Reduce debugging output for netatalk routing events.

MFC after: 3 days

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).

/* -> /*- for license, minor formatting changes, insert COPYRIGHT into files

Imperfect synchronization solution to imperfect code: use a static 256
byte buffer in the stack for temporary printf results rather than a
global buffer without synchronization.

Compare pointers with NULL rather than 0, or treating them as boolans in
if statements.

at_rmx gets a $FreeBSD$ out of the deal also (this code appears to be
unused).

De-staticize and add prototype for main debug function. I'll turn
this into a DDB command in the next staticization run.

Staticize.

Fixed printf format errors.

Removed unused #includes.

Kernel Appletalk protocol support
both CAP and netatalk can make use of this..
still needs some owrk but it seemd the right tiime to commit it
so other can experiment.
