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.

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.

Because of the way bio_lcl.h is organised, we must not include

Because different platforms have different levels of support for IPv6,
different kinds of sockaddr variants, and some have getaddrinfo et al
while others don't, we could end up with a mess if ifdefs, duplicate
code and other maintainance nightmares.

Instead, we're introducing wrappers around the common form for socket
communication:
BIO_ADDR, closely related to struct sockaddr and some of its variants.
BIO_ADDRINFO, closely related to struct addrinfo.

With that comes support routines, both convenient creators and
accessors, plus a few utility functions:

BIO_parse_hostserv, takes a string of the form host:service and
splits it into host and service.  It checks for * in both parts, and
converts any [ipv6-address] syntax to ust the IPv6 address.

BIO_lookup, looks up information on a host.

All routines handle IPv4 (AF_INET) and IPv6 (AF_INET6) addresses, and
there is support for local sockets (AF_UNIX) as well.

CRIME protection: disable compression by default, even if OpenSSL is
compiled with zlib enabled. Applications can still enable compression by
calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by using
the SSL_CONF library to configure compression. SSL_CONF continues to
work as before:

SSL_CONF_cmd(ctx, "Options", "Compression") enables compression.

SSL_CONF_cmd(ctx, "Options", "-Compression") disables compression (now
no-op by default).

The command-line switch has changed from -no_comp to -comp.
