Comment cleanups (ie, many "'t' are a valid." comments made grammatically
correct).

                        isc_file_getmodtime, isc_mktemplate renamed to
                        isc_file_mktemplate and isc_ufile renamed to
                        isc_file_openunique.  By no means an exhaustive API,
                        it is just what's needed for now.

of dns_rbt_findnode should be skipped.  Nothing external uses it yet, but
when the chain option is NULL, this option is set internally as predecessor
searching is irrelevant.  (It was skipped before now, but via a different
mechanism.)

Add DNS_RBTFIND_NOOPTIONS to make it clear what the options parameter of
dns_rbt_find* is when no options are passed, and use it in dns_rbt_deletename.

REQUIRE that DNS_RBTFIND_NOEXACT and DNS_RBTFIND_NOPREDECESSOR are mutually
exclusive to dns_rbt_findnode.

dns_rbt_find* is when no options are passed.

Add DNS_RBTFIND_NOPREDECESSOR to specify that the predecessor
searching code of dns_rbt_findnode should be skipped.
