bitbake/cooker, bitbake-layers: show the .bbappend files that matches no existing .bb recipe

This patch moves the logic of show_appends_with_no_recipes from bitbake-layers
into bitbake. By default, a fatal message is printed; we can also define a variable
BB_DANGLINGAPPENDS_WARNONLY to make the message only a warning(the variables
could be defined in conf/local.conf with a value "yes", "true" or "1").
