Data in item models is most often organized in rows, where each column
contains an attribute of the item represented by the row. Often when
sibling is used, it is to request another piece of data from the same
row. Having a specialized version makes this easier and less awkward
to do, simplifying
auto sibling = index.sibling(index.row(), columnOfInterest);
to
auto sibling = index.siblingAtColumn(columnOfInterest);
For symmetry reasons, siblingAtRow(rowOfInterest) was also added.

When implementing a custom model there's the habit, in each and every
function that takes a QModelIndex, to carefully checking the index
passed by the caller. This index is checked for "legality" (*): does the
index belong to this model, is the index pointing to an existing row and
column, and so on. These checks are hand-rolled and, as such, slightly
different and possibly incomplete (i.e. wrong) every time.
What's worse, these checks are implemented via "ordinary" code (if
statements). However, passing an illegal index to a QAIM function is a
precondition violation, and as such does not (and must not) be
checked in ordinary conditions, as it triggers undefined behavior. On
the other hand, while debugging a custom model or a custom hierarchy
of (proxy) models, having such checks in place can be a significant
aid.
Enter checkIndex(): a debugging helper for QAbstractItemModel and its
subclasses. checkIndex() centralizes the checks for legality of a
given index. User code is free to assert on it, or have some other
fallback mechanism in case a check fails.
(*) Using "legality" here instead of "validity" in order to avoid
confusion between QModelIndex::isValid() and what checkIndex() really
does.
[ChangeLog][QtCore][QAbstractItemModel] Added
QAbstractItemModel::checkIndex(), a debugging function for
QAbstractItemModel subclasses.

Make sure we properly handle both directional embeddings as well as
directional isolates to determine the direction of the string.
According to the latest version of the Unicode bidi algorithm,
parts of the string contained inside an directional isolate is
to be ignored when determining the paragraph direction. Embedding
markers themselves are to be ignored as well, but not the characters
inside an explicit directional embedding or override.
This is also some required pre-work to get our BiDi algorithm

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.

Commit 68bcccac took account of MS TZ APIs mis-describing non-DST
zones making changes to standard offset (e.g. Europe/Samara in 2011 at
the end of October); however a DST transition that coincides with an
equal and opposite change to standard offset, while the other end of
its DST period changes normally, ends up looking exactly the same
(although it's nominally subtly different), in MS's APIs. Thus fixing
the more common case broke this more obscure case; there is no way to
fix this (other than not using MS's broken-by-design APIs). So kludge
the test to skip the bit we know this breaks.

Previously, we would use mime.cache in all mime directories if at
least one of them had such a file (other than the most-local one),
otherwise the "source" XML would be used in all directories.
Now it's possible to use mime.cache in those directories which
have one, and XML in those directories that don't.
Not only is this more correct, it will allow in a subsequent
commit to bundle the binary cache in QtCore's qrc rather than
the very big XML file.
The design change to allow this is that now every provider
only deals with a single directory, and QMimeDatabasePrivate
takes care of creating multiple providers, one for each dir.
This required to move most of the loops from the binary provider
up to QMimeDatabasePrivate itself.
