get rid of those classes for Qt 6.

That allows us to pass by value for all fundamental and pointer types.
This requires some magic to remove methods taking a T&& to avoid
ambiguous overloads for QVector<int/qsizetype>. Remove them for all
cases where parameter_type is T, as copying or moving will do
exactly the same thing for those types.

Don't store our string data as QByteArrayLiterals anymore, but revert
back to simply storing them as an array of char* and offsets into that
array.
This is required to be able to inline size and begin into QByteArray
itself. Once that change is done, we can then avoid creating copies of
the string data again.

I'd have preferred to use QArrayDataPointer<ushort> for QString, but
that option wasn't the best one. QArrayDataPointer try to do some
operations using QArrayDataOps and that would expand to unnecessary
code. What's more, the existing code expected to be able to modify and
access the d pointer.
Instead, this commit introduces QStringPrivate (named differently from
QStringData to catch potential users), which contains the three
members. This POD class is also used in QJsonValue to store the
"inlined" QString. QHashedString in qtdeclarative will need a similar
solution.

Instead of using the reference count to store whether the data is
sharable and whether the header is immutable, move the settings to the
flags member. This allows us to save one comparison per deref() or
needsDetach(). It also allows for the possibility of mutable data
pointed to by a static header.

The Mutable flag now contains the information on whether the data this
QArrayData points to is mutable. This decouples the mutability /
immutability setting from the allocation and from the type of data,
opening the way for mutable raw or foreign data.
There are still plenty of places in the source code that check the
size of the allocation when it actually wants d->isMutable(). Fixing
this will require reviewing all the code, so is left for later.
The needsDetach() function is moved to QArrayData and
de-constified. It returns true when a reallocation is necessary if the
data is to be modified.

These flags allow us to determine what type of data QArrayData is
carrying. There are currently only two supported types:
- raw data type: constructed via fromRawData or static data
- allocated data type: regular data done via heap allocation
The QArrayData object is usually allocated on the heap, unless its own
reference count is -1 (indicating static const QArrayData). Such
object should have a type of RawDataType, since we can't call free().
Add GrowsBackward for completeness as well as the StaticDataFlags
default for static data.

In almost all cases, use d->allocatedCapacity() or
d->constAllocatedCapacity() instead of d->alloc, since they do the
same thing (right now). In the future, the functions will be
changed. There is a separate const version because most const code
should not need to know the allocation size -- only mutating code
should need to know that
There are a few cases where d->alloc was replaced with a better
alternative, like d->size. The one case that remains in the code will
be replaced by a different test when it's available.

Instead of stealing one bit from the alloc field, let's use a full

others there, not relevant for now).
This is done in preparation for the need for more flags necessary
anyway.

QByteArray::fromBase64 was liberal in its input, simply skipping

no error reporting, meaning it could not be used to convert
fromBase64 _and_ validate the input in one go.

its input. Since we want to know whether it has succeeded
or not, and the existing fromBase64 overloads do not
allow for that, introduce a new function that returns
an optional-like datatype.

The qdatetime implementation's rfcDateImpl() uses regexes which did
not match its comments; nor did either the regexes or the comments
match what was documented. A review of relevant RFCs suggests we
should revise this in future, probably at Qt 6.
The documentation also only addressed the formats recognized when
parsing a date-time, without indicating how they are serialised or how
dates and times are handled separately.
Added a note to the tests for the read-only formats, to remind the
reader that the RFCs merely recommend recognising these - be
permissive in what you expect and strict in what you deliver.

On NTFS, a junction point can be created and deleted by the mklink and
rmdir commands, respectively. If a directory is not identified
correctly as a junction, then applications will likely try to remove
it using recursive methods, leading to fatal data loss.
With this change, Qt can identify file system entries as junctions,
allowing applications to use the correct file system operation to
remove it.
The test needs to delay the cleaning up of junctions and files it
creates until the checks are complete; since they might fail and make
the test function return prematurely, use a scope guard.
