tx: add functions for logging

Add function AppLayerParserRegisterLoggerFuncs for registering
a callback function for checking if a specific logger has logged
a transaction, and a callback function for specifying that it has.

Also add functions AppLayerParserGetTxLogged and
AppLayerParserSetTxLogged to invoke these callback functions.
