Comment:

 Ready for review.

 This will need a ChangeLog entry, viz:
 {{{
 599.?   [func]          pselkirk
         libdns++: the OPT, RRSIG, and DHCID Rdata classes now use the
         generic lexer in constructors from text.  This means that the name
         fields in such RRs in a zone file can now be non-absolute (the
         origin name in that context will be used), e.g., when loaded by
         b10-loadzone.
 }}}
