We must have initialized e.g. the NS protocol stack before calling
handle_options(), as that might want to dumpy the VTY XML, and it
can obviously only dump those nodes that are registered at that
point.

Move 'doc' subdir further down to "make sure" the osmo-bsc binary is built
before the docs
Rremove sgsn_vty_reference from the source tree.
In manuals//Makefile.am use the new BUILT_REFERENCE_XML feature recently added
to osmo-gsm-manuals, and add a build target to generate the XML using the new
osmo-sgsn --vty-ref-xml cmdline switch.

msgid2mmctx() was already being called for signalling messages in
gsm0408_gprs_rcvmsg_gb() before calling gprs_gb_recv_pdu(), but it was
not called in sndcp_llunitdata_ind().
Let's move msgid2mmctx() inside gprs_gb_recv_pdu() since we want to
always update the nsei+bvci, regardless of message containing data or
control content.
This commit fixes the scenario where an MS changes to a new cell (PCU)
and then continues transmitting UL data. Prior to this patch, the SGSN
kept sending DL content to the old cell (PCU nsei+bvci) instead of the
new one even after the MS transmitted Ul content fro mthe new cell.

The call gprs_ns2_dynamic_create_nse has been removed because it
was a workaround for the old/dropped vty api.

The last remaining functin of the SGSN code base we used was
gprs_gb_parse_tlli().
Let's simply copy this function over and become self-contained.
This would allow migrating osmo-gbproxy to a separate repository.

If a radio status message contains a TMSI it should be routed as if it
was a TLLI. Convert the TMSI to (foreign) TLLI so NRI-routing works.
Both foreign and local TLLIs are routed the same.

Some code was missing to support PAGING_REJECT and DUMMY_PAGING_PS over both PTP
and signalling. This commit adds the missing pieces, notably:
* Use and route according to the IMSI cache for paging on PTP
* Ensure DUMMY_PAGING_PS is broadcast if no routing area is included

DPCU is defined in debug.h, but never registered as log subsystem,
so we shall not use it. Also remove other similar "orphan" log
subsystems from debug.h

When SGSN pooling is enabled we need to route some responses based on
IMSI back to the correct SGSN, e.g. PAGING_PS_REJECT.
The IMSI cache keeps track of this IMSI <-> NSE(SGSN) mapping.

The range of SUSPEND/RESUME timers T3/T4 is up to 10s so we should keep

When routing a SUSPEND/RESUME we need to keep track of where it came
from so we can send the (N)ACK back to the correct BSS. Use the TLLI
which is present in both messages to cache and retrieve the correct BSS.
A timer runs every two seconds and expires entries that are older than
the timeout (hardcoded to 5 seconds for now).
