server-tools/instance-manager/IMService.cpp:
  make sure HandleServiceOptions returns 0 on success and 1 on failure
server-tools/instance-manager/mysqlmanager.cc:
  default return value is 1.
  simplify some code bits by just jumping to err on error.
  move options.cleanup inside the err block.  In this case, the err block
  is more than just an error block.  It is the terminating block
  for both error and success.  You set return_value to 0 for success
  or leave it as 1 for failure.  This simplies this function a bit.
server-tools/instance-manager/options.cc:
  remove the malloc for default password filename on Windows and replace
  with statically allocated memory.
  
  default Options:saved_argv to NULL so that we will know if we need
  to free it in cleanup()
  
  setup the default config file location for Windows inside the
  setup_windows_defaults function and remove this code from load()
  
  rework setup_windows_defaults so that it properly returns 0 on success
  and 1 on error and so it fills in the default location for the
  log file, password file, and config file.
