* Feat add basic support for IPv6 networks
Newly generated networks automatically generate an IPv6 prefix of size
64 within the ULA address range, devices obtain a randomly generated
address within this prefix.
Currently, this is Linux only and does not yet support all features
(routes currently cause an error).
* Fix firewall configuration for IPv6 networks
* Fix routing configuration for IPv6 networks
* Feat provide info on IPv6 support for specific client to mgmt server
* Feat allow configuration of IPv6 support through API, improve stability
* Feat add IPv6 support to new firewall implementation
* Fix peer list item response not containing IPv6 address
* Fix nftables breaking on IPv6 address change
* Fix build issues for non-linux systems
* Fix intermittent disconnections when IPv6 is enabled
* Fix test issues and make some minor revisions
* Fix some more testing issues
* Fix more CI issues due to IPv6
* Fix more testing issues
* Add inheritance of IPv6 enablement status from groups
* Fix IPv6 events not having associated messages

* Improve code for IPv6 DNS server selection, add AAAA custom records
* Ensure IPv6 routes can only exist for IPv6 routing peers
* Fix IPv6 network generation randomness
* Fix a bunch of compilation issues and test failures
* Replace method calls that are unavailable in Go 1.21
* Fix nil dereference in cleanUpDefaultForwardRules6

* Add a bunch of client-side test cases for IPv6
* Fix IPv6 tests running on unsupported environments
* Fix import cycle in tests
* Add missing method SupportsIPv6() for windows
* Require IPv6 default route for IPv6 tests
* Fix panics in routemanager tests on non-linux
* Fix some more route manager tests concerning IPv6
* Add some final client-side tests

Add netstack support for the agent to run it without privileges.
- use interface for tun device
- use common IPC for userspace WireGuard integration
- move udpmux creation and sharedsock to tun layer
