These classes all need to inherit from each other or the include
methods we use don't work properly.  Recreate the inheritance
structure and use overrides to change the resolv.conf parameters.

Also fix a few coding style issues.

In addition to adding the anycast DNS servers the individual
resolv.conf files are replaced with a single template.  The existing
class interfaces are preserved and they all create the appropriate
resolv.conf file by invoking the define that handles the small number
of resolv.conf variants.

Fix support for analyze_logs, which wasn't working due to the
immutable variable problems with how Puppet uses ERB.  Restructure
the template to not precalculate the results, group lines for a
particular log together, and format everything a bit better.

Also remove the old one for right now until the mistake is purged
everywhere.

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.

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.

Remove out-of-date::server.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 is the (old) master branch along with the fixes to the
cron file permissions that Russ made.
