Eugene Syromyatnikov 3277a2370a Always print raw values of time data fields
Refactor sprinttime: implement sprinttime_nsec and sprinttime_usec
that handle nanoseconds and microseconds, respectively.
Always print raw values of time data fields, format string
representations of time as comments.

* defs.h (sprinttime): Change argument type from time_t to long long.
(sprinttime_nsec, sprinttime_usec): New prototypes.
* util.c (sprinttime_ex, sprinttime_nsec, sprinttime_usec): New
functions.
(sprinttime): Turn into a thin wrapper around sprinttime_ex.
* stat.h (struct strace_stat): Add has_nsec field.
* fetch_struct_stat.c (HAVE_NSEC): New macro.
(fetch_struct_stat): Initialize has_nsec field with HAVE_NSEC.
* fetch_struct_stat64.c (HAVE_NSEC): New macro.
(fetch_struct_stat64): Initialize has_nsec field with HAVE_NSEC.
* print_struct_stat.c (print_struct_stat) <PRINT_ST_TIME>:
Print raw values of time fields, use sprinttime_nsec to format a string
representation of time, use tprints_comment to print it as a comment.
* statx.c (SYS_FUNC(statx)) <PRINT_FIELD_TIME>: Likewise.
* utime.c (SYS_FUNC(utime)): Print raw values of struct utimbuf.actime
and struct utimbuf.modtime fields, use sprinttime to format a string
representation of time, use tprints_comment to print it as a comment.
* tests/tests.h (print_time_t_nsec): Add int argument.
* tests/print_time.c (print_time_t_ex): New function.
(print_time_t_nsec): Add int argument, turn into a thin wrapper around
print_time_t_ex.
* tests/utime.c (main): Update expected output.
* tests/xstatx.c [!IS_STATX] (HAVE_NSEC): New macro.
[!IS_STATX] (PRINT_ST_TIME), [IS_STATX] (PRINT_FIELD_TIME): Update
expected output.
* NEWS: Mention this timestamps representation improvement.
