pids to $pidfile (one pid per line).
Our check_pidfile() from rc.subr will get only first pid and use it for
stop/status/etc which is incorrect.
Do not use pidfile for that, rather use $procname to get the list of running
haproxy processes.
[If you know how to do the same with pidfile, please tell me.]
literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().
In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.
