Merge branch 'zecke/features/osmux-reliability'
Not verified that the audio handling is working. I saw a circuit
set-up of the call though.

osmux: Make sure that bigger Osmux ids actually fit
We put a signed integer into this string but did not account
for the newline and for the terminating NUL of the string. Add
the newline to the string and add one for NUL. Spotted while
accidently having a CID of 255.

osmux: Remember the allocated CID and make sure it is released
There appears to be a leak of CIDs:
<000b> mgcp_osmux.c:544 All Osmux circuits are in use!
There are paths that a CID had been requested and never released
of the NAT. Remember the allocated CID inside the endpoint so it
can always be released. It is using a new variable as the behavior
for the NAT and MGCP MGW is different.
The allocated_cid must be signed so that we can assign outside
of the 0-255 range of it.
Fixes: OW#1493

commit 20626dde8fd04c2ded3788a8417ea67abf17c4cf
Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com>
Date: Fri Oct 2 18:15:18 2015 +0200
osmux: Enforce Osmux only global and per BSC configuration
Extend the osmux only setting from the MGCP MGW to the NAT. This
is applied when an endpoint is allocated and/or when the allocation
is confirmed by the remote system.
Not tested. The impact should only be when the new option is
being used.

osmux: Allow to enforce using Osmux for the client
Some systems only want to use Osmux. In case only Osmux
should be used fail if it has not be offered/acked.
Client:
Verified On, Off and Only with X-Osmux: 3 and without this field.
<000b> mgcp_protocol.c:823 Osmux only and no osmux offered on 0x14
<000b> mgcp_protocol.c:884 Resource error on 0x14
NAT:
Not tested and implemented

osmux: Add introspection for osmux.
* Print number of used CIDs for the system
* Hopefully this is just the beginning

commit b45e4d80b6b6b6bb597ccb3a14c16395481f7816
Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com>

osmux: Do not divide the number of bytes by eight.
sizeof(uint8_t) == 1 and there is no need to create an array
with 16 bytes and then only use the first two of them. This
means the CID range is from 0 to 127 and we should be able
to extend this to 256 by changing the array size to 32. Update
the testcase now that we can have more than 16 calls with Osmux.

osmux: Test cid allocation and de-allocation
* Test that one can get an id
* That they are assigned predicatble right now
* That returning them will make the number of used ones go down
* That allocating more will fail
