 Subtask of #2368.  Depend on #2377.

 See BIND 9's lib/dns/master.c:load_text().  In particular, this part
 and code around it:

 {{{#!c
                 /*
                  * Find TTL, class and type.  Both TTL and class are
 optional
                  * and may occur in any order if they exist. TTL and class
                  * come before type which must exist.
                  *
                  * [<TTL>] [<class>] <type> <RDATA>
                  * [<class>] [<TTL>] <type> <RDATA>
                  */
 }}}

 Consider delegating to a separate method to keep each method
 manageable.
