### Description
During some test on my server I forgot to configure a valid listen network address.
It's my fault but Kamailio crashed with a useless message:
kamailio[4739]: segfault at 0 ip 00007f022ede5e71 sp
00007fff94033f08 error 4 in libc-2.17.so[7f022ec82000+1b6000
I think it's better to abort the startup if no listen address is specified and with an
explicit error message, instead of produce a segfault and a crash without any error

Likely this is due to a module cleaning up some uninitialized structure, because kamailio
should deal nicely when the listen address cannot be found.
To see where the issue resides, it is good to have a core dump and get the backtrace. Be
sure you set `ulimit -c ulimited` in terminal and start kamailio as root. Once you get the
core file, grab the backtrace with gdb and paste it here. If you installed from packages,
then you may need to install debug info package in order to get useful backtrace.

What version of kamailio are you using? The code seems to be safe there.
I also tried to reproduce by having a listen with a non local ip and it didn't crash,
it prints the error message and exits:
```
ERROR: <core> [core/udp_server.c:397]: udp_init(): bind(6, 0x10c606504, 16) on
192.168.178.188: Can't assign requested address
```

version: kamailio 5.0.1 (x86_64/linux)
Tip to reproduce: enable TLS but do not define any "listen=" addresses

this is the good functionality of kamailio if no listen is mentioned then kamailio listen
to local interface.
But as you are not getting proper log. we will try to reproduce it and if we found the
issue then we will print the error log on this.so you can identify what things are wrong
with config.

I was not able to reproduce. I did a fresh install and started with default `kamailio.cfg`
that has `WITH_TLS` defined. All started fine, the `kamctl srv sockets` shows that
`kamailio` is listening on tls.

If there are no other details that you can provide, like all log messages with debug=3 in
kamailio.cfg or output of `bt full`, I am closing this one in the near future, being not
able to reproduce it here.

kamailio will just crash

@nshopik - yours looks more like #1189. Open a new bug if that doesn't apply and
attach all the information as requested by the bug issue template. This one is going to be
closed, not able to reproduce.
