Implement RingQueue::resize()

[gavv]

Add resize() method to core::RingQueue (fifo on top of ring buffer).

Example of similar method can be found in core::Array. Note how it invokes constructors and destructors of the elements.

We also need to add tests for resizing to test_ring_queue.cpp.

Pull request merged.

Here is the comment for resize():

    //! Change ring queue capacity.
    //! @remarks
    //!  After this call, capacity() is equal to the new value, and size()
    //!  is either the same as before or smaller if capacity decreased.
    //!  When needed, performs reallocation or destroys excess elements in
    //!  the end of the queue.
    //! @returns
    //!  false if the allocation failed
