Indicate timezone offsets in timestamps
Logs and other output carrying timestamps will have now timezone offsets indicated, eg.: [2020-03-12 07:01:05.584482 +0000] I [MSGID: 106143] [glusterd-pmap.c:388:pmap_registry_remove] 0-pmap: removing brick (null) on port 49153 To this end, - gf_time_fmt() now inserts timezone offset via %z strftime(3) template. - A new utility function has been added, gf_time_fmt_tv(), that takes a struct timeval pointer (*tv) instead of a time_t value to specify the time. If tv->tv_usec is negative, gf_time_fmt_tv(... tv ...) is equivalent to gf_time_fmt(... tv->tv_sec ...) Otherwise it also inserts tv->tv_usec to the formatted string. - Building timestamps of usec precision has been converted to gf_time_fmt_tv, which is necessary because the method of appending a period and the usec value to the end of the timestamp does not work if the timestamp has zone offset, but it's also beneficial in terms of eliminating repetition. - The buffer passed to gf_time_fmt/gf_time_fmt_tv has been unified to be of GF_TIMESTR_SIZE size (256). We need slightly larger buffer space to accommodate the zone offset and it's preferable to use a buffer which is undisputedly large enough. This change does *not* do the following: - Retaining a method of timestamp creation without timezone offset. As to my understanding we don't need such backward compatibility as the code just emits timestamps to logs and other diagnostic texts, and doesn't do any later processing on them that would rely on their format. An exception to this, ie. a case where timestamp is built for internal use, is graph.c:fill_uuid(). As far as I can see, what matters in that case is the uniqueness of the produced string, not the format. - Implementing a single-token (space free) timestamp format. While some timestamp formats used to be single-token, now all of them will include a space preceding the offset indicator. Again, I did not see a use case where this could be significant in terms of representation. - Moving the codebase to a single unified timestamp format and dropping the fmt argument of gf_time_fmt/gf_time_fmt_tv. While the gf_timefmt_FT format is almost ubiquitous, there are a few cases where different formats are used. I'm not convinced there is any reason to not use gf_timefmt_FT in those cases too, but I did not want to make a decision in this regard.
