This patch adds a new gdbus helper to notify the clients that
GetManagedObjects reply was received and the last proxy has been
informed previously by the proxy_added callback.
The current bitshift logic in idmap incorrectly uses
the literal 1 for the value to shift in idmap_alloc(),
idmap_take(), and idmap_alloc_next(). This causes the
resulting value to be an int instead of a long, which
results in the wrong bit being set once the number of
bits to shift operand exceeds sizeof(int). Also
on some platforms, the behavior of the left bitshift
operator is undefined when this overflow occurs.
Commit abfc2b0dd5c3e33abfdf1a815b16d492c1751c06 attempted to fix a crash
related to improper reference counting, but the main issue was that the
reference was taken only during the function call (which is usually
unnecessary for single thread), but still passed a pointer to
DBusConnection to a function that is called by the mainloop. This left a
window where the DBusConnection can be destroyed.
Fixes this crash on unit/test-gdbus-client:

For devices which are not 'real' phone modems, the voicecall
initialization can happen outside of the pre-sim state. In this case
the voicecall atom detection logic fails. Try to detect the voicecall
atom separately, and register the profile if the SIM atom is already
present and in state 'READY'.
For all other cases, the previous logic still applies.
"Warning: if the connection is disconnected or you try to send Unix file
descriptors on a connection that does not support them, the
DBusPendingCall will be set to NULL, so be careful with this."
Check this in g_dbus_send_message_with_reply so that callers don't need
to double check for NULL if g_dbus_send_message_with_reply returned
TRUE.
This also fix crash if passing FD over D-Bus is blocked e.g. by SELinux
policy.

This is normally a bug in some application using the D-Bus library.
As we won't allow any card to be registered when the kernel doesn't
support defer_setup, we don't need to have the listening SCO socket
open in this case.
If the kernel doesn't support defer_setup for SCO, we shouldn't allow
cards to be registered, because in that case we won't be able to
properly send the file descriptor to the Agent.
