3f89da1440 Clean up DDP layer netatalk code:
- General style(9) cleanup -- white space, braces, line wraps, etc.

- Annotate a lack of synchronization the global route cache if the input
  routine is invoked with parallelism.

- Remove unused debugging code.

c4c1a3359a Break out my copyrights with our 2-clause BSD license from the UMich
copyright, which while similar, is different.

7beaaf5cd2 Complete break-out of sys/sys/mac.h into sys/security/mac/mac_framework.h
begun with a repo-copy of mac.h to mac_framework.h.  sys/mac.h now
contains the userspace and user<->kernel API and definitions, with all
in-kernel interfaces moved to mac_framework.h, which is now included
across most of the kernel instead.

This change is the first step in a larger cleanup and sweep of MAC
Framework interfaces in the kernel, and will not be MFC'd.

c39858036f Acquire socket receive buffer mutex before appending and then waking up
a receive socket in DDP.  This reduces the number of mutex operations
required to deliver to a socket by two, and is the model used in other
protocols.

199b1160c6 Inline umich license from COPYRIGHT to make it clear what license the
umich copyright is asserting.

Clarify that the copyright I'm asserting is the standard Berkeley
license.

Remove Giant assertions from AARP and DDP input routines.

f1bc833e95 Socket MAC labels so_label and so_peerlabel are now protected by
SOCK_LOCK(so):

- Hold socket lock over calls to MAC entry points reading or
  manipulating socket labels.

- Assert socket lock in MAC entry point implementations.

- When externalizing the socket label, first make a thread-local
  copy while holding the socket lock, then release the socket lock
  to externalize to userspace.

e7287c638a Rename 'at_ifaddr' list to 'at_ifaddr_list' so that the variable is

c4f5b78e26 Compare pointers with NULL rather than 0, or treating them as boolans in
if statements.

at_rmx gets a $FreeBSD$ out of the deal also (this code appears to be
unused).

83a23fd2a4 Also modify ddp_input.c with the following changes previously applied
to other files in netatalk:

  Log:
  Since I have my hands all over netatalk adding locking and restructuring
  it, cinch the file's style closer to style(9) with regard to parenthesis:

    s/( /(/g
    s/ )/)/g
    s/return(/return (/g
    s/return 0/return (0)/
    s/return 1/return (1)/

7f3b205cb8 o add a flags parameter to netisr_register that is used to specify
whether or not the isr needs to hold Giant when running; Giant-less
  operation is also controlled by the setting of debug_mpsafenet
o mark all netisr's except NETISR_IP as needing Giant
o add a GIANT_REQUIRED assertion to the top of netisr's that need Giant
o pickup Giant (when debug_mpsafenet is 1) inside ip_input before
  calling up with a packet
o change netisr handling so swi_net runs w/o Giant; instead we grab
  Giant before invoking handlers based on whether the handler needs Giant
o change netisr handling so that netisr's that are marked MPSAFE may
  have multiple instances active at a time
o add netisr statistics for packets dropped because the isr is inactive

04e28d5a81 Update netisr handling; Each SWI now registers its queue, and all queue
drain routines are done by swi_net, which allows for better queue control
at some future point.  Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

60c2032dc8 Introduce experimental support for MAC in the AppleTalk/EtherTalk stack.
Label link layer mbufs as they are created for transmission, check
mbufs before delivering them to sockets, label mbufs as they are created
from sockets, and preserve mbuf labels if mbufs are copied.

92d8381dd5 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()

89ec521d91 Revert the change of #includes in sys/filedesc.h and sys/socketvar.h.
Requested by:	bde

Since locking sigio_lock is usually followed by calling pgsigio(),
move the declaration of sigio_lock and the definitions of SIGIO_*() to
sys/signalvar.h.

While I am here, sort include files alphabetically, where possible.

26fcba4c5a Move the *intrq variables into net/intrq.c and unconditionally
include this in all kernels.  Declare some const *intrq_present
variables that can be checked by a module prior to using *intrq
to queue data.

Make the if_tun module capable of processing atm, ip, ip6, ipx,
natm and netatalk packets when TUNSIFHEAD is ioctl()d on.

827244dc7a Fix various problems with netatalk kernel support.
Some of these changes are a bit rough and will become
more polished later.  the changes to if_ethersubr should largely be moved
to within the appletalk code, but that will happen later.
A few of these were related to network-byteorder problems,
and more were related to loopback failures.
