      Bug #57274 SET GLOBAL debug crashes on Solaris in embedded server mode
      
      The problem was that "SET GLOBAL debug" could cause a crash on Solaris.
      The crash happened if the server failed to open the trace file given in 
      the "SET GLOBAL debug" statement. This caused an error message to be
      printed to stderr containing the process name. However, printing to
      stderr crashed the server since the pointer to the process name had
      not been initialized.
      
      This patch fixes the problem by initializing the process name 
      properly when doing "SET GLOBAL debug".
      
      No test case added as this bug was repeatable with existing test
      coverage in variables_debug.test.
