Cleanup of netatalk atalk layer includes, protocol definitions, and routing: - style(9) cleanup -- white space, braces, etc. - Make include guards consistent with our more general naming convention. - Rearrange and complete forward structure declarations in at_extern.h, remove testing of guards of various other include files to protect function declarations. This leaves an ifdef _KERNEL in at_var.h, but from inspection it seems likely that this file is not actually safe for inclusion in user space still. However, since it's not included from within src/ so this does not appear to be an issue (ifconfig, etc, have migrated to the generic cross-protocol ioctls for address operations).

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

extern struct rwlock at_ifaddr_rw;

Add a global rwlock, at_ifaddr_rw, to protect the global netatalk address lists, at_ifaddr_list. Acquire the lock, and use ifaddr refcounts where necessary, to close most known address-related races in netatalk. Annotate one potential race in at_control() where we acquire an ifaddr reference, drop the global lock, and scrub the address from the ifnet before re-acquiring the global lock, which could allow for a writer-writer race.
