Audio SAPI version 1 has been added recently in osmo-hnodeb.git
I860d18b80c1041bf63a1570d435e0568c0f6b01b.
Let's update our HNBLLIF emulation to support and use it.

A new Iuh CodecPort + Emulation is introduced to (de)mux RANAP and RUA
in the same SCTP socket.
The Iuh_CodecPort.ttcn file has currently a hack to be able to test
HNBAP, since titan seem to be reporting sinfo_ppid=0 when in fact it
received sinfo_ppid=20 (HNBAP).
A couple tests are added to validate HNBAP HNBRegister Request + Accept
or Reject. In current osmo-hnodeb state, both tests pass if run
separately, but fail if run sequentially since osmo-hnodeb still doesn't
re-connect properly after first test finishes and connection is dropped.
