add mactime plugin unit / code coverage tests

The unit and code coverage tests are boring. The rest of the patch involves test and packet-generator infra cleanups. Teach the "make test-xxx" family of targets to set the api test plugin path correctly, to make "binary-api <api-message-name> <args>" debug CLI commands work correctly in the "make test" environment. Unfortunately involves both the top-level and test Makefiles. Add a minor pg cli feature, a CLI to manually set s->sw_if_index[VLIB_TX]. Consider the case where one configures an interface with both a device-input and an output feature. To test the output feature using the pg, it's necessary to inject packets into the interface output node with both b->sw_if_index[VLIB_TX] and b->sw_if_index[VLIB_RX] set correctly. For example: packet-generator new { name tx limit 15 size 128-128 interface local0 # rx: device input feature not configured on local0 tx-interface loop0 # tx: output node requires b->sw_if_index[VLIB_TX] node loop0-output data { hex 0x01005e7ffffa000dead0000008000102030405060708090a0b0c0d0e0f0102030405 } } Fix a longstanding bug in the packet generator stream setup. Remove kludges which set b->sw_if_index[VLIB_TX] to ~0 [in multiple places] instead of using the stream value s->sw_if_index[VLIB_TX], and setting THAT datum correctly.
