When the MSC has lost its state and issues a RESET, we should not only
clear all ongoing radio connections, but we should also stop any paging.
There's no point in paging a subscriber if the MSC doesn't know about
this paging anymore.

The call-back was needed inside the NITB to determine which part (CC,
SMS, ...) had triggered a given paging. A pure BSC doesn't need that
feature, so let's get rid of it.
The 'void *cbfn_data' is replaced with a 'struct bsc_msc_data *', as
all callers use it with that type.

This timer is started when a channel is allocated with an IMMEDIATE
ASSIGNMENT message. It is stopped when the MS has correctly seized the
channel. Ever since the early days of development we were using a very
long timeout to be on the safe side. However, in production networks
this is a terrible waste of resources, as we will occupy 10s worth
of air-time on one of our channels for each RACH request we receive.
The only scenarios where you might need something absurdly high as 10s
would be if you have 8s of RTT between your BTS and the BSC.

This is left over from the OsmoNITB days. We're defining and allocating
these MSC counters, but never actually using them. This also means that
the automatic counter export will list them, raising the expectation at
users that such counters could be used in OsmoBSC.
Let's remove them. They are in OsmoMSC, but not OsmoBSC.

Prepare for a future change that accesses bts->network during gsm_bts_alloc().
Currently, gsm_bts_alloc() takes a ctx parameter, and gsm_bts_alloc_register()
then gets the gsm_network pointer and sets bts->network to it. All callers
anyway pass gsm_network as ctx to gsm_bts_alloc(), and anything else would not
make sense anyway. So enforce passing exactly gsm_network to gsm_bts_alloc()
and already set the bts->network pointer from there.

In state prior to this patch, "3G Early Classmark Sending Restriction"
bit in SI3 rest octets was always set to H, which is a sane default as
the policy to send the information is then controlled by "Early
Classmark Sending Control" bit in the same octet.
However, it seems Quortus SoftCore can have some issues decoding the
option, so let's add a vty cmd to be able to disable it for those
having any issues.

osmo-bsc currently negotiates the RTP stream directly with the
BTS and reports back the RTP IP/Port on the BTS. This works fine
for a single BTS, but for Handover the port/ip pointing to the
MSC side must not change, so an entity in between the BTSs and
the MSC is required.
Integrate the mgcp-client and use osmo-mgw to switch the RTP
streams.

Fixes regression probably introduced in c696cc28.
For bts>0 logging doesn't show bts number correctly when printing lchan
identification string - it will always show it as "bts=0". The reason for
this is that the identification string is cached before bts->nr value is
set to a proper value.
This patch sets bts->nr as part of the first step of the bts structure
initialization, before caching happens thus making sure the cached
identification string is cached with the correct values.

This patch implements "Appendix B. Delivery Receipt Format" as specified
in the SMPP 3.4 specs. This string is conveyed in the SMS message as
data, and it is only meaningful to the ESME, for logging purposes. The
"submit date" and "done date" are not yet set, and other fields are just
sent with dummy values, so they are left to be finished as future work.
The new SMPP TLV tag TLVID_user_message_reference is added to the SMPP
messages inconditionally now since this information is required by
delivery-reports to associate the status-report with the original SMS.
