 * From RFC 1831:
 *
 * "A record is composed of one or more record fragments.  A record
 *  fragment is a four-byte header followed by 0 to (2**31) - 1 bytes of
 *  fragment data.  The bytes encode an unsigned binary number; as with
 *  XDR integers, the byte order is from highest to lowest.  The number
 *  encodes two values -- a boolean which indicates whether the fragment
 *  is the last fragment of the record (bit value 1 implies the fragment
 *  is the last fragment) and a 31-bit unsigned binary value which is the
 *  length in bytes of the fragment's data.  The boolean value is the
 *  highest-order bit of the header; the length is the 31 low-order bits.
 *  (Note that this record specification is NOT in XDR standard form!)"
 *
 * The Linux RPC client always sends its requests in a single record
 * fragment, limiting the maximum payload size for stream transports to
 * 2GB.

 * Universal addresses are introduced in RFC 1833 and further spelled
 * out in RFC 3530.  RPCBIND_MAXUADDRLEN defines a maximum byte length
 * of a universal address for use in allocating buffers and character
 * arrays.
 *
 * Quoting RFC 3530, section 2.2:
 *
 * For TCP over IPv4 and for UDP over IPv4, the format of r_addr is the
 * US-ASCII string:
 *
 *	h1.h2.h3.h4.p1.p2
 *
 * The prefix, "h1.h2.h3.h4", is the standard textual form for
 * representing an IPv4 address, which is always four octets long.
 * Assuming big-endian ordering, h1, h2, h3, and h4, are respectively,
 * the first through fourth octets each converted to ASCII-decimal.
 * Assuming big-endian ordering, p1 and p2 are, respectively, the first
 * and second octets each converted to ASCII-decimal.  For example, if a
 * host, in big-endian order, has an address of 0x0A010307 and there is
 * a service listening on, in big endian order, port 0x020F (decimal
 * 527), then the complete universal address is "10.1.3.7.2.15".
 *
 * ...
 *
 * For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the
 * US-ASCII string:
 *
 *	x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
 *
 * The suffix "p1.p2" is the service port, and is computed the same way
 * as with universal addresses for TCP and UDP over IPv4.  The prefix,
 * "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for
 * representing an IPv6 address as defined in Section 2.2 of [RFC2373].
 * Additionally, the two alternative forms specified in Section 2.2 of
 * [RFC2373] are also acceptable.
