appletalk: move to staging
For all I know, Appletalk is dead, the only reasonable use right now would be nostalgia, and that can be served well enough by old kernels. The code is largely not in a bad shape, but it still uses the big kernel lock, and nobody seems motivated to change that. FWIW, the last release of MacOS that supported Appletalk was MacOS X 10.5, made in 2007, and it has been abandoned by Apple with 10.6. Using TCP/IP instead of Appletalk has been supported since MacOS 7.6, which was released in 1997 and is able to run on most of the legacy hardware.
