Made the following changes:

- Use host name specified in ObtainAuthToken call instead of the
    normalized host name to connect to the ATS to avoid problems
    when the host name obtained through a reverse DNS lookup fails
    to resolve via a forward DNS lookup.

  - Added the capability log debug messages to a file.

  - Added method to the ConfigIf to free memory returned by calls to
    getEntryValue to avoid issues related to freeing memory allocated
    with a heap different than the one owned by the library freeing
    the memory.
