I think we could use the random() / srandom() functions, which are standard
POSIX API. We could seed it with something like the time it takes us to
receive the first location update request after boot, or something unpredictable
like that.
In the end, we have at least three parts in our system that need a 32bit random
value: The TMSI, P-TMSI and the RTP source ID
