Feature improvements

• Update dictionary.aruba
• Add set home_server state ... down in order to mark the home server as administratively down. Use alive to bring it back to life.
• Add Post-Auth-Type Client-Lost which should make it easier to log when clients stop responding.
• Add sites-available/totp as an example of how to use TOTP.
• Add %{mschap:Domain-Name}, fixes #3944.
• Cache TLS messages in &session-state, for more debugging.
• Notes in eap configuration about TLS 1.0 / TLS 1.1, and setting cipher_list = "DEFAULT@SECLEVEL=1"
• Added many warning messages about using TLS 1.3 with EAP. In short, don't use it. Microsoft will support it in fall 2021.

Bug fixes

• Fix crash in some cases when home server is down, in debug mode.
• Fix (again) "read clients from SQL" functionality.
• Fix sql_map to return values in more situations.
• Silently ignore LEAP configuration instead of erroring out.
