Since its initial implementation, QRingBuffer had the following
fragilities in the architecture:
- it does not guarantee validity of the pointers, if new data will
be appended. As an example, passing an address of the QRingBuffer
chunk as a parameter to the WriteFileEx() function on Windows
requires the stability of the pointer. So, we can't add new data
to the QRingBuffer until the overlapped operation completed
(related issues were fixed for QWindowsPipeWriter and QSerialPort
in 5.6 branch by introducing an intermediate byte array);
- inefficient reallocations in reserve(), if a shared chunk was
inserted in the queue (we can get a reallocation in the place
where we don't expect it:
char *writePtr = buffers.last().data() + tail; <- line #133
).
Proposed solution is to avoid reallocation by allocating a new
block instead. That was accomplished by introducing a QRingChunk
class which operates on a fixed byte array and implements head/tail
pointers strategy for each individual buffer in the queue. So,
QRingBuffer is no longer dependent on QByteArray's internal
shrink/growth algorithms.

Like in commit 75cdf654bc, we use the

end() directly; in here, it happens when iterating forward from any

However, using static_cast is wrong, so we use reinterpret_cast.

rowsMoved are used for this (8021e2d5e7).
With this change, QAbstractItemViewPrivate::_q_rows/columnsMoved() is
calling the virtual function _q_layoutChanged(). This resulted in a
wrong call of QHP::_q_layoutChanged() for a horizontal header when
a row changed and for a vertical header during a column change. In the
end this can lead to an unhide of hidden sections.
