Move the definition of the NotifyItem and NotifyList types from struct.h to notify.h

This change means that struct.h no longer needs to include alist.h, so it will be indirectly included in a lot
fewer other files.

As a consequence, server.h needs to include notify.h to get the definitions of those data types.
