Added QAbstractVideoBuffer::release virtual method
It's useful when the buffer pool stores QAbstractVideoBuffer
instances instead of underlying system buffers and
allows to avoid reallocation of QAbstractVideoBuffer instances.
The default implementation deletes the buffer,
so this change is source compatible.
