Patch submitted.  Approval pending.

I've cleaned this up.  There were a couple defines/enums that needed to be
moved to nto-share/debug.h from nto-share/dsmsgs.h.  Now there is no
requirement for the remote header in any of the tdep stuff.

Note also that I've cleaned a few more things up, including copyright
headers on all files, etc.

Perhaps that combined with my changes will do the trick.
