make kernel includes standard

need to include systm.h to get min and max

1.) don't set retransmit timers in tp0; 2.) tone down panic:tp_rsyflush

misunderstood function of kernel variable ``ticks'';
need a different one for cheap timer.

make code more similar to TCP (use RANGESET & REXMTVAL macros);
allow for faster initial zero window probes

these changes reflect the TCP algorithm for round trip timing
(not yet tested)

adopt TCP's policies concerning acks & (among others) use the fast

now that SO_RCVBUF calls down, calculate maxcredit, and use in
LOCAL_CREDIT macro.

changes to get rid of RTC structure; move packetizing to here.

new ack strategy from mostek@cray

minor changes to compile under both new and old vm systems

new copyright; att/bsd/shared

fix retransmission timer

mitre decbit changes

fixes to tracing and avoiding silly window between
