Attempt to introduce guard against tap out of bounds access

Not 100% sure if this is what you guys are looking for. 

If necessary just provide an example based on one of the current message, like
for example handle_ButtonTemplateMessage.

Question1: Where should i add the "if (ptvcursor_tree(cursor) != NULL)" check ?
Question2: currently we are using:
ptvcursor_add_text_with_subtree(cursor, SUBTREE_UNDEFINED_LENGTH,....
Maybe we should change that to:
ptvcursor_add_text_with_subtree(cursor, (capCount *
capabilitiesStructSize),....
Would that help as well ?
