  Initialize all MySQL global variables to default values

  SYNOPSIS
    mysql_init_variables()

  NOTES
    The reason to set a lot of global variables to zero is to allow one to
    restart the embedded server with a clean environment
    It's also needed on some exotic platforms where global variables are
    not set to 0 when a program starts.
