MEDIUM: stconn: Explicitly pass shut modes to shut applet endpoints

Browse Source 
It is the same than the previous patch but for applets. Here there is
already only one function. But with this patch, appctx_shut() function was
modified to explicitly get shutdown mode as parameter. In addition
appctx_shutw() was removed.
