Let's use the preprocessor to avoid IPA_Emulation pulling *all*
dependencies into each and any of our projects. The code readability
suffers a bit from the many #ifdefs, but compilation speed increases
if we don't have to pull in all those (recursive) dependencies.
After all, a BTS test case will never need SCCP, GSUP or MGCP.

Based on the exsting NS/BSSGP emulation as well as the VTY, GSUP and
CTRL implementations, we are now building a test framework skeleton
for osmo-sgsn.
