Pass the guest ASCE explicitly as parameter, instead of having sie64a()
take it from lowcore.
This removes hidden state from lowcore, and makes things look cleaner.

Move and improve the struct definitions for DAT tables from gaccess.c
to a new header.
Once in a separate header, the structs become available everywhere. One
possible usecase is to merge them in the s390 pte_t and p?d_t
definitions, which is left as an exercise for the reader.
