CLOCK_REALTIME is a "wall clock" time. It's still affected by NTP
changes (for Linux we should probably use CLOCK_TAI instead

This first gets the clock_gettime_mono() value, converts to an NTTIME (as
this is what is stored in the dos attribute EA), then mixes in 8 bits of
randomness shifted up by 55 bits to cope with poor resolution clocks to
avoid duplicate inodes.
Using 8 bits of randomness on top of an NTTIME gives us around 114
years headroom. We can now guarentee returning a itime-based

Before the CVE-2020-25717 fixes we had a fallback from
getpwnam('DOMAIN\user') to getpwnam('user') which was very dangerous and
unpredictable.
Now we do the fallback based on sid_to_uid() followed by
getpwuid() on the returned uid.
This obsoletes 'username map [script]' based workaround adviced
for CVE-2020-25717, when nss_winbindd is not used or
idmap_nss is actually used.
In future we may decide to prefer or only do the SID/UID based
lookup, but for now we want to keep this unchanged as much as possible.
