Return the size of object o. If the object, o, provides
both sequence and mapping protocols, the sequence size is
returned. On error, -1 is returned. If the object provides
a _length_cue() method, its value is returned. This is the
equivalent to the Python expression:
try:
return len(o)

if hasattr(o, '_length_cue'):
return o._length_cue()
