                        512 byte receive buffer if the initial EDNS queries
                        fail.  [RT #14852]

1952.   [func]          The maximum EDNS UDP response named will send can
                        now be set in named.conf (max-udp-size).  This is
                        independent of the advertised receive buffer
                        (edns-udp-size). [RT #14852]

                        max-clients-per-query.

                        a query.

                        be secure (dnssec-must-be-secure).

                        child zones for which we don't have a supported
                        algorithm.  Such child zones are treated as unsigned.

                        the total number of of recursive lookups being
                        processed exceeds max-recursive-clients, even
                        if some of the lookups are internally generated.

own CVS tree will help minimize CVS conflicts.  Maybe not.
Blame Graff for getting me to trim all trailing whitespace.

	dns_dispatch_create() no longer exists.  dns_dispatch_createtcp()
	and dns_dispatch_getudp() are the replacements.  _createtcp() takes
	a bound, connected TCP socket, while _getudp() will search for
	a sharable UDP socket, and if found, attach to it and return a
	pointer to it.  If one is not found, it will create a udp socket,
	bind it to a supplied local address, and create a new dispatcher
	around it.

	dns_dispatch_remove{request,response}() no longer take the dispatch
	as an argument.

	query-source can now be set per view.

	The dispatch manager holds onto three memory pools, one for
	allocating dispatchers from, one for events, and one for
	requests/replies.  The free list on these pools is hard-coded,
	but set to 1024.  This keeps us from having to dig into the
	isc_mem_t the pools draw from as often.

	dns_resolver_create() and dns_view_createresolver() require that
	valid dispatchers be passed in; dispatchers are no longer created
	for the caller.

Cleanup of redundant/useless header file inclusion.

ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
   /*
    * This is a comment.
    */

headers and adding it to source files that need it.
