It identifies the new generic package added in s-shasto.

* s-shasto.adb, s-shasto.ads: A new generic package has been added, it
is instantiated for each shared passive variable. It provides
supporting procedures called upon each read or write access by the
expanded code.

* sem_attr.adb:
For this runtime unit (always compiled in GNAT mode), we allow
stream attributes references for limited types for the case where
shared passive objects are implemented using stream attributes,
which is the default in GNAT's persistent storage implementation.
