Fix resp_calls array size

Browse Source 
This got broken during a refactoring in de71282922. We need the plus 2
items because of the overflow/underflow bucket, without that we can
possibly overindex this array and corrupt other counters.

In earlier versions we even had the encoding variable stored directly
after this array, which possibly caused crashes or incorrectly working
string functions.
