Check if it is a mapping before accessing it as such.

Web browsers and others have distrusted SHA1 a long while ago, MD2 and

@[SSL.Context] in case any use case simply needs to support older
signature algorithms.

"Resolves" an issue with incorrect dumping of this module.

We relatively recently stopped claiming that a connection was
peer_closed when in fact we gave up on the SSL connection with a fatal
alert. This caused us to signal some errors via the write callback

local_fatal state in some places we only checked for peer_closed before.

In practice this ought to have little effect though, as to accept a
ticket we also need to be in STATE_wait_for_ticket anyway.

Not negotiating the close at the TLS level is in spec, and should not
lead to sessions being purged.

* in CN / SubjectAlternativeName:dNS is supposed to only match one level
