41aa0ba271 Fix if_timer logic so that there is always a timeout pending if there
are packets queued for transmission.

This driver is strange -- it never sets IFF_OACTIVE, so all
transmissions always cause a call to fxp_start. However, if the
link gets stuck, there was nothing to reset it, so there was still
a possibility of lockups.

4dfae5a5e8 Make sure that if_timer does not get reset if there are packets
still queued for transmission. This should solve the problem of
the device stalling on transmissions if some link event prevents
transmission.

There are other drivers which have the same problem and need to be
fixed in the same way.

eb538bfd64 Extend the effect of the sysctl net.inet.tcp.icmp_may_rst
so that, if we recieve a ICMP "time to live exceeded in transit",
(type 11, code 0) for a TCP connection on SYN-SENT state, close
the connection.

because there isn't one. Of course this code only possibly works

006f19e4f2 Remove ALT_BREAK_TO_DEBUGGER. This was inconsistent (both in form
and function) with existing configuration choices.  Arguably if
ALT_BREAK_TO_DEBUGGER was present, so should have been
BREAK_TO_DEBUGGER.  Regardless, it broke the option sort order in
these kernel configuration files.

c21c16a492 Add a makefile for building UFS as a module. Since it is of marginal
use it is not built by default, and there are currently bugs that
prevent UFS from being unloaded. Nevertheless it can be useful when
developing UFS code on network-booted machines.

3b3afe10a7 Oops, that was a heck of a lot more debugging left onthan I intended..
turn it off!

I don't know if people think that these debugging macros are worth keeping
or not but I'll keep them for a short while, while the danger of
queue stuffups in the (rather complicated) run queue code exists.

e602ba25fd Part 1 of KSE-III
The ability to schedule multiple threads per process
(one one cpu) by making ALL system calls optionally asynchronous.
to come: ia64 and power-pc patches, patches for gdb, test program (in tools)

Reviewed by:	Almost everyone who counts
	(at various times, peter, jhb, matt, alfred, mini, bernd,
	and a cast of thousands)

	NOTE: this is still Beta code, and contains lots of debugging stuff.
	expect slight instability in signals..

8b8aa9c1e6 To quote Peter:
The case in cpu_switch() where there isn't a higher priority thread
(choosethread() == curthread) uses r4 as the PCB context pointer. However, the
use of r4 after the label L2 is incorrect, since it was probably trashed by
the call to choosethread, and in any case was set up to curthread at the start
of the routine.

This condition will occur when an interrupt thread schedules a netisr, which
is a lower priority thread.

Another (probably unnecessary) difference is that I was paranoid about
register trashing, so I decided to save r2 and r13 as well.

6c2a062580 Many fixes to low-level trap and interrupt handling:
- Tidy up clock code.  Don't repeatedly call hardclock().
- Remove intrnames, decrnest and intrcnt from locore.s
- Coalesce all trap handling into a single stub that then calls a dispatch
  function.
