    MINOR: lua: export applet and task handlers
    
    The current functions are seen outside from the debugging code and are
    convenient to export so that we can improve the thread dump output :
    
      void hlua_applet_tcp_fct(struct appctx *ctx);
      void hlua_applet_http_fct(struct appctx *ctx);
      struct task *hlua_process_task(struct task *task, void *context, unsigned short state);
    
    Of course they are only available when USE_LUA is defined.
    
    (cherry picked from commit 60409db0b1743d670e54244425f6e08c389b7dde)
    [wt: backported to improve troubleshooting when the watchdog fires;
         while in 2.0 we also have hlua_applet_htx_fct(), it's not
         visible outside hlua_applet_http_fct() so we don't care]
