4.4BSD snapshot (revision 8.1); add 1993 to copyright

various lintish things come to light by protoypes.

need to free RR packets (plug mbuf leak reported by MITRE)

changes from dkhusema

new conventions for kernel header includes (by sklower);
version of oct 11, 1992

routing tables set up after proto inits called now, need lazy evaluation.

changes to add routing tables via the domain switch

change required by using routing vector instead of linked list

use pk_disconnect to cease listening instead of pk_close

this version now supports IP over X.25; changes include setting
the X25_MBS_HOLD flag and preserving flags through incoming call cloning and aassociation

many fixes & changes -- add routine to glue or spit vc to route;
and routine to turn on, off dg listening in kernel;\

mark state before allowing dynamic pkcb's

note current state -- compiles, includes frob to glue socket to route.

this still isn't expect to work.

checkpoint -- this version compiles and represents most of
the changes to have ISO CONS be a kernel client of X.25; not tested!!!!

capture current work; fix minor bugs concerning packet lengths &
conventions; add routine to fragment datagrams into complete sequences.

this version compiles; completely untested

assign SCCS numbers for ``June'' beta tape; not yet tested.

checkpoint before changing pq structure to be a sockbuf for downq
and only retaining up method

periodic checkpoint against catastrophic loss

install combined copyright headers using sccs include for terms
