Revert "saldllapi.h is really not included outside of sal itself"

This reverts commit 2dfe34ce:

* sal/saldllapi.h is about something different than sal/types.h (it is rather a
  mistake of cf77e8a0 "sal: add visibility
  symbols" to shortcut the #include of sal/saldllapi.h into sal/types.h instead
  of the headers that actually need it), not every header needs to include
  sal/types.h

* sal/config.h is the header to always include first (not sal/types.h)
