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.

Both getaddrinfo() and getnameinfo() have to be preceeded with a call

Also, make sure to give gai_strerror() the actual error code.

we can allow it to signal an empty key for convenience.

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,
and give up without trying the other.

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.
