support osmo-sip-connector with kamailio

Kamailio is a SIP server, that is relatively easy to configure, in
contrary to asterisk it only has one config file. The config file
here is based on the example config provided in the wiki:



To enable the osmo-sip-connector, build it, install kamailio and
then set SIPCON_ENABLE=true in your copy of config_2g_3g.

Done. Both use ${NET_DIR} now which is introduced here:

Patch Set 7:

So far, all of the osmo-dev/net happens within that subdir, and I want to keep 
it that way if possible. I would also have commented similarly on the socket 
path, but that's a user config item. Maybe also make that rundir a user config 
item, then I can't really complain anymore.

But even nicer would be to just place both socket and rundir in the same dir 
where the run.sh sits by default. No need to configure.

If it's too much effort we can merge this now, but I guess it's simple enough?

Turns out, it is configurable as "rundir" in the config. I've set it to 
"/tmp/kamailio_rundir" now, and kamailio creates that folder and is happy with 
it.

It would of course be better to not use /tmp for this either (or to have random 
names and clean it up properly). But then again we would need to change that 
for the socket path too, so I think it is good enough for now.

Maybe at a later point we could add a well defined temporary directory to the 
script, which can be used with a variable in the configs.

Your thoughts on sudo sound good to me.

can we instead keep the kamailio run dir as a local subdir? Is it not 
configurable in kamailio.cfg?

Above sudo is intended only for configuring the network, all the remaining 
stuff should be userland and shouldn't modify the current root system.

Hmm, I think we should even remove sudo from the tcpdumps, possibly skip 
tcpdump if the user has no setuid on dumpcap; and maybe even separate all 
network config sudo stuff to a separate script... (what was I thinking!)

File net/config_2g3g:

https://gerrit.osmocom.org/#/c/11144/1/net/config_2g3g@33
PS1, Line 33: MSC_MNCC_SOCKET="/tmp/bsc_mncc"
Minor nitpick: change to /tmp/msc_mncc

The old name is from the days where we had openbsc instead of osmo-msc so it's 
somewhat misleading now.

Good point, changed to "=".

PS1, Line 68:   kamailio="$(sudo which kamailio)"

yes. I could also set PATH=... beforehand if that is more elegant.
