So that normal users who have PolicyKit authorization to edit system connections
can read secrets, move system connection secrets logic into the system connection
service from libnm-glib, and protect it with PolicyKit checks. Convert the
ifcfg-rh plugin over to using NMSysconfigConnection so that it can take advantage
of the new PolicyKit protection.
Fix a few problems... No plugin should return secrets in the GetSettings method,
which some plugins did. When that was committed in the commit "system-settings:
don't return secrets in the settings", it broke those plugins that didn't implement
GetSecrets. Each plugin can actually use the same code for GetSettings and
GetSecrets, so implement those generically in the NMExportedConnection class and
remove plugin-specific implementations that all did the same thing.
To match 'network' service behavior, which would perform reverse
address lookups when the HOSTNAME from /etc/sysconfig/network
was 'localhost' or 'localhost.localdomain'. Just name your machine
already.
0.7 requires dbus 1.1 or greater (for system bus activation), so make that
explicit, and remove compat code for D-Bus 0.6 and earlier. Consolidate
the various glib pkgconfig checks into one, since most anything will require
gthread, glib, and gobject anyway. Fixup the docs makefile to be more
automake-compatible and let 'make clean' actually work correctly when
docs are built.
Clean up handling of "special" keys in keyfiles, ie ones that
need more processing than the basic GKeyFile API supports. Add
MAC address reading (writing support to come).
Additionally, add some test bits for the keyfile plugin that get
run on 'make check'.
Previous code forgot to clear a temporary variable when reading IPv4
addresses from ifcfg files, and when the value being read wasn't in the
ifcfg file, it could set wrong values in the connection for that variable
even though it didn't exist.
