If an API user only has access to the ci FSM (which is managed via an opaque
struct), provide this function to obtain the backpointer to the parent endpoint
FSM, mostly to be able to call osmo_mgcpc_ep_cancel_notify() on it.
osmo-msc's rtp_stream FSM will use this in
I351bb8e8fbc46eb629bcd599f6453e2c84c15015.

There is a use-after-free problem if a 'notify' FSM as passed to
osmo_mgcpc_ep_ci_request() deallocates before the notify event has been
dispatched. To avoid that, add API to allow cancelling a notify.

Move mgw_endpoint_fsm from osmo-bsc here as osmo_mgcpc_ep_fsm. Apply various
renames for consistency. Use osmo_tdef from libosmocore instead of osmo-bsc's
(so far) local T_defs API.
Change T23042 to T2427001, which is a slightly less arbitrary number and
slightly more extendable in the future (2427 corresponds to the default MGCP
port at osmo-mgw, 001 is the first MGCP timer and so far the only one).
