`strncpy(hnbuf, h->hdr_text, h->hdr_namelen)` assumes that hdr_namelen will never be longer than ARC_MAXHEADER, but that assumption wasn't enforced anywhere. Enforcing the maximum header name length in arc_parse_header_field() seems reasonable, and prevents malformed headers from overrunning this buffer.

From the restriction of RFC5322 section 2.1.1 and section 2.2, length of email header field name cannot be more than 997. With this commit, we define a constant macro for it, and then apply this restriction on parsing header field. Also, reduce size of a buffer for copying header field name. * libopenarc/arc.h (ARC_MAXLINELEN, ARC_MAXHDRNAMELEN): New macros. * libopenarc/arc.c (arc_parse_header_field, ar_eoh): Use ARC_MAXHDRNAMELEN as maximum length of header field names.
