Node constructor methods are supposed to be called in syscall
context always. Convert nodes to consistently use M_WAITOK flag
for memory allocation.

When calling panic(), always pass a format string.

Retire the MALLOC and FREE macros. They are an abomination unto style(9).

/* -> /*- for license, minor formatting changes

Consistently use __inline instead of __inline__ as the former is an empty macro
in <sys/cdefs.h> for compilers without support for inline.

Switch to using C99 sparse initialisers for the type methods array.
Should make no binary difference.

Finish driving a stake through the heart of netns and the associated
ifdefs scattered around the place - its dead Jim!

The SMB stuff had stolen AF_NS, make it official.

Back out M_* changes, per decision of the TRB.

Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.
Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

Update to C99, s/__FUNCTION__/__func__/,
also don't use ANSI string concatenation.

NULL commit due to misunderstanding "cvs commit -m <blah>". The
previous log message "/home/brooks/ng_gif.message" should have read:

Add a pair of new netgraph nodes. The ng_gif node is like ng_ether
except that it works on gif interfaces. The ng_gif_demux node attaches
to an ng_gif node to allow separate processing or discarding of
different types of encapsulated traffic.

The initial commit contained an error in the license, this is the
correct one.
