Coverity threw an error that in the else branch, the expression
colorTableRGB16[tableSize - 1] accesses uninit'ed data. The working
theory is that it fails to perform the implication
isEmpty() → size() == 0
This patch, therefore, checks for size() == 0 instead of isEmpty(),
which is hardly less readable and might help Coverity understand the
code better.
Then again, Coverity might not understand that the tableSize can never
be negative. If that's the case, another patch will be needed, but
let's try the simpler solution first.

Originally on macOS it would override any tab text color with white
for the active tab as it would set it directly on the option palette
inside the style code. This would cause it to ignore any changes done
by the user in a changed option, via setTabTextColor or in a proxy
style. Therefore the setting of the color should be done when the style
option is initialized and only if the tab text color has not been
set by the user.
This has the added effect of making it easier to change the color for
tabs via a stylesheet since it will not be overridden in the style but
setup correctly in the option instead.

This is an improvement for the following reasons:
- Should mutex locking allocate any kind of resource,
unlocking in reverse order will free those resources
in inverse order, which helps typical allocators.
- If the lock pair is contended, by unlocking in the
same order as locking, we were allowing the waiting
thread to wake up to take the first lock just to
find that the second lock is still held by someone
else.
The order of unlocking has no influence on the correct-

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.

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.

QXcbCursor had a "cache" of cursor handles. Unfortunately, as QXcbCursor has its
lifetime tied to the screen, this cache grew unbounded whenever the cursor was
set: this could be witnessed worst when repeatedly setting the current cursor to
a different pixmap each time.
We fix this by keeping the cursor cache only for the "regular" shaped cursors
that are often shared between windows, working on the assumption that custom
cursors are generally specific only to a given window. This makes the lifetime
of the bitmap cursors much more clear: they are tied to that window, and when
the window is destroyed (or changes cursor), so too is the bitmap cursor
destroyed (if set).

The problem is that the casts are done outside the switch that
determines the event's type, so for any given event object, at least
any two of the casts are invalid.
This could actually be a real problem, because it's trivial for a
compiler to prove that these three lines unconditionally invoke UB, so
it has all the right in the world to decide to drop the complete rest
of the function, using this line of reasoning:
1. The only way for these three casts not to be UB is if event ==
nullptr.
2. If event == nullptr, then event->type() invokes UB, so event cannot
be nullptr.
3. The only way both can be true is if this code path is never
taken. I can thus assume that
object == state && event->type() == QEvent::Timer
is always true, drop the check and execute the if block
unconditionally (I need to call QEvent::type(), to satisfy the
as-if-rule, but I needn't check its return value).
Fix by moving the casts where they belong: into each case of the
switch, where the type of the event has been checked to match the
target type of the cast.

Fix by replacing Q_Q with the the equivalent expression for QDialog.
We can't re-use QDialogPrivate::q_func() here, since that is private,
and probably should stay like that.
Also fix an invalid member call in
QColorDialogPrivate::canBeNativeDialog():

by accessing the data member directly instead of through the Public API.
Fix the same code in QFileDialog, even though the autotest coverage is
too limited for UBSan to point that one out explicitly.
This commit amends abe8b4ab9b, in which
it should have been included in the first place...

(full backtrace originates in tst_QWidget::testDeletionInEventHandlers(),
testing key events).
Fix is simple: just perform the cast before delivering the event.

We checked if we had seen the interface by looking into seenInterfaces
and seenIndexes, but we never updated those variables with what we saw
in this block.
This fixes the reporting of PPP interfaces as well as TUN/TAP virtual
interfaces.

Writing to solid overwrites part of the gradient input messing up later
lines. In particular repeating gradients tended to be broken.
Tested by lancelot (once the baseline is correct).
