print_timespec.h: conditionalize printers

This allows to implement a parser of SO_TIMESTAMP_NEW control message
without implementing extra unused printers.

* print_timespec.h (PRINT_TIMESPEC_DATA_SIZE,
PRINT_TIMESPEC_ARRAY_DATA_SIZE, PRINT_TIMESPEC, SPRINT_TIMESPEC,
PRINT_TIMESPEC_UTIME_PAIR, PRINT_ITIMERSPEC): Conditionalize.

xlat: add SO_TIMESTAMP*_NEW constants

* xlat/sock_options.in (SO_TIMESTAMP_NEW, SO_TIMESTAMPNS_NEW,
SO_TIMESTAMPING_NEW): New constants introduced by Linux commits
v5.1-rc1~178^2~363^2~4 and v5.1-rc1~178^2~363^2~3.
* xlat/scmvals.in: Likewise.

Use kernel_timeval64_t in definition of kernel_timex64_t

* kernel_timex.h: Include "kernel_timeval.h".
(kernel_timex64_t): Change the type of "time" field from a locally
defined structure to its equivalent kernel_timeval64_t.

Introduce kernel_timeval64_t type

This type is going to be used to implement parsers of SO_TIMESTAMP*_NEW
control messages.

* kernel_timeval.h: New file.
* Makefile.am (strace_SOURCES): Add it.

xlat: add _OLD suffixes to SO_RCVTIMEO and SO_SNDTIMEO

Follow the Linux kernel commit v5.1-rc1~178^2~363^2~1 and rename
these constants.

* xlat/sock_options.in (SO_RCVTIMEO): Rename to SO_RCVTIMEO_OLD.
(SO_SNDTIMEO): Rename to SO_SNDTIMEO_OLD.

Rename SO_TIMESTAMP* to SO_TIMESTAMP*_OLD

Follow the Linux kernel commit v5.1-rc1~178^2~363^2~8 and rename
these constants everywhere.

* xlat/scmvals.in (SO_TIMESTAMP): Rename to SO_TIMESTAMP_OLD.
(SO_TIMESTAMPNS): Rename to SO_TIMESTAMPNS_OLD.
(SO_TIMESTAMPING): Rename to SO_TIMESTAMPING_OLD.

to SO_TIMESTAMP_OLD.
(test_scm_timestampns): Rename SO_TIMESTAMPNS to SO_TIMESTAMPNS_OLD.
(test_scm_timestamping): Rename SO_TIMESTAMPING to SO_TIMESTAMPING_OLD.
* tests/sockopt-timestamp.c (main): Rename SO_TIMESTAMP and
SO_TIMESTAMPNS to SO_TIMESTAMP_OLD and SO_TIMESTAMPNS_OLD, respectively.

Replace SCM_TIMESTAMP* constants with SO_TIMESTAMP*

Besides the fact that SO_TIMESTAMP* constants appear to be more
standardized than SCM_TIMESTAMP*, new SO_TIMESTAMP*_OLD and
SO_TIMESTAMP*_NEW constants introduced in Linux 5.1 have no
SCM_TIMESTAMP*_OLD and SCM_TIMESTAMP*_NEW analogues.

* xlat/scmvals.in: Replace SCM_WIFI_STATUS, SCM_TXTIME, SCM_TIMESTAMP,
SCM_TIMESTAMPNS, and SCM_TIMESTAMPING with SO_WIFI_STATUS, SO_TXTIME,
SO_TIMESTAMP, SO_TIMESTAMPNS, and SO_TIMESTAMPING, respectively.
* msghdr.c: Include "xlat/sock_options.h" in XLAT_MACROS_ONLY mode.
(cmsg_socket_printers): Replace SCM_TIMESTAMP, SCM_TIMESTAMPNS, and
SCM_TIMESTAMPING with SO_TIMESTAMP, SO_TIMESTAMPNS, and SO_TIMESTAMPING,
respectively.
* tests/msg_control.c: Include "xlat/sock_options.h" in XLAT_MACROS_ONLY
mode.
(test_scm_timestamp): Replace SCM_TIMESTAMP with SO_TIMESTAMP.
(test_scm_timestampns): Replace SCM_TIMESTAMPNS with SO_TIMESTAMPNS.
(test_scm_timestamping): Replace SCM_TIMESTAMPING with SO_TIMESTAMPING.
* tests/sockopt-timestamp.c (main): Replace SCM_TIMESTAMP and
SCM_TIMESTAMPNS with SO_TIMESTAMP and SO_TIMESTAMPNS, respectively.

tests: add another test of SO_TIMESTAMP and SO_TIMESTAMPNS decoding

Unlike msg_control test, this new test makes the kernel generate
SO_TIMESTAMP and SO_TIMESTAMPNS messages.

* tests/sockopt-timestamp.c: New file.
* tests/gen_tests.in (sockopt-timestamp): New entry.
* tests/pure_executables.list: Add sockopt-timestamp.

riscv: Fixup wrong clone's arguments define

In linux kernel riscv select CLONE_BACKWARDS in
linux/arch/riscv/Kconfig, and in linux/kernel/fork.c:

SYSCALL_DEFINE5(clone, unsigned long, clone_flags, unsigned long, newsp,
