The delegate was lost due to not being retained anywhere, and the
WireGuard adapter was therefore not finalizing the connection (i.e. set
tunnel settings).
Regression in #1057
### OpenVPN
- Make CPassepartoutCryptoOpenSSL agnostic of PassepartoutKit
- Move Allocation/ZeroingData from PassepartoutKit to package for
internal use
- Rename ZeroingData.count to .length for consistency with NSData
- Duplicate some Data manipulation code in CryptoOpenSSL
- Retain a simplified version of ZeroingData in PassepartoutKit
(AutoerasingData)
### WireGuard
- Make WireGuardKit imports `internal`
Simplify development and maintenance immensely by making this a
monorepository:
- Convert PassepartoutKit and VPN bindings to local packages
- OpenVPN/OpenSSL
- WireGuard/Go
- Make PassepartoutKit available via
- Source submodule for production (private)
- [Binary XCFramework for
development](https://github.com/passepartoutvpn/passepartoutkit)
- Add PassepartoutKit Demo in root
- Deploy package later
