Get real interface when dhcrelay uses default GW

If the DHCP Relay server is not on any local subnet, and not on any subnet that has an internal static route, but is somewhere that no specific route is known, then this code finds the default gateway and uses that in the DHCP relay "-i" parameter. The current code gets just the interface name (like "wan", "opt1"). But DHCP Relay command needs to be fed the actual device name "vr0", "vr1" etc....

tls-verify requires quotes around the command to be executed. Ticket #3596

fixing typo for GIF tunnels to work over IPv6

the call of get_interface_gatewayv6() in the creation of a GIF tunnel over IPv6 leads to a "Fatal error: Call to undefined function get_interface_gatewayv6() in /etc/inc/interfaces.inc on line 934". changeing the function call to get_interface_gateway_v6() fixed it for me on my local system.

Correct typo on function name that has slipped unnoticed. Reported-by: https://forum.pfsense.org/index.php?topic=74688.0

Merge pull request #1055 from ExolonDX/branch_master_10

Make extra sure that we do not start multiple instances of dhcpleases if, for example, the PID is stale/invalid and there is still a running instance.

Put the fix to be more generic to prevent any other leak possible in the long run. Fixes #3062
