOB, MSG_PEEK, MSG_DONTROUTE, MSG_CTRUNC,
MSG_PROBE, MSG_TRUNC, MSG_DONTWAIT, MSG_EOR, MSG_WAITALL, MSG_FIN,
MSG_SYN, MSG_CONFIRM, MSG_RST, MSG_ERRQUEUE, MSG_NOSIGNAL, MSG_MORE,
MSG_WAITFORONE, MSG_FASTOPEN, MSG_CMSG_CLOEXEC): Add default values
to all constants.
(MSG_SENDPAGE_NOTLAST, MSG_NO_SHARED_FRAGS): New constants. It is
an internal one, but, apparently, nothing prohibits passing it
to the kernel.
(MSG_CMSG_COMPAT): New constant. Override the value provided
by system headers.
(MSG_EOF): Commented out, as it is a synonym for MSG_FIN.

* socketutils.c (unix_send_query): Do not add NLM_F_DUMP to nlmsg_flags
when kernel version is 4.4.4 or later, initialize udiag_cookie
unconditionally.
Complements: v4.12~536 ("Change unix_diag requests back to use full dump instead of exact match")
This information is not used and it looks like it negatively affects
ability to find the socket under high load.

flag from netlink_diag_req.ndiag_show field.
* tests/netlink_netlink_diag.c (send_query) <req>: Likewise.

SO_ATTACH_FILTER and SO_GET_FILTER have the same value; the former
constant is intended for use in setsockopt, and the latter is for
getsockopt. Handle that the same way as similar SOL_IP/SOL_IPV6 socket
options are handled.
* xlat/getsock_options.in: New file.
* xlat/setsock_options.in: Likewise.
* xlat/sockoptions.in (SO_ATTACH_FILTER): Move to
xlat/setsock_options.in.

(print_sockopt_fd_level_name) <case SOL_SOCKET>: Use
getsock_options or setsock_options as auxiliary xlats based on the value
of is_getsockopt flag.
* tests/sock_filter-v.c: Update expected output.

There is no need to provide duplicate fallback definitions anymore,
inclusion of the appropriate xlat header in XLAT_MACROS_ONLY mode
does the right thing.

Remove, a fallback definition is already provided by included

Sometimes we need just fallback definitions and nothing else.
This change adds an interface of skipping xlat table prototypes
and definitions.
* xlat/gen.sh (gen_header): Place xlat table prototype or definition
under "#ifndef XLAT_MACROS_ONLY" guard.

As the header with command definitions is now a part of UAPI (since
Linux commit v4.16-rc1~21^2~11), there's no need for a very special
printing routine for command names.
* s390.c (SYS_FUNC(s390_runtime_instr)): Use printxval_d to print
the command argument.
* tests/s390_runtime_instr.c: Update expected output.
