... and avoid detach()ing potentially large data for just
preserving the QPlatformPixmap::pixelType().
A QBitmap differs from a QPixmap (its base class, urgh)
by always having a data != nullptr and a Bitmap pixel
type, yet load() was unconditionally setting 'data' to
nullptr on failure, turning a QBitmap into a non-QBitmap.
Fix by move-assigning a null QBitmap instead of resetting
'data'.
Add some tests.

Unlike layouts and spacer items, a QWidget is-not-a QLayoutItem.
QWidgetItem simply wraps the QWidget, so in QFormLayout::setWidget(),
we allocate a widget item for the widget passed, and hand that down
to Private::setItem() for adding to the various data structures.
Private::setItem() has a bunch of guard clauses, though, that return
without deleting the item.
A test triggered this code path and made asan complain.
This is just one part of a larger problem: QFormLayout::setLayout()
normally takes ownership of the layout passed, because QLayouts own
their QLayoutItems, and QLayout is-a QLayoutItem. But setLayout()
fails to live up to the owner role when it fails to add a layout,
and there's no easy way for the API user to check for success.
A fix for this breaks tst_qformlayout, and while those checks that
break deserve to be broken, I'll refrain from proposing the larger
fix for 5.6 LTS, but will propose it for 5.8 or 5.9 instead.
This fix here only fixes the leak in setWidget() by adding a bool
return to Private::setItem() informing Private::setWidget() of the
need to manually delete the item it allocated for the widget.

In some cases, when QNetworkReply::encrypted is emitted,
QNetworkReply::sslConfiguration is not yet initialized, in particular
certificate chain is empty, which breaks the documented usage of
'encrypted' to perform additional checks on certificate chain.
It looks to be caused by the fact that QHttpNetworkReply is originally
associated with 0th QHttpNetworkConnectionChannel, and this association
is not updated if HTTP pipelining is not used. Therefore, a reply on
channel >0 might arrive before reply on channel 0, and then using ssl
configuration from channel 0, which not made it through handshake, is
not usable.

The fix is trivial, but the patch adds a new QSettings tests that iterates most
of the QMetaTypes and verifies that storing and retrieving them again gives the
same value. This is a more complete test than the testVariantTypes tests, which
is limited to a subset of the QVariant types. The new tests borrows logic from
the QMetaType test machinery.
QSettings has been Q_ENUM'ified in the process, for improved debug output.
Note that on backends such as the INI backend, the metatype of the QVariant read
from the settings will be a string, so it won't match the input QVariant type,
but the result of converting that to the original value type should still work.

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.
