With this change, PowerDNS core gains ability to encrypt & decrypt IP addresses as described in https://medium.com/@bert.hubert/on-ip-address-encryption-security-analysis-with-respect-for-privacy-dabe1201b476 For IPv4 this uses ipcrypt, for IPv6 it uses a 128-bit AES ECB operation. This CR also hooks up ipencrypt() and ipdecrypt() methods for dnsdist use, specifically to pseudonomyse logging.

This would cause dnsdist to be linked against libgnutls and $(LIBSSL_LIBS) when they are available, regardless of whether DNS over TLS support is enabled. If I'm not mistaken you only need to link against $(LIBCRYPTO_LIBS) for this to work?

yes, that is correct, but I did not find a way to make that happen correctly.

Short description
With this change, PowerDNS core gains ability to encrypt & decrypt IP addresses as described in https://medium.com/@bert.hubert/on-ip-address-encryption-security-analysis-with-respect-for-privacy-dabe1201b476
For IPv4 this uses ipcrypt, for IPv6 it uses a 128-bit AES ECB operation.
This PR also hooks up ipencrypt() and ipdecrypt() methods for dnsdist use, specifically to pseudonomyse logging.
