Rename BSSMAP_Emulation -> RAN_Emulation

So far, BSSMAP_Emulation supported only a transport over BSSMAP.
However, we soon intend to merge support for RANAP in order to
simulate RANAP/Iu connections as well as BSSMAP.  Let's start
by renaming some of the existing types/functions/ports/modules
without introducing any functional changes just yet.
