This changes from a line discipline to the tty_hooks mechanism. Data will come
in directly via rint_bypass and sent to the peer node in a single mbuf.
As line disciplines are no longer used a new netgraph command called
NGM_TTY_SET_TTY is used to attach the tty. This takes a pointer to to the open
file descriptor of the tty and registers the tty hooks. When the tty disappears
the node will shutdown.

should have been removed before 7.0, but 8.0 will do.

Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator
macros, and CURVNET_SET() context setting macros, all currently
resolving to NOPs.
Prepare for virtualization of selected SYSCTL objects by introducing a
family of SYSCTL_V_*() macros, currently resolving to their global
counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().
Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).
All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

It turns out I overlooked some function prototypes that were actually
TTY related, but were stored in <sys/conf.h> to implement the D_TTY
flag. Remove these prototypes now that they don't exist anymore.

the gvinum header in fields of fixed size and in a big endian byte order
rather than the size and byte order of the actual platform.
Note that the change is backwards compatible with the old gvinum configuration
format, but will save the configuration in the new format when the 'saveconfig'
command is executed.

- Update or remove comments that were left over from the original
soreceive_generic() implementation. Quite a few were misleading in the
context of the new code.
- Since soreceive_dgram() has a simpler structure, replace several gotos
with a while loop making the invariants more clear.
- In the blocking while loop, don't try to handle cases incompatible with
the loop invariant (since m is always NULL, don't check for and handle
non-NULL).
- Don't drop and re-acquire the socket buffer lock unnecessarily after
sbwait() returns, which may help reduce lock contention (etc).
- Assume PR_ATOMIC since we assert it at the top of the function.

In my previous commit I disabled pkill(1)'s automatic prepending of the

both possible device names when called.
