properly.  Run named with 'named -r' to test.

Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const.  Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.

Minor other ISC style cleanups.

	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.

line 383: remark(1498): no prototype for the call to setup
line 405: remark(1498): no prototype for the call to cleanup
The missing prototypes were added.

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.
    */

files as root

if there was exactly one non-option argument (as in 'named foo')
it was silently ignored - issue a usage message instead;
also issue a usage message if we get an unknown command line option;
update the update message to reflect reality (leaving the -x option
undocumented)

end first line of two-line error messages with a colon

in case isc_log_* is what is causing the assertion/error.

Check bounds on port of -p option.

Start OMAPI on startup, destroy it on shutdown.

log to syslog if deamon.
implement `-t' option and chroot

the server object are always fatal, and errors that occur when
reconfiguring an existing server are always nonfatal.
