   …-key, r=arlosi
   
   Added new GitHub RSA Host Key
   
   GitHub rotated their RSA host key which means that cargo needs to update it.  Thankfully the other keys were not rotated so the impact depends on how cargo connected to github.

2. Auto merge of rust-lang#11889 - est31:revoke_old_github, r=ehuss …

   Add the old github keys as revoked
   
   The patch to update the bundled ssh github host key did not change anything for users who already had connected to github one time before via ssh: if the attacker had access to the old key, they'd be vulnerable to MITM attacks as their known_hosts file would list the old github key. Only if they connected again to github without attacker access, or if they saw the announcement of the key rotation, they would update their key.
   
   There is sadly no other way to distribute revocations of old host keys to clients other than to bundle them with client software.
