src: add flag to add event wrapping in output functions
This patch uses the flag option of each output function to print an
event wrapper string in each object.
In order to use this functionality, the caller must pass the
corresponding flags: NFT_OF_EVENT_NEW / NFT_OF_EVENT_DEL.
(I have slightly refactorized the original code to add the xml/json
header and footer --pablo).
