The deprecated classes base::newsyslog::messages::sa and
base::newsyslog::messages::sa::override have been deleted.  Global
overrides for the default base::newsyslog behavior should be put into
the local defaults module instead.

The ::override subclass was also using the class variable.

A refactoring of base::newsyslog removed a variable that it was
assuming was set.

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.

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.

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