Add support for CSS3 overflow-x and overflow-y properties.

  Now, overflow is a shorthand property setting both overflow-x and
  overflow-y.

  The getter for the computed overflow has been removed, and replaced
  with two for overflow-x and overflow-y.

+-----------------------------
+
+  The API is changed.
+
+  Due to the change from CSS2 overflow to CSS3 overflow properties, the
+  computed style access functions for overflow properties have changed.
+  The overflow property is removed.  Added are overflow-x and overflow-y
+  properties.  (The overflow shorthand property now sets overflow-x and
+  overflow-y.)
+
+  This change affects the following functions:
+
+    Removed from   include/libcss/computed.h    --  css_computed_overflow()
+
+    Added to       include/libcss/computed.h    --  css_computed_overflow_x()
+
+    Added to       include/libcss/computed.h    --  css_computed_overflow_y()
