WinRT: Fix multi-touch on PC

The pointer ID was incorrectly interpreted as a device ID, which caused
creating a new QTouchDevice for each touch update and potential crashes
in QtQuick. The handling has now been simplified and aligned with Windows
Phone, treating all touch events as if they originate from the same
device. Given that the native device has no ID, it is not
possible to track the native device between events anyway (even the
pointer values change).

Use XI2 event detail to determine changed mouse button

The button state part of the XI2 events appears to be badly constructed
on some devices and platforms. Even where supported the 'detail' field
of the XI2 events is what we should be reading since it indicates the
button the event refers to and not just the state of all buttons.

Fix crash on startup when running screenreader

For exaple Qt Creator would crash when started and a screen reader (eg
NVDA) is running. This is due to updateAccessibility being called during
the ctor of the TextEdit and on Windows the AT can access properties in
the same call resulting in accessing the text control before it's fully
constructed.

Also make sure to not send accessibility updates for non-widget type edits
since we don't support any accessibility in Qt Quick 1.

Backported from Qt 5.3.1 since it also crashes Qt Creator on startup on
Mac (as soon as accessibility is enabled which may be for various
reasons, and basically any app that uses a QTextEdit).

Ignore expired certificate during certificate validation

OpenSSL has a bug when validating a chain with two certificates.
If a certificate exists twice (which is a valid use case for renewed
CAs), and the first one it hits is expired (which depends on the order
on data structure internal to OpenSSL), it will fail to validate the
chain.

This is only a bandaid fix, which trades improved chain validation
for error reporting accuracy. However given that reissuing of CA certs
is a real problem that is only getting worse, this fix is needed.

[ChangeLog][QtNetwork][QSslSocket] Added a workaround to an OpenSSL problem
that may cause errors when the trust store contains two certificates of the

Fix stateful handling of invalid UTF-8 straddling buffer borders

When a UTF-8 sequences is too short, QUtf8Functions::fromUtf8 returns
EndOfString. If the decoder is stateful, we must save the state and then
restart it when more data is supplied.

The new stateful decoder (8dd47e34b9b96ac27a99cdcf10b8aec506882fc2)
mishandled the Error case by advancing the src pointer by a negative
number, thus causing a buffer overflow (the issue of the task).

And it also did not handle the len == 0 case properly, though neither
did the older decoder.

Scrolling devices should not override touch or tablet devices

XISelectEvents override any earlier set event mask for the same device
ids. This may cause touch devices to stop reporting touch events if they
export scroll buttons or axis.

The patch checks for each scrolling device if they are also a touch
devices and includes the necessary bitmask if they are, and skips
any devices also recognized as tablet devices as they already capture
all relevant events.

In addition tablet event handling will no longer block handling of wheel
button events for scroll devices with the same device id.
