This allows different parts of the code to hook to some signals which
allow start/stopping processes based, for instance, on whether C0 is
available or not.
This can be later used by paging or CBSP code. Also ACC code can be
ported to this new system (acc_ramp_nm_sig_cb()).
Same signal can be used for other NM objects, but is left unimplemented
until there's use for them.

This is needed in order to to proper feature support verification for
IPv6 when configuring the NSVC.
Before this patch, there could be a race condition where NSVC FSM
checked for BTS feature BTS_FEAT_IPV6_NSVC before it was negotiated
through BTS Get Attributes (Ack).

Before this patch, Get Attributes was sent quicklyafter the OML link
became up, even if the BTS/BB_TRANSC objects were still powered off,
which is wrong since attributes should only be available after the
objects transition out of the Power off state.
Furthermore, information about get attr response already received will
be required in future patches to delay NSVC setting.
