  to swanctl.conf swanctl/vici style. Issue #9603

Fix copyright message years to reflect BSDP -> ESF -> Netgate

routing, when a new pppoe connection is made the gatewaymonitor should be started before decisions about default route can be properly made. also for 'automatic' provide a fallback to the first enabled gateway thats configured, just in case..

Correct PHP syntax error that leads to a PHP 7 error.

Update the Copyright notice for pfSense.

Some systems - only one that I am aware of, complain that unbound is starting before dchp6 has completed leading to problems, this occurs only on boot.

Further examination did indeed show that the problem is caused by unbound starting before the dhcp6c - RTSOLD - rc.newwanipv6 have completed, making sure that these have all run before unbound is allowed to start corrects the problem....

Move copyright from ESF to Netgate

just exit for v6, gateways setup above.

fix booting check

Setup gateway monitors and exit in rc.newwanip(v6) if system is booting. Ticket #6186

Log if rc.newwanip(v6) is called with empty interface.

Don't exit if the system is booting, should always be unnecessary. related to Ticket #5952

Clarify log, remove old commented out things that are unnecessary.

Kicking ntpd in rc.newwanip(v6) dates back to OpenNTPD which didn't have dynamic interface scanning support. This seems to be the source of crashes in ntpd as described in Ticket #4155, and appears to be unnecessary.
