BUG#: 2297
TITLE: Need to Fix Pegasus Typedefs
DESCRIPTION: Conditionally compile char Array instantiation with PEGASUS_USE_DEPRECATED_INTERFACES flag.  Add PEGASUS_REMOVE_DEPRECATED_INTERFACES flag in config.mak to allow deprecated interfaces to be compiled out in Pegasus builds.  Update CIMValue doc++ to clearly mark the deprecated interfaces.
