f3a16383b9 main: dump history by default 
Always write the measurement history on exit when the dump directory is
specified and silently ignore the dumponexit directive. There doesn't
seem to be a good use case for dumpdir and -r without dumponexit as the
history would be invalidated by adjustments of the clock that happened
between the dump command and chronyd exit.

f282856c72 logging: remove facility parameter 
It was never used for anything and messages in debug output already
include filenames, which can be easily grepped if there is a need
to see log messages only from a particular file.

6db8ec1ba2 privops: separate res_init() call 
Move the res_init() call from do_name_to_ipaddress() into a separate
privops operation. Use it in ntp_sources and avoid unnecessary
res_init() calls in the main thread.

7b7eb0a6e5 examples: improve systemd unit files 
Add the PrivateTmp, ProtectHome, and ProtectSystem directives to better
secure the system from chronyd. It's taken from the Debian chrony
package.

510b22e96b util: fix more coverity warnings 
Coverity doesn't seem to like the new field in the IPAddr struct (used
as explicit padding of the structure) to be left uninitialized, even
though it's never used for anything and is cleared by memset() in
UTI_IPHostToNetwork() before leaving the process.

0a0aff14d8 conf: add rawmeasurements log option 
While the measurements log can be useful for debugging problems in NTP
configuration (e.g. authentication failures with symmetric keys), it
seems most users are interested only in valid measurements (e.g. for
producing graphs) and don't expect/handle entries where some of the RFC
5905 tests 1-7 failed. Modify the measurements log option to log only
valid measurements, and for debugging purposes add a new rawmeasurements
option.

da2d33e9a8 ntp: fix time smoothing in interleaved mode 
When the server's transmit timestamp was updated with a kernel/HW
timestamp, it didn't include the time smoothing offset. If the offset
was larger than one second, the update failed and clients using the
interleaved mode received less accurate timestamps. If the update
succeeded, the clients received timestamps that were not adjusted for
the time smoothing offset, which added an error of up to 0.5s/1s to
their measured offset/delay.

Fix the update to include the smoothing offset in the new timestamp.
