Do not send routers (option 3) or static routes (option 33) when
classless static routes (option 121, 249) are sent. RFC 3442 says
servers SHOULD NOT send those options.

This avoids confusing clients who fail to ignore the routers or
static routes options in the presence of classless static routes
options. RFC 3442 says clients MUST ignore those options.

Incorrect behavior in MS and Linux clients reported by Juan on
misc@.

More tweaking of option processing, this time around the creation of
the priority list. Add create_priority_list() and use it to
consistantly merge mandatory, supplied and default option priority
lists into a reliable and complete list of options sorted by priority.
No intended functional change other than ensuring all options
available are returned.
