newsyslog no longer sets up a weekly command to tar up
/root/.history-save and removes /etc/newsyslog.weekly/audit if it
exists.  We're no longer using per-user history files and we're
letting bash handle managing the length of the history file.

newsyslog now creates btmp and wtmp writable by group utmp, matching
the operating system defaults.

newsyslog no longer attempts to clean up sysklogd cron jobs or remove
the old /etc/newsyslog.daily/syslog file installed by ancient versions
of stanford-server.

General coding style cleanup.

Make the script executable, test analyze_logs, and fix for to_s
on an array no longer resulting in a good template string.

newsyslog::config now supports a new analyze_logs parameter, which
specifies the list of logs to run through the analyze action (when
different than the list in logs).  analyze_logs defaults to logs if
not given.

Also update the coding style, simplify the define drastically, and
clean up indentation and comments.

This was testing the old Apache newsyslog configuration template,
which no longer exists.

Remove out-of-date::server.  This is only used on a single host, so
all of the files and Puppet manifest have been moved to the Puppet
model for that server.

We've switched completely to Kerberized ssh and no longer install
Kerberos rlogin or rsh.

This was only missing because our mirror script didn't know about
it.  That's now been fixed, so add wheezy-updates back into the
default sources.list for wheezy.

Remove some comments that don't make sense in the generated file.

error: ssh_msg_send: write appears to be from a network connection
error.  It was logged on git.stanford.edu.  I don't think we care
about it.

The new version of remctld changes some of the logged error messages.
Update the filter-syslog rules accordingly.

This is the (old) master branch along with the fixes to the
cron file permissions that Russ made.
