Use libosmotrau for RTP support
...
This only implements creating, binding, connecting and free'ing RTP
sockets, not yet anything regarding receiving or transmitting codec
frames on them.
You will need the rtp branch of libosmocore for libosmotrau

RSL: fix transmission of RR ciphering mode command via LAPDm
...
We didn't correctly format the RSLms message that went into LAPDm,
causing LAPDm to drop the message.

update the HACK to delay the fake CIPHERING MODE COMPLETE
...
When seinding the fake CIPH MOD COMPL, we should wait a bit, as otherwise it
will reach the MSC _before_ we ever get the (still unencrypted) CLASSMARK
update from the MS.

This is not full encrpytion support, the bts-model part still

sysmbts L1 if: implement 'dead DSP L1 detection'

we ever do not receive any MPH-TIME.ind primitives from L1 within
that time frame, we stop the process (and will be re-spawned)

fix BTS initialization order
...
The sequence is as follows:
0) start osmo-bts
1) start connection attempts to BTS
2) issue L1-RESET.req
3) receive L1-RESET.conf
4) issue RF-ACTIVATE.req
5) receive RF-ACTIVATE.conf
6) receive attributes for TRX
7) receive opstart for TRX
8) issue MPH-INIT.req
[...]
The important point here is: We don't want the BSC to set TRX attributes or do
TRX opstart before our RF related hardware is initialized.

Fix support of SDCCH4
...
In SDCCH4, we use lchan number 0...3 for the SDCCH/SACCH, and
we statically use lchan[4] as the dummy for activating the CCCH
L1 SAPIs.
In order to make combined and non-combined CCCH orthogonal, we simply
also use lchan[4] in that case. On a 'pure' CCCH, therefore lchan
0..3 are unused and 4 is the actual CCCH.
