These methods allow a server to switch the context when looking at ALPN and servername together. This is for example require when implementing the ACME tls-alpn/1 protocol. Unfortunately, OpenSSL does not provide any utility function to actually parse ClientHello extensions when using these APIs and the user has to write their own methods.

Coverage test seem to fail since the newly added methods are not tested without having the newer cyrptography version with the added functions too. |

Hmm, we should probably adapt the coverage bits to merge from multiple jobs (as we do on cryptography). @mhils do you have an opinion on this API? |

This PR depends on pyca/cryptography#13634 but I am not sure how to express that properly in the build files.
