b6e49ed332 Remove the bus settle delay after reset code. It could cause an infinite 
loop.

Perform a "-Wall" cleanup which actually exposed two real bugs having to
do with operator precedence.

083bc8b2cc Add a spin lock that prevents the sequencer from attempting to add an 
entry to the QOUTFIFO when it is full.  This should eliminate the
"Timed out while idle" problems that many have reported.

In truth, this is somewhat of a hack.  Although are interrupt latency is
low enough that we should be able to always service the queue in time,
since each entry must be passed up to the higher SCSI layer for what can
be a large amount of processing (perhaps even resulting in a new command
being queued) with interrupts disabled, we need this mechanism to avoid
overflow.  In the future, these additional tasks will be offloaded to a
software interrupt handler which should make this hack unnecessary.

f8fc96b551 Fixed vnode corruption by undefined case in union_lookup(). When 
uerror == 0 && lerror == EACCES, lowervp == NULLVP and union_allocvp
doesn't find existing union node and new union node is created.

Sicne it is dificult to cover all the case, union_lookup always
returns when union_lookup1() returns EACCES.

2c060c765a Fix a traceroute problem in the CISCO HDLC mode. (cisco routers not 
returning ICMP_TIMXCEED)

use CISCO_UNICAST instead of CISCO_MULTICAST to send normal packets.
this is needed for packets to get processed by a cisco router,
but doesn't matter if a packet is just forwarded.
