We don't need a getter for the 'preset' of a color-space, as color
spaces can be compared to the presets directly. This allows us to
remove the Undefined and Unknown values from the presets.
Internally we still distinguish known presets from unknown or undefined
presets via the magic 0-value. The validity of a QColorSpace is not
based on this preset, but on its actual values.

QImage comparison has always ignored differences in
metadata. Introducing colorspace comparison can break backwards
compatibility, as not all image formats or handlers have colorspace
capability.
This partially reverts commit
733ca2230c283cdfaae424eac481ddc33593f44f.

- Unexport the value class, export only out-of-line public member functions
to give us more leeway in changing code later (otherwise, we'd be bound
by BC with MSVC debug builds, which call even inline methods from the DLL.
- Don't use QSharedPointer as the d_ptr. It's twice the size of a pointer.
Use a naked pointer-to-const. Derive Private from QSharedData. This
requires some changes in QColorSpace, and, as usual, an out-of-line copy
ctor.
- Add member-swap(), Q_DECLARE_SHARED().
- Drop noexcept from the dtor. It implicitly is, adding it explicitly looks
weird.
- Pass QRgb and QRgba64 by value, not by cref. They're trivially-copyable,
so passed in registers if passed by value. Passing by cref forces them
onto the stack.

Semi-automated, just needed ~20 manual fixes:
$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)load\(\)/$1loadRelaxed\(\)/g' -i \{\} +
$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} +
It can be easily improved (e.g. for store check that there are no commas
after the opening parens). The most common offender is QLibrary::load,
and some code using std::atomic directly.

QImage's operator>>(QDataStream&) did not set an error mode on the
stream on read failures. That would break QDataStream transactions.
Since the current QImage serialization cannot differentiate between
truncated and corrupted data, we set the ReadPastEnd error as expected
by the transaction system.
Also specify the expected file format on decoding QImage from stream,
to avoid all the format handlers' canRead() being invoked. This is
necessary since some of them may call ungetChar(), which fails when
the stream is in a transaction.
Also add testing of this feature to the QDataStram transaction
autotest. That required a slight rewrite of the fake sequential
QIODevice subclass. The previous implementation had incorrect
behavior of peek(), which is required by QImage decoders.

The simple scaling that only samples every input pixel once, can be
used with downscaling < 2x as well if we just handle the case where the
input can't be in the intermediate buffer.
At the same time the handling of the intermediate buffer has been moved

AVX2 optimizations also used for non-argb32pm formats.
