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.

Add QGenericArray to simplify operations. This class can be shared by
other tool classes. If there is nothing else to share it, we can move
the code onto qvector.h. The one candidate is QList.
All tests pass and valgrind is good.

If a small string (1 or 2 chars) would require a JSON escape sequence
when writing out the string, the code could write out of bounds of the
byte array. Fix that by always allocating at least 16 bytes of space.

This requires that the allocation functions return two pointers: the d
pointer and the pointer to the actual data.
Ported QArrayDataPointer & SimpleVector to the inlined size & data.
For now, the size and offset members are not yet removed from
QArrayData, to let QVector, QByteArray and QString compile unmodified.

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

CapacityReserved (even though the allocate() function will store some
others there, not relevant for now).
This is done in preparation for the need for more flags necessary
anyway.

For that reason, rename QArrayData::Default to

Just to simplify a few operations, like detecting when a QChar* or char*
coming from a QString or QByteArray, respectively, were null data.
While you're not supposed to dereference the pointer returned by
QVector::data() unless you know that the array is non-empty, that is
permitted for QString and QByteArray. That is, QString().constData()
must return a valid pointer to a null QChar.

It was setting the system zone ID if it somehow managed to find a
match for an empty zone name; that makes no sense.
A case-insensitive comparison seems reasonable for the "this isn't
just a default zone object, used because the name I asked for isn't
recognized" check.
It set m_id after it had checked everything, where it could just as
well have used m_id as the variable in which to record whether its
check has succeeded already.
It was using the name it was asked for, rather than the one this ended
up being mapped to, which is probably a better name to use for
it. (This should only differ in case.)

The qdatetime implementation's rfcDateImpl() uses regexes which did

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.
