Move the "finding" of the right BTS into paging.c
Move the secret of how to find the BTS in a LocationArea into
the paging layer. This allows to implement different strategies
without changing other parts. E.g. we might want to try the BTS
were the device was seen last and then try...
There should be no semantic change and things should continue
to work. It is sadly not tested though.
