travis: Move fastest test configuration first

I use Travis CI to check each patch before sending my patchsets.  Most
failures are simple and make all test configurations fail.  However, since
Travis CI runs test configurations in order and given that the first three
configurations are the slowest ones, it takes about twenty minutes to see
the failure.  Moving the fastest test configuration first would allow to
fail earlier.  It would become about 3x faster to fail in case of simple
mistakes.

* .travis.yml (CC=gcc, STACKTRACE=no): Move to first position.

print_timespec.h: parametrize TIMESPEC_T.tv_nsec

This is going to be used to implement a parser of SO_TIMESTAMP_NEW
control message.

* print_timespec.h [!TIMESPEC_NSEC] (TIMESPEC_NSEC): Define to tv_sec.
(TIMESPEC_TO_SEC_NSEC, timespec_fmt, print_timespec_t_utime): Use
TIMESPEC_NSEC instead of tv_sec.

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.

(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.

SCM_TIMESTAMPING with SO_TIMESTAMP, SO_TIMESTAMPNS, and SO_TIMESTAMPING,
respectively.

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.
* tests/.gitignore: Likewise.
