 Convert the MythSystemPrivate classes to use RefCounters

 We were getting some odd race conditions caused by the timing of deletion
 of
 the MythSystemPrivate data (MythSystemUnix in particular on Linux and
 OSX).
 As we now have a common ReferenceCounter class to use, I have converted
 this
 over to use ReferenceCounter to control the deletion.  One reference is
 made
 on creation, and a second when it is added to the process map.  The second
 reference is decremented when the MythSystemSignalThread is done shutting
 it
 down cleanly.

 NOTE:  I may have missed some dependency on the parent item which may have
 been deleted already.  If this happens, please let me know.  It would most
 likely crash hard in this case.  I'll take another look over it in a bit.
