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.

Add no-async option to Configure that forces ASYNC_NULL.
Related to RT1979
An embedded system or replacement C library (e.g. musl or uClibc)
may not support the *context APIs that are needed for async operation.

Compiles with musl. Ran unit tests, async tests skipped as expected.

When connecting to "localhost" the Proxy's choice of client address
family may not match the server's choice address family.  Without
MultiHomed => 1, the proxy may try the wrong address family first,

This makes use of TLSProxy, which was expanded to use IO::Socket::IP

be more popular) instead IO::Socket::INET if one of them is installed.

s_socket.c gets brutally cleaned out and now consists of only two
functions, one for client and the other for server.  They both handle
AF_INET, AF_INET6 and additionally AF_UNIX where supported.  The rest
is just easy adaptation.

Both s_client and s_server get the new flags -4 and -6 to force the
use of IPv4 or IPv6 only.

Also, the default host "localhost" in s_client is removed.  It's not
certain that this host is set up for both IPv4 and IPv6.  For example,
Debian has "ip6-localhost" as the default hostname for [::1].  The
better way is to default |host| to NULL and rely on BIO_lookup() to
return a BIO_ADDRINFO with the appropriate loopback address for IPv4
or IPv6 as indicated by the |family| parameter.
