dbus-c++: report DBUS_ERROR_OBJECT_PATH_IN_USE error
This CL modifies ObjectAdaptor::register_obj() to throw an
ErrorObjectPathInUse exception if it fails to register a handler for a
given path in the DBus object hierarchy (i.e. upon a
DBUS_ERROR_OBJECT_PATH_IN_USE error).
BUG=chromium:392903
TEST=Tested the following:
1. `emerge-$BOARD dbus-c++`
2. Manually modify shill to register a DBus adaptor with the same
object path twice, and verify that an ErrorObjectPathInUse exception
is raised.
