FIELD_ARRAY: safely handle 0-sized fields #41

This PR adds a check so that FIELD_ARRAY does not wrap 0-sized fields. It also adds the P_FIELD pointer member which we need for our Loki recipes to move from thread-local to shared data structures. Finally, there is a small bug fix to the fypp detection mechanism.

Good you thought about zero-sized arrays.
