There are some leftover global functions in the code that are not referenced at all anymore. These functions are removed by this patch. There are also some global functions that are only used in their own modules. These functions are made static by this patch. JerryScript-DCO-1.0-Signed-off-by: Akos Kiss akiss@inf.u-szeged.hu
