chrony calls getrandom() at startup if available, so it needs a workaround
for the blocking behaviour on recent (4.14.39+), similar to what was done
for util-linux in commit c4d86707cd (util-linux: add two upstream patches
to fix blocking on getrandom() with recent kernels).

With CHRONY_ARGS in /etc/default/chrony, chrony may asked to use an
alternative configuration file (with the -f option), so drop the explicit
/etc/chrony.conf check.
In case the configuration file isn't present chrony will anyway loudly
complain which is preferable to this silent failure:
chronyd -f /non/existing/file.conf
Could not open configuration file /non/existing/file.conf : No such file or directory

Chrony has the ability to support PPS. Its enablement is determined
primarily from the existence of `sys/timepps.h`. This file is provided
from the pps-tools package. Adjusting Chrony's Makefile to depend on the
pps-tools package if a developer has included pps-tools as part of a
build. Relates to 2cfc966f43.

With the new version, documentation is not generated part of the main
build. This removes the need to alter the Makefile to remove the invoke

libtomcrypt at this time).

Fixes CVE-2014-0021: Amplification in chrony control protocol
In the chrony control protocol some replies are significantly larger than
their requests, which allows an attacker to use it in an amplification
attack. With hosts allowed by cmdallow (only localhost by default) the
maximum amplification factor is 9.2. Hosts that are not allowed receive a
small reply with error status, which allows amplification of up to 1.5.
To fix the problem, the protocol has been modified to require padding in the
request packet, so replies are never larger than their requests. Also,
chronyd no longer sends replies with error status to hosts that are not
allowed by cmdallow.
