Recognize '<>' as a special case of an angle-addr in header_value_parser.

Browse source 
Although '<>' is invalid according to RFC 5322, SMTP uses it for various
things, and it sometimes ends up in email headers.  This patch changes
get_angle_addr to recognize it and just register a Defect instead of raising a
parsing error.
