Reverts PR2152 reported as causing OpenVPN issues here: https://forum.pfsense.org/index.php?topic=104175.0

Fix gen_subnetv4_max

and use it in services_dhcp rather than trying to do the similar
calculation in-line.
Should fix redmine #5654 and probably a bunch of other things that use
gen_subnet_max

Flush zone's tables if its db must be reset to avoid leaving behind any table entries. Ticket #5622

Add busytimeout of 60 seconds for CP database access. This matches the default value PHP uses with sqlite 2.x versions (pfSense 2.1.x and earlier) and prevents the issues noted in Ticket #5622

Nuke fifolog support. It was never used or fully implemented, no GUI option, and didn't end up working out.
It buffered writes too long, users could never see the most current log data.

Merge pull request #2263 from phil-davis/r016

Consolidate OpenVPN kill_client routine

After a gitsync just now I started getting "cannot redeclare
kill_client" error messages. Whatever it was that caused this to start

Might as well put it in openvpn.inc

No need to set LANG env var here
