Subject: [PATCH 1/9] Fix SSL_select_next_proto
Ensure that the provided client list is non-NULL and starts with a valid
entry. When called from the ALPN callback the client list should already
have been validated by OpenSSL so this should not cause a problem. When
called from the NPN callback the client list is locally configured and
will not have already been validated. Therefore SSL_select_next_proto
should not assume that it is correctly formatted.
We implement stricter checking of the client protocol list. We also do the
same for the server list while we are about it.

Subject: [PATCH 2/9] More correctly handle a selected_len of 0 when processing
NPN
In the case where the NPN callback returns with SSL_TLEXT_ERR_OK, but
the selected_len is 0 we should fail. Previously this would fail with an
internal_error alert because calling OPENSSL_malloc(selected_len) will
return NULL when selected_len is 0. We make this error detection more
explicit and return a handshake failure alert.

Subject: [PATCH 9/9] Add a test for an empty NextProto message
It is valid according to the spec for a NextProto message to have no
protocols listed in it. The OpenSSL implementation however does not allow
us to create such a message. In order to check that we work as expected
when communicating with a client that does generate such messages we have
to use a TLSProxy test.
