Mac OS X: Fix crash in Harfbuzz-NG

CoreText does not support multithreading, so we would get a
crash in tst_qglthreads. So we disable multithreading for
HB-NG.

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.
