lib: Rename CACEP to CEP and set conngmr timeout0.21.2

The Common Application Connection Establishment Protocol (CACEP) is a
RINA construct associated with the Common Distributed Application
Protocol (CDAP). We dropped CDAP as O7s sees connection establishment
as common to all applications (though it can be a nop). The wiki
already refers to this as (O7s) Connection Establishment Protocol
(CEP).

The connection manager will now timeout waiting for CEP messages to
avoid hanging forever, configurable at build time via
CONNMGR_RCV_TIMEOUT.
