When a peer GSN receives a GPDU for an unknown PDP context, it sends
a GTP Error Indication. This Error Indication should be used to
delete the offending PDP context locally.
In GTPv1, the Error Indication contains some mandatory IEs using
which we can look up the PDP context and delete it.
The existing code only dealt with GTPv0 Error Indications which lack
those IEs and use the TEI in the header instead.

Closes: OS#2426
After so many years of silence, we don't expect the original author to
return to the project. To make things a bit simpler for us, we convert
the coding style to what we are used to (Linux style).
The conversion was made using the 'Lindent' script which is part of the
Linux kernel.

This adds support for the followng new GTP Information Elements:
RAT_TYPE, USER_LOC, MS_TZ, IMEI_SV
Furthermore, it allows to specify those fields as sgsnemu command line
arguments.
