547d34736b Major overhaul.
List of functional changes:
   - Make a single device per single node with a single hook.
     This gives us parrallelizm, which can't be achieved on a single
     node with many devices/hooks. This also gives us flexibility - we
     can play with a particular device node, not affecting others.
   - Remove read queue as it is. Use struct ifqueue instead. This change
     removes a lot of extra memcpy()ing, m_devget()ting and m_copymem()ming.
     In ng_device_receivedata() we enqueue an mbuf and wake readers.
     In ngdread() we take one mbuf from qeueue and uiomove() it to
     userspace. If no mbuf is present we optionally block. [1]
   - In ngdwrite() we create an mbuf from uio using m_uiotombuf().
     This is faster then uiomove() into buffer, and then m_copydata(),
     and this is much better than huge m_pullup().
   - Perform locking of device
   - Perform locking of connection list.
   - Clear out _rcvmsg method, since it does nothing good yet.
   - Implement NGM_DEVICE_GET_DEVNAME message.
   - #if 0 ioctl method, while nothing is done here yet.
   - Return immediately from ngdwrite() if uio_resid == 0.

 List of tidyness changes:
   - Introduce device2priv(), to remove cut'n'paste.
   - Use MALLOC/FREE, instead of malloc/free.
   - Use unit2minor().
   - Use UID_ROOT/GID_WHEEL instead of 0/0.
   - Define NGD_DEVICE_DEVNAME, use it.
   - Use more nice macros for debugging. [2]
   - Return Exxx, not -1.

 style(9) changes:
   - No "#endif" after short block.
   - Break long lines.
   - Remove extra spaces, add needed spaces.

a835396035 A node that creates a device entry in /dev (yay devfs)
so that /dev/mumble can be the entrypoint to some networking graph,
e.g. a tunnel or a remote tape drive or whatever...

Not fully tested (by me) yet.
