BUG/MEDIUM: pattern: fix wrong definition of the pat_prune_fcts array
Commit 6f7203d ("MEDIUM: pattern: add prune function") introduced an
array of functions pat_prune_fcts[] but unfortunately declared it in
pattern.h without marking it "extern", resulting in each file including
it having its own copy.
