9967cafc49 Correct mbuf packet header propagation. Previously, packet headers
were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a  "copy" operation.  This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain.  This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.

These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block.  This
introduces an incompatibility with openbsd which we may want to revisit.

Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them.  We may want to support this;
for now we watch for it with an assert.

Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

fe1c49fbba - Chainsaw the storage pool code. This was being used by a bunch of code
within the HARP atm stack and the hea and hfa device drivers, but since
  all of these systems were changed to use UMA zones, there is no use for
  the api any longer.

b6037a7953 - Turn the hea and hfa HARP storage pools into UMA zones and insert
the necesary uma_zcreate() and uma_zdestroy calls into module loading
  handler and the device attach handling.
- Change the related HARP netatm code to use UMA zone functions when
  dealing with the zones that were formerly the ATM interface (hea, hfa)
  storage pools.
- Have atm_physif_freenifs() now get passed an uma_zone_t so that we can
  properly free the allocated NIF's back to their zone.

This should be the last commit to remove any code that makes use of the
netatm storage pool api.  I will be removing the api code within the near
future.

560edda366 - Finish the uni part of the storage pool cleanup. There should now only
be a few bits left to clean from the HARP code in terms of what is using
  the storage pools; once that's done, the memory management code can be
  removed entirely.

  This commit effectively changes the use of dynamic memory routines from
  atm_allocate, atm_free, atm_release_pool to uma_zcreate, uma_zalloc,
  uma_zfree, uma_zdestroy.

243917fe3b Lock down a socket, milestone 1.
o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a
  socket buffer. The mutex in the receive buffer also protects the data
  in struct socket.

o Determine the lock strategy for each members in struct socket.

o Lock down the following members:

  - so_count
  - so_options
  - so_linger
  - so_state

o Remove *_locked() socket APIs.  Make the following socket APIs
  touching the members above now require a locked socket:

 - sodisconnect()
 - soisconnected()
 - soisconnecting()
 - soisdisconnected()
 - soisdisconnecting()
 - sofree()
 - soref()
 - sorele()
 - sorwakeup()
 - sotryfree()
 - sowakeup()
 - sowwakeup()
