MR: #1870

Clang rightly does not like extern symbols that are not declared
in any header file, as typically these are not intended for global
visibility and are exposed in error.  This was indeed the case with
various file-scope objects in dtlsv1listentest.c.

Make it clear that if we are unable to get hold of the peer address then
*peer is cleared and the family set to AF_UNSPEC.

Adds a set of tests for the newly rewritten DTLSv1_listen function.
The test pokes various packets at the function and then checks
the return value and the data written out to ensure it is what we
would have expected.

The recently rewriten DTLSv1_listen code does not support fragmented
ClientHello messages because fragment reassembly requires server state
which is against the whole point of DTLSv1_listen. This change adds some
partial support for fragmented ClientHellos. It requires that the cookie
must be within the initial fragment. That way any non-initial ClientHello
fragments can be dropped and fragment reassembly is not required.

Adds a new function BIO_ADDR_clear to reset a BIO_ADDR back to an

The DTLSv1_listen function exposed details of the underlying BIO
abstraction and did not properly allow for IPv6. This commit changes the
"peer" argument to be a BIO_ADDR and makes it a first class function
(rather than a ctrl) to ensure proper type checking.

This uilds on the same way of checking for availability as we do in
TLSProxy.  We use all IP factories we know of, starting with those who
know both IPv6 and IPv4 and ending with the one that only knows IPv4
and cache their possible success as foundation for checking the
available of each IP domain.

80-test_ssl.t has bigger chances of working on platforms that do not
run both IP domains.
