This allows us to add a new "hnb-policy closed", which means we do not
accept any random HNB connection anymore, but only those whose identity
is pre-configured explicitly using administrative means.
Furthermore, this new data structure will allow us (in future patches)
to keep persistent data like uptime / downtime of each HNB.

Allow configuring specific Network Instance names for the Core and
Access sides, to send to the UPF, to allow the UPF to pick the proper
network interface to create GTP tunnels on.
Add VTY cfg 'hnbgw' / 'pfcp' / 'netinst (access|core) NAME' to allow
configuring Network Interface values to send in PFCP. These are "dotted"
domain name strings, as in APN.
Add these Network Interface names to the PFCP messages' detection as
well as forwarding rules, each one indicating the side that it is
detecting on or forwarding to.
This helps lift osmo-hnbgw's PFCP support out of lab situations to a
proper production scenario, where the core and access networks are in
separate subnets, with osmo-hnbgw + UPF as the gateway.
For example, in osmo-hnbgw, configure
hnbgw
pfcp
netinst access my-ran
netinst core my-core
and in osmo-upf, configure
netinst
add my-ran 10.9.8.7
add my-core 1.2.3.4
In effect, all GTP tunnel endpoints towards the Access side will be
bound on 10.9.8.7, and all GTP tunnel endpoints towards the Core side
will be bound on 1.2.3.4.

So far, we had no pfcp.vty test, because PFCP support is built
conditionally, and the pfcp.vty test would always fail without PFCP
support.
Add a pfcp test for the VTY, conditionally: use suffix .vty.with_pfcp to
identify tests that need PFCP support, and run those only when
configured with --enable-pfcp.

consisting of 7 bytes (1byte IDP/AFI, 2byte ICP, 4 byte IPv4 address) insetad

When we check for an assignment failure in a RAB AssignmnetResponse, we
use decode_rab_flitms_from_resp_ies to search through the list of RAB
FailedItemsIEs for the RAB id we want to check. In case of failure, we
get a positive index back from this function. We then know that the RAB
that we checked for has failed bcause it was in the FailedItemsList.
In that case, we also must free the RAB FailedItemsIEs that
decode_rab_flitms_from_resp_ies has decoded. At the moment we also free
the RAB FailedItemsIEs also when decode_rab_flitms_from_resp_ies returns
with a negative return code, which may mean that the RAB was not found
or some other error occured. In this case we must not free since then
no valid RAB FailedItemsIEs are allocated.

According to 3GPP TS 25.413 8.26.2.2, "The RNC shall include the Global
RNC-ID IE in the RESET message." To be able to do that, osmo-hnbgw needs
to know the local PLMN.
Introduce explicit knowledge of the local PLMN by config, and use this
configured local PLMN in places where the local PLMN was so far derived
otherwise.
Subsequent patches will separately add the RNC-ID to the RANAP RESET
messages.
Since the PLMN is required to send correct RESET and RESET ACK, include
the new 'plmn' config item in all example configurations.

Implement cnlink FSM. This is a copy of osmo-bsc/bssmap_reset.c, except
for the connection success/failure counting.
The reason to exclude the CONN_CFM_FAILURE/_SUCCESS: it is a rather
experimental feature and should probably rather be covered by PCSTATE
notifications and protocol layer timeout tuning (e.g. SCCP ia timers).

Get a handle on how osmo-hnbgw currently auto-configures itself, by
running vty tests with a couple of config files that have various levels
of omitted config items that are to be auto-configured.
These tests serve to ensure continuity and compatibility by upcoming
cnpool patches. They will show how the configuration changes / doesn't
change in all the right ways.
Uncover one bug in osmo-hnbgw: local point-code setting is discarded by
osmo-hnbgw startup when there are no SCCP address book entries in use.

easier to read and maintain in form of a cfg file.

This option should be used for any executables which are used only
for testing, or for generating other files and are consequently never
installed. By specifying this option, we are telling Libtool that
the executable it links will only ever be executed from where it is
built in the build tree. Libtool is usually able to considerably
speed up the link process for such executables.

Large RAN installations may benefit from distributing the RTP voice
stream load over multiple media gateways.
libosmo-mgcp-client supports MGW pooling since version 1.8.0 (more than
one year ago). OsmoBSC has already been making use of it since then (see
osmo-bsc.git 8d22e6870637ed6d392a8a77aeaebc51b23a8a50); lets use this
feature in osmo-hngw too.
This commit is also part of a series of patches cleaning up
libosmo-mgcp-client and slowly getting rid of the old non-mgw-pooled VTY
configuration, in order to keep only 1 way to configure
libosmo-mgcp-client through VTY.

The spec permits RAB AssignmentRequests with multiple RABs at a time.
Even though one voice call is assigned only one RAB in practice. Since
the current FSM implementation only supports a 1:1 scenario, lets check
if the MSC really assigns only one RAB and block RAB Assignments that do
not fit in this scheme.
