Chrony with real-time support

[John Hasler <jhasler@debian.org>]

I have uploaded chrony_1.23-6rt1 to Experimental.  In addition to the
real-time scheduler support in chrony_1.23-6rt this version adds support
for mlockall() so that chronyd can be locked into RAM.  The features are
documented in the chronyd man page as well as in the comments in
/etc/chrony/chrony.conf.  These features will be of interest to you if you
need stable time synchronization on heavily-loaded machines: with them
chronyd will run as a real-time process and never get paged out.  There
should be no impact on peformance as chronyd is actually a small program
with modest resource requirements but running it as a real-time locked-in
process should substantially reduce latency.  Please test.
