This has support for log rotation (or re-opening).
The log format is updated to use an RFC5424 timestamp and to include a
hostname. The addition of the hostname allows trivial merging of log
files from multiple cluster nodes.
The hostname is faked from the CTDB_BASE environment variable during
testing, as per the comment in the code. It is currently faked in a
similar manner in local_daemons.sh when printing logs, so drop this.
Unit tests need updating because stderr logging no longer produces a
"PROGNAME[PID]: " header.

RFC5952 says the existing style is not recommended and the [] style

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
fileid in a normal share (storing dos attributes in an EA).

against a "normal" share, then read info on them

This shows that even on ext4, this is enough to
