Previously, we built a second copy of libnm-glib that was hacked to
use the session bus rather than the system bus, for use by the test
programs. Rather than doing that, just have test-nm-client explicitly
override the choice of bus. (test-remote-settings-client was actually
already doing this, although it leaked the bus after.)
- 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purpose except to quickly get out of date (and were only used in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.
A number of places in the code need to get a connection to NM through
D-Bus, and that connection could be either a shared bus connection or
a private connection. Consolidate that logic.
Unfortunately only dbus-glib >= 0.100 correctly supports private
connections (commit 8b7e4a1c4ae055864e26db4addbcc2dc38ee6963 fixes
this problem) so the private connection functionality is not enabled
for older dbus-glib versions.
