BTS_Tests.ttcn: fix TRXC port mapping between test_CT and ConnHdlr
Before this patch, sending special TRXC commands to FakeTRX, such as FAKE_TOA and FAKE_RSSI, from ConnHdlr resulted in a receive timeout waiting for the response. As it turned out, both the test_CT and the ConnHdlr have a TRXC port, as depending on the test one would want to globally control it from test_CT or from within a ConnHdlr. However, only one of the two should be active (connected) at any given point in time. Otherwise we'll have two UDP sockets on the same bind port, and it's more or less random on which of them it ends up. Let's add an optional parameter 'trxc_comp', which would indicate whether we need to control TRXC from ConnHdlr or not. Let's get rid of both f_trxc_connect() and f_main_trxc_connect(), which basically do the same, but run on different components. Change-Id: Ie7d311bf8f03bf9b1d29b5bb28ffad793f215fd1 Closes: OS#4039
