directly include only the header files needed. This reduces the
unneeded spamming of various headers into lots of files.
For now, this leaves us with very few modules including vnet.h
and thus needing to depend on opt_route.h.

As clearly mentioned on the mailing lists, there is a list of drivers
that have not been ported to the MPSAFE TTY layer yet. Remove them from
the kernel configuration files. This means people can now still use
these drivers if they explicitly put them in their kernel configuration
file, which is good.
People should keep in mind that after August 10, these drivers will not
work anymore. Even though owners of the hardware are capable of getting
these drivers working again, I will see if I can at least get them to a
compilable state (if time permits).
NET_NEEDS_GIANT. netatm has been disconnected from the build for ten
months in HEAD/RELENG_7. Specifics:
- netatm include files
- netatm command line management tools
- libatm
- ATM parts in rescue and sysinstall
- sample configuration files and documents
- kernel support as a module or in NOTES
- netgraph wrapper nodes for netatm
- ctags data for netatm.
- netatm-specific device drivers.

NET_NEEDS_GIANT, which will shortly be removed. This is done in a
away that it may be easily reattached to the build before 7.1 if
appropriate locking is added. Specifics:
- Don't install netatm include files
- Disconnect netatm command line management tools
- Don't build libatm
- Don't include ATM parts in rescue or sysinstall
- Don't install sample configuration files and documents
- Don't build kernel support as a module or in NOTES
- Don't build netgraph wrapper nodes for netatm
This removes the last remaining consumer of NET_NEEDS_GIANT.

the kernel by wrapping all targets for fake opt_*.h files in
.if defined(KERNBUILDDIR). Thus, such fake files won't be
created at all if modules are built with the kernel.
Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.

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.

example.
There is no manual page as yet, I will write one shortly.

message encoding and decoding stuff into the base module. All of this
is accessed by several of the NgATM modules and putting this into
atmbase reduceds the memory footprint.
