Code health: simplified the conversions from IPv4 mapped
IPv6 addresses (::ffff:d.d.d.d) to their IPv4 form (d.d.d.d),
for both the binary form and human-readable form. Added
unit tests to show that the conversions work as expected.

Code health: overhauled the haproxy adapter to simplify
code and to avoid unnecessary conversions between binary
and human-readable forms. Added more unit tests for the v1
and v2 proxy protocols. A separate update will overhaul
the smtpd 'peer' lookups. Files: global/haproxy_srvr.c,

/* int normalize_v4mapped_sockaddr(
/* struct sockaddr *sa,

/*
/* int normalize_v4mapped_hostaddr(

/* DESCRIPTION
/* The functions in this module convert IPV6 addresses containing a
/* mapped IPv4 address to the IPv4 form, but only if IPv4 support
/* is enabled.
/*
/* normalize_v4mapped_sockaddr converts a V4mapped IPv6 sockaddr
/* structure (struct sockaddr_in6) to the IPv4 form (struct
/* sockaddr_in) and reduces *sa_len to (sizeof(struct sockaddr_in)).
/*
/* normalize_v4mapped_hostaddr converts a V4mapped IPv6 printable
/* address (:ffff:d.d.d.d) to the IPv4 form (d.d.d.d).
/*
/* Both functions return 0 (false) when no input was converted,
/* and return 1 (true) when input was converted.
/* BUGS
/* normalize_v4mapped_hostaddr() converts only canonical address
/* forms, not all equivalent forms.
