Daniel McArdle	00e434d67e	Add ECH server (draft-ietf-tls-esni-09). This CL adds an initial implementation of the ECH server, with pieces of the client in BoGo as necessary for testing. In particular, the server supports ClientHelloInner compression with ech_outer_extensions. When ECH decryption fails, it can send retry_configs back to the client. This server passes the "ech-accept" and "ech-reject" test cases in tls-interop-runner[0] when tested against both the cloudflare-go and nss clients. For reproducibility, I started with the main branch at commit 707604c262d8bcf3e944ed1d5a675077304732ce and updated the endpoint's script to pass the server's ECHConfig and private key to the boringssl tool. Follow-up CLs will update HPKE to the latest draft and catch us up to draft-10.

Add ECH server (draft-ietf-tls-esni-09).

This CL adds an initial implementation of the ECH server, with pieces of
the client in BoGo as necessary for testing. In particular, the server
supports ClientHelloInner compression with ech_outer_extensions. When
ECH decryption fails, it can send retry_configs back to the client.

This server passes the "ech-accept" and "ech-reject" test cases in
tls-interop-runner[0] when tested against both the cloudflare-go and nss
clients. For reproducibility, I started with the main branch at commit
707604c262d8bcf3e944ed1d5a675077304732ce and updated the endpoint's
script to pass the server's ECHConfig and private key to the boringssl
tool.

Follow-up CLs will update HPKE to the latest draft and catch us up to
draft-10.
