Re-add callout_active(), in a way compatible with the FreeBSD version, and use
...
it in the TCP stack to test which of the REXMT or PERSIST timer is in use.
This fixes a race condition that could cause "panic: tcp_output REXMT". See
tech-net for details.

Use callouts for TCP timers, rather than traversing the list of
...
all open TCP connections in tcp_slowtimo() (which is called 2x
per second). It's fairly rare for TCP timers to actually fire,
so saving this list traversal is good, especially if you want
to scale to thousands of open connections.

Split tcp_timers() into multiple functions, one for each timer,
...
and call it directly from tcp_slowtimo() (via a table) rather
than going through tcp_userreq().
This will allow us to call TCP timers directly from callouts,
in a future revision.

Expose the delayed ACK timer as net.inet.tcp.delack_ticks.

Use the monotonically increasing slow timer timestamp provided by
...
the protocol dispatch layer for TCP timers. This saves having to
modify a potentially large number of timer values (which were shorts,
and expanded to ... a lot of code on the Alpha).
