Add gtk-docs for enum types that previously didn't have them.
Explicitly note the relationship between NetworkManager.h /
NetworkManagerVPN.h types and the corresponding introspection/*.xml
types.
- Remove list of authors from files that had them; these serve no
purpose except to quickly get out of date (and were only used in
libnm-util and not libnm-glib anyway).
- Just say "Copyright", not "(C) Copyright" or "Copyright (C)"
- Put copyright statement after the license, not before
- Remove "NetworkManager - Network link manager" from the few files
that contained it, and "libnm_glib -- Access network status &
information from glib applications" from the many files that
contained it.
- Remove vim modeline from nm-device-olpc-mesh.[ch], add emacs modeline
to files that were missing it.
NetworkManager.h, NetworkManagerVPN.h, and nm-version.h are part of
the libnm-util API, so move them to libnm-util.
include/ still contains headers that are strictly NM-internal (eg,
nm-glib-compat.h).
