There is no need to have multiple separate return statements for error
cases in a sequence of operations. In addition, there is not much point
in "converting" boolean return values with "if (!res) return FALSE;
return TRUE;" style constructions.

By default, dbus_connection_dispatch() will call _exit() if the bus
connection has been closed. This caused wpa_supplicant to terminate
without properly cleaning up after itself.
To ensure that we terminate cleanly when the messagebus terminates,
override the exit_on_disconnect behavior and install a filter to handle
libdbus's "Disconnected" signal.

The perror() calls do not make much sense with libdbus functions and
wpa_printf() would really be used for all error printing anyway. In
addition, many of the error messages on out-of-memory cases are not
really of much use, so they were removed. This is also cleaning up
some of the error path handling to avoid duplicated code.
This was mostly identical code that had been copied for the new D-Bus
API implementation and as such, should really have been shared from
the beginning. In addition, the copied code ended up generating
interesting stack traces since the actual D-Bus connection was being
shared even though the pointer to it was stored in two distinct
data structures. The old D-Bus code ended up dispatching some
D-Bus callbacks which ended up running the new D-Bus code.
Since the private context pointers were mostly identical, everything
seemed to more or less work, but this design was just making things
more complex and potentially very easy to break.
