two versions of a fix for an mbuf leak. The first one is probably right,
but a BSDI customer has not confirmed that problems went away. The second
version should be safe. The mbuf leak happens when RST is received on
a connection after sosend checks the state, then drops spl while doing
a copyin. A send of [100-208] bytes on a local connection would always
hit this if the other end had closed.

much longer keepalive timer (don't start probes for 2 hr);
fix input window test again (accept acks from FINS at left edge and responses
to keepalives, but dropafterack otherwise; also fixes Phil Karn's problem
with failure to respond to new SYN to left of window); can't use tcp_drop
after RST, or we'll send RST in response
