Firmware 2.2 / App 2.2.0

[Lew]

Firmware changes:

- removed 16K database object size limit so that users can create very large custom filter lists.
- fixed returning static default gateway to the app.
- CLI: added country code to "stats pkteng connections".
- changing DDNS settings now properly makes the changes immediately.
- Protect against WAN using an IPv4 link-local address.
- Port-forwarding to additional WAN IP addresses is now supported and Island will answer ARP and NDP solicitations.
- DHCP server now offers only mandatory and requested options (improves operation with Josh.ai)
- Improved SmartSwap: DHCP server now offers the previously-detected IP address, even if the client doesn't request a specific address.
- CLI: added "ip dhcp-lease" to override default lease time.
- CLI: deprecated "ip outside" as this is no longer a configurable option.
- CLI: "show history" adds the ability to filter on country code.
- If a port-forward is added for a device that doesn't support IPv6, then the IPv6 address (AAAA record) will be suppressed from DDNS automatically.
- CLI: added "ip ddns ipv6 off" to force de-publication of the IPv6 address in DDNS.
- CLI: added "ip ipv6 off" to disable IPv6 support globally.
- Cross-VPN support now works properly.
- CLI: "mac output-format" now works properly.
- the nightly miscellaneous update now writes its own log file (update-misc.log) and doesn't append to it.
- SmartSwap has much stricter rules: the existing router is acquired only if there is a single port active within the first five minutes of operation and it's an RFC 1918 address.  The existing router's identity is assumed only if more than one port is active, the port is facing a LAN, and some other port is connected to the Internet.
- IPv6 support is now properly enabled for a static IPv6 Internet connection.
