Osmocom has maintained this program since about 7 years now, while
the original author / copyright holder has completely disappeared.
With the introduction of Osmocom-style CTRL and VTY interfaces,
the way how the program is used and configured has substantially
changed. In order to avoid confusion in terms of configuration file
format etc, let's rename it to OsmoGGSN.

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.
