Don't let ether_input() to do the bridging work, i.e. change input iface,

o  IFF_MONITOR support.
o  Assumption that ether_input() is called with input iface's serializer
   held.
o  Per interface input packets and bytes statistics.

Let the bridge(4) handle the input iface change, which is centralized
at the end of bridge_input() after leaving bridge(4) iface's serializer.
We call ifnet.if_input() when handling iface change, instead of skipping
the "upper" half of ifnet.if_input() as we did originally; the assumption
that "upper" half of ifnet.if_input() does nothing according to input iface

endian detect bits from sm_msgid to sm_proto.  This allows the exact same
sm_msgid supplied in a command to be used in the reply and frees up bits
in the msgid that were previously going to be used for the protocol.
A separate protocol field also makes it a lot easier for the recipient
to check that the protocol is compatible with its expectations.

Implement a message based userland API and implement a syslink pair feature

buffering limits, non-blocking I/O (but not select support yet), check

* Abstract-out the message port initialization code and clean up related

* Add a new backend called the 'spin' port backend.  This backend can be
  used if a message port might be drained by several different threads.
  For example, this would allow us to use a message port as part of a
  file pointer / file descriptor construct.

* Add a boot-time tunable, lwkt.use_spin_port (defaults to off) which
