Address some -Wold-style-declaration warnings

gcc's -Wextra pulls in -Wold-style-declaration, which triggers when a
declaration has a storage-class specifier as a non-initial qualifier.
The ISO C formal grammar requires the storage-class to be the first
component of the declaration, if present.

Seeint as the register storage-class specifier does not really have any effect

Fix problem with SCTP close_notify alerts

In SCTP the code was only allowing a send of a close_notify alert if the
socket is dry. If the socket isn't dry then it was attempting to save away
the close_notify alert to resend later when it is dry and then it returned
success. However because the application then thinks that the close_notify
alert has been successfully sent it never re-enters the DTLS code to
actually resend the alert. A much simpler solution is to just fail with a
retryable error in the event that the socket isn't dry. That way the
application knows to retry sending the close_notify alert.

Don't attempt to send fragments > max_send_fragment in DTLS

We were allocating the write buffer based on the size of max_send_fragment,
but ignoring it when writing data. We should fragment handshake messages
if they exceed max_send_fragment and reject application data writes that
are too large.

Remove special case code for SCTP reneg handling

There was code existing which attempted to handle the case where application
data is received after a reneg handshake has started in SCTP. In normal DTLS
we just fail the connection if this occurs, so there doesn't seem any reason
to try and work around it for SCTP. In practice it didn't work properly
anyway and is probably a bad idea to start with.

Add a BIO_lookup_ex() function

The existing BIO_lookup() wraps a call to getaddrinfo and provides an
abstracted capability to lookup addresses based on socket type and family.
However it provides no ability to lookup based on protocol. Normally,
when dealing with TCP/UDP this is not required. However getaddrinfo (at
least on linux) never returns SCTP addresses unless you specifically ask
for them in the protocol field. Therefore BIO_lookup_ex() is added which
provides the protocol field.

Don't fail the connection in SSLv3 if server selects ECDHE

ECDHE is not properly defined for SSLv3. Commit fe55c4a2 prevented ECDHE
from being selected in that protocol. However, historically, servers do
still select ECDHE anyway so that commit causes interoperability problems.
Clients that previously worked when talking to an SSLv3 server could now
fail.

This commit introduces an exception which enables a client to continue in
SSLv3 if the server selected ECDHE.
