Instead of listing each and every context map, rather output a summary of
context counts.
Rationale: in a list of a hundred HNBs, I don't want to also see a dozen (or
potentially thousands of) context map lines for each. Furthermore, the conn IDs
aren't necessarily useful on network traces either.
For example, what was shown as SUA Id is incidentally the SCCP Reference, but
this is not a hard requirement and may change. Also, the reference is shown in
wireshark as a hex in mismatching byte order ... so rather don't bother.
The result now looks like
OsmoHNBGW> show hnb all
HNB (r=192.168.0.124:29169<->l=192.168.0.9:29169) "000295-0000152614@ap.ipaccess.com"

In the vty config, use the SCCP address book to configure the local and remote
SCCP addresses. Add VTY commands to set the remote SCCP addresses by name,
derive the ss7 instance from these addresses:
cs7 instance 1
point-code 0.23.0
sccp-address msc
point-code 0.0.1
sccp-address sgsn
point-code 0.0.2
hnbgw
iucs
remote-addr msc
iups
remote-addr sgsn
Enforce that both IuCS and IuPS use the same ss7 instance. In the future, we
may add the feature to use two separate instances.

Basically copy-paste the Iuh local-ip and local-port code to provide
parameterization of the IuCS and IuPS remote addresses.
Add IUCS and IUPS nodes, enhance go_parent_cb and config writing accordingly.

A second level of depth will be added to the hnbgw node soon, which will need
explicit go-parent logic.

For completeness' sake, add VTY command to set the local Iuh port, to go with
the command that sets the local IP.

Prepare for parameterization of IuCS and IuPS addresses:
Conform internal variable naming to local-ip, local-port, remote-ip,
remote-port (instead of bind-ip).
Rename HNBGW_IUH_LOCAL_IP_DEFAULT to HNGGW_LOCAL_IP_DEFAULT to be more general
and move it to the top.
Move a function doc comment to the .c file.

The standard osmo VTY terminology is 'remote-ip', 'remote-port', 'local-ip',
'local-port'. Conform to that. osmo-hnbgw is so far not rolled out widely, so
it makes sense to do this now.

Add the option to allow UE Register Requests with a TMSI identity.
Add VTY command to enable this option, 'hnbap-allow-tmsi'.
Add hnbgw_tx_ue_register_acc_tmsi().
HNBGW so far keeps track of UEs that have registered, with their IMSI. When a
UE registers with only a TMSI, we obviously can't store an IMSI. However, since
we're so far never *using* the list of UEs in osmo-hnbgw, we might as well just
accept the TMSI registration and carry on as usual. All that is needed for
proper operation is a valid UE context.
This is aimed at the ip.access nano3G femto cell, as it apparently feeds
whichever identification the UE sends through to HNBAP (TMSI+LAI, pTMSI+RAI),
instead of an IMSI as expected. So far this caused failures and the need to
make the UE clear its TMSI (wait several minutes or attempt to subscribe to a
different network), so that UE registration switched back to IMSI. When simply
accepting the TMSI in osmo-hngw, no problems are apparent in our current code
state.
For example, a Samsung Galaxy S4 seems to send a UE_Identity_PR_tMSILAI (CS
identity), and a GT-I9100 seems to send a UE_Identity_PR_pTMSIRAI (PS identity)
upon first registration to the network.
Recording the IMSI in hnbgw: we could use the subscriber list during paging, to
page a UE on only its last seen HNB. On the other hand, it doesn't hurt to
anyway always page to all HNBs connected to osmo-hnbgw. The paging procedure
does include a page-to-all-HNBs in case the first HNB paging fails. But we must
be aware that UEs that register by TMSI will simply not have an IMSI recorded
in the list of UE contexts, so a lookup based on IMSI may fail.

This came up while fixing 'make distcheck'; this is certainly not the easiest
way but it makes sense to have the headers in include/, like we do in openbsc.
The easy alternative might be to add -I$(top_srcdir)/src to src/Makefile.am.
Remove -I$(top_srcdir)/src from src/tests/Makefile.am, no longer needed.

Add config node hnbgw/iuh/bind, taking an IPv4 address.
Use this address to bind the Iuh server.
This is particularly useful for the ip.access nano3G, which is very sensitive
with SCTP addresses that don't respond to SCTP heartbeats. If the hnbgw listens
on 0.0.0.0, there will be SCTP heartbeats for all local interfaces on the
machine that the hnbgw runs on; the nano3G will interpret the "missing", or
rather, redundant heartbeat acks for the interfaces that aren't really related
to the Iuh server and assume a broken Iuh link, leading to an Iuh shutdown and
reconnection, looping every minute or so. By binding the hnbgw to only one
local interface, the SCTP addresses can be reduced and "missing" heartbeat acks
can be avoided.

Add include/osmocom/iuh/ named after this project (osmo-iuh), and add vty.h to
define VTY node enum values. Also add (to) Makefile.am and configure.ac to
include in the build.
An upcoming commit will add the actual first config item to the hnbgw/iuh node.
