Some clarifications / notes:

This also includes changes to some of the ifoRead_* functions as well.

The reason things are set to NULL either on closing some of the
functions is because both ifo_Read_* and ifo_Free_* functions will work
on partial amounts of data that is already populated.  Meaning, it's
important to always clean up after itself so that the other reads /
writes don't screw up.

Next in line is to cleanup all the Read functions, but for now it just
reassigns pointers to NULL.
