especially important for HFS+, which will store file names in decomposed

Saving strings with embedded zero-bytes (\0) as CFStrings would
sometimes fail, and only write the part of the string leading
up to the first zero-byte, instead of all the way to the final
zero-terminator. This bug was revealed by the code-path that
falls back to storing e.g. QTime as strings, via the helper
method QSettingsPrivate::variantToString().
We now use the same approach as on platforms such as Windows
and WinRT, where the string produced by variantToString() is
checked for null-bytes, and if so, stored using a binary
representation instead of as a string. For our case that
means we fall back to CFData when detecting the null-byte.
To separate strings from regular byte arrays, new logic has
been added to variantToString() that wraps the null-byte
strings in @String(). That way we can implement a fast-path
when converting back from CFData, that doesn't go via the
slow and lossy conversion via UTF8, and the resulting QVariant
will be of type QVariant::ByteArray. The reason for using
UTF-8 as the binary representation of the string is that
in the case of storing a QByteArray("@foo") we need to
still be able to convert it back to the same byte array,
which doesn't work if the on-disk format is UTF-16.

We can't forward a VerticalSortHint or HorizontalSortHint hint, because we might
be filtering extra items.
The documentation of QAbstractItemModel::LayoutChangeHint states:
Note that VerticalSortHint and HorizontalSortHint carry the meaning that
items are being moved within the same parent, not moved to a different
parent in the model, and not filtered out or in.
And some of the views rely on this assumption (QQmlDelegateModel for example)
What happens in the test is the following:
- 'model' emit the dataChanged signal when its data is changed.
- 'proxi1' QSortFilterProxyModelPrivate::_q_sourceDataChanged does not forward
the dataChanged signal imediatly, it will instead first re-sort the model and
call layoutAboutToBeChanged / layouChanged with the VerticalSortHint
- 'proxy2' would forward the layoutAboutToBeChanged with the hint, but in
QSortFilterProxyModelPrivate::_q_sourceLayoutChanged, it will redo the mapping
which will cause the changed data to be filtered.
So proxy2 can't forward the VerticalSortHint as it removed rows in the process.

This caused failures on Windows (which uses "System"/Latin1 encoding)

altogether and also enables the use of larger character spaces for the
pattern.

When replacing each copy of one text with a copy of another, we do so
in batches of 1024; if we get more than one batch, we need to keep a
copy of the sought text and replacement if they're part of the string
we're modifying, for use in later batches.
Also do the replacements in full batches of 1024, not 1023 (which left
the last entry in an array unused); marked some related tests as
(un)likely; and move some repeated code out into a pair of little
local functions to save duplcation.
Those new functions can also serve replace_helper(); and it can shed a
const_cast and some conditioning of free() by using them the same way
replace() now does. (There was also one place it still used the raw
after, rather than the replacement copy; which could have produced
errors if memcpy were to exercise its right to assume no overlap in
arrays. This error is what prompted me to notice all of the above.)
Added tests. The last error proved untestable as my memcpy is in fact
as fussy as memmove. The first two tests added were attempts to get a
failure out of it. The third did get a failure, but also tripped over
the problem in replace() itself. Added to an existing test function
and renamed it to generally cover extra tests for replace.

Serialization of the Qt container classes is accomplished by breaking
up the data into primitive units. On the receiver side, these units
should be read atomically to guarantee integrity of the container.
Deserialization procedures for QHash and QMap were already implemented
in accordance with this strategy and have the following behavior:
- a previously latched error status is saved for the caller. This
overrides possible different errors in the current read. This
is consistent with the treatment of primitive types.
- if an error occurs during the deserialization, the container is
cleared.
To make the API consistent, this patch adjusts the behavior of QList,
QLinkedList, QVector, and QSet deserialization. On the implementation
side we accomplish this with a private StreamStateSaver RAII class that
consolidates the handling of the stream status for all containers.
[ChangeLog][Important Behavior Changes][QtCore][QDataStream] Incomplete
reads of Qt containers are now handled same way as for primitive types,
meaning that previous errors are latched.
