dillon bb806c49bf Implement TCP bandwidth delay product window limiting, similar to (but
not meant to duplicate) TCP/Vegas.  Add four sysctls and default the
implementation to 'off'.

net.inet.tcp.inflight_enable	enable algorithm (defaults to 0=off)
net.inet.tcp.inflight_debug	debugging (defaults to 1=on)
net.inet.tcp.inflight_min	minimum window limit
net.inet.tcp.inflight_max	maximum window limit
