android/tester: Add generic hook to handle pdu exchange

This allows tester-main to register hooks for certain CID to
automatically perform pdu exchange by registering array of pdu pairs
(request_pdu, response_pdu). When end_pdu is used instead of
request_pdu, response is sent immediately without incoming pdu
verification. A pair with end_pdus set as request and response is
considered as the end of pdu pairs array.

This callback can also handle sdp request<->response while transaction
ID for the response is swaped to match the one from SDP request.

'emu_l2cap_cid_data' is used to pass tha appropriate data to the hook
mechanism. It is similar to 'emu_cid_data" used in other testers and
eventually will replace those.
