API changes:
- hb_shape() and related APIs now abort if buffer direction is
HB_DIRECTION_INVALID. Previously, hb_shape() was calling
hb_buffer_guess_segment_properties() on the buffer before
shaping. The heuristics in that function are fragile. If the
user really wants the old behvaior, they can call that function
right before calling hb_shape() to get the old behavior.
- hb_blob_create_sub_blob() always creates sub-blob with
HB_MEMORY_MODE_READONLY. See comments for the reason.
