changing it to use it. There was an extra parameter added to the static accessor global user settings controllers that wasn't needed. A bool was being used as a parameter to the accessor just so it could be used to clean up the global user settings controller which is now fixed by splitting up the initialization into the "static void Class::Initialize()", access into the "static UserSettingsControllerSP & Class::GetSettingsController()", and cleanup into "static void Class::Terminate()". Also added initialize and terminate calls to the logging code to avoid issues when LLDB is shutting down. There were cases after the logging was switched over to use shared pointers where we could crash if the global destructor chain was being run and it causes the log to be destroyed and any any logging occurred. llvm-svn: 119757
