Remove historical support for capturing IPX packets in the output path

using raw IPX sockets.  While functional, this support is disabled
using a flag that can't be changed from userspace, and google reveals
no documentation or use of that flag anywhere.  This eliminates a
potential lock order reversal and code reentrance issue in which the
output path reentered the input path in IPX.

An alternative to removal would be to use the netisr, as a comment I
added in 2005 suggests.  While this change is fairly straight-forward,
the lack of any consumers or the easy possibility of consumers (kernel
modification and recompile required) suggests that this is simply an
unused feature.

Update README to remove this TODO, and a TODO regarding IPX/IP
encapsulation which was also removed a few years ago.
