implement mocking of faked gen_fsm processes

[bharendt]

e.g. ?assertCalled({local, registered_name}, ?once ?inAnyState)
use eunit_mocked_gen_fsm module for that like eunit_mocked_gen_server is used for fake gen_server processes and check in eunit_mock:assert_called({GlobalOrLocal, GenXXXModuleName}, Times, Options, MODULE, LINE) whether the ?inAnyState or ?inState(StateName) option is given
