libmsc: add timer X36 for delaying LU connections
The idea is to allow re-using the radio channel that was used for
Location Updating to deliver MT SMS over GSUP. This is achieved
by delaying release of a BSSAP/RANAP connection and thus delaying
the release of the radio channel. The delay can be configured
using new timer X36 (default 0 ms), separately for GERAN and UTRAN.
