Previously, each try to open the file using a different PFN would report an open attempt for the same LFN. This meant we could have multiple opens but only one close for a given LFN.

When sending information to the StatisticsSenderService, the file LFN or URL must be supplied.

Send statistics for primary, secondary, and embedded files.
The aggregate file statistics are only reset on primary file close boundaries to keep the behavior the same as previous.
Changed all calls to closeFile_() to be the new closeFile()

Now broadcasts how the file is used.
