[tmsi] Make the tmsi a 4 octet number

tmsi is four octets long, there is no need to make it a string
and then jump through hoops to convert it to a number. Keep the database
using it as a string to benefit from the NULL handling of the db.

Introduce the reserved tmsi which has all bits set to 1 according
to GSM 03.03 §2.4 and start checking for it and make sure the db
code will never allocate such a tmsi.
