AVX2 brings the new PMOVZXBW instruction that extends from one 128-bit
SSE register to an 256-bit AVX register. With that, the main decoding
code is just two instructions (the loop requires a couple more to
maintain the offset counter and do the end-of-loop check).
This buys us another 4% performance improvement in the fromLatin1 code,
calculated on top of the VEX-encoded SSE2 code (which is already a little
better than plain SSE2).

It's a common need to assign a variable to something when entering a
code block, and then revert it upon exit. qscopedvaluerollback can
be used for this. But as a convenience, this patch adds an
extra constructor so that you can "protect" and set a variable
in one go instead of using two lines.

formats() -> formatCollection()
additionalFormats -> formats
QTextEngine has three different code paths: in context of QTextDocument,
additionalFormats are currently _additional_ formats;
though in QTextLayout, they are the only formats in use;
and the QRawFont-related path shares the QTextLayout's behavior.
This is a preparation step to consolidating these three into a single one.

First and foremost, the STL-style iterators don't do this. Those don't
provide a guarantee that the container won't get shared again while the
iterator is active.
Second, there's no protection against a second mutable iterator being
created and resetting the sharable flag back to true.
[ChangeLog][Important behavior changes] The mutable Java-style iterators
like QListMutableIterator and QHashMutableIterator no longer set the
parent container to unsharable mode. If you create a copy of the
container being iterated on after the iterator, any changes done with
the iterator might affect the copy too.

It had no effect because of an explicit check for NoBrush.
However the default in QBitmap is (unfortunately) QBrush(color0), rather
than NoBrush, so the brush must be updated when calling setBrush(NoBrush).
I suppose the real issue is that lastBrush is default-constructed in
QRasterPaintEngine, rather than starting with the brush from QPainter,
which is QBrush(color0) for the case of the bitmap. But no reason to
special case NoBrush here anyway.

For webfonts, we can't rely on the fontDef (and hence the cache Key) alone,
since the resulting fontcache key might be strictly identical.
Instead we have to check if the cached engine doesn't belong to a webfont

Up to now, Qt had at least 3 different implementations of the mid().
Only QString::mid implementation was not crashing on edge cases and
was protected against overflows, therefore I picked that one as the
base implementation, even if it has weird semantics for an invalid
input.
As a side effect QVector::mid was slightly optimized to not detach in
all cases (which follows current QList behavior). Documentation of
QVector::mid and QList::mid was updated to not mention "copy of data"
which could suggest that the mid() result is detached.
QStringRef::mid was fixed and now it follows general Qt behavior, by
returning a null value for a null input.
