Lars Knoll 3a48320fd6 Fix performance regression when appending one vector to another 
When appending a QVector to an existing vector the code would
unconditionally realloc the vector instead of first checking
whether we can do without. This gives a quadratic behaviour when
repeatedly appending a vector to another.
