Update manpages to mention new --log-file option.

Move vlog option descriptions into a separate file lib/vlog.man that
is substituted into manpages.

Get rid of individual rules for substituting most files in favor of
a single suffix rule.  Unfortunately this loses the (Emacs-specific)
read-only markings but it simplifies the makefiles.

-\fIlevel\fR.  The \fImodule\fR may be any valid module name (as

-for logging to the system log or to the console, respectively, or
-\fBANY\fR to set the logging levels for both facilities.  If it is

-be one of \fBemer\fR, \fBerr\fR, \fBwarn\fR, or \fBdbg\fR, designating
