+  Compare two items using a given collation
+  
+  SYNOPSIS
+    eq_by_collation()
+    item               item to compare with
+    binary_cmp         TRUE <-> compare as binaries
+    cs                 collation to use when comparing strings
+
+  DESCRIPTION
+    This method works exactly as Item::eq if the collation cs coincides with
+    the collation of the compared objects. Otherwise, first the collations that
+    differ from cs are replaced for cs and then the items are compared by
+    Item::eq. After the comparison the original collations of items are
+    restored.
+
+  RETURN
+    1    compared items has been detected as equal   
+    0    otherwise
