qdoc: Use empty common prefix for alphabetical QML type lists

This change allows an empty string to be used as a common prefix
for class/type compact lists, and uses it for QML types as they
do not have a common prefix like public C++ Qt classes do.

This fixes the issue with sorting order for QML type lists.

iOS: Use PROT_READ, not PROT_NONE, for custom stack memory guard

This allows V4 and other garbage collectors to pass through our
custom stack during the mark-phase without triggering access
violations.

testlib: Don't link to IOKit on iOS, it's not part of the SDK

IOKit used to be part of the 5.x and 6.x iOS SDKs, but not officially,
so when Apple in the iOS 7 SDK removed IOKit headers and the library
symlink, our builds started failing.

Android: Don't throw away slow-moving mouse/touch events

When doing slow, precise movements, some devices will report
differences of less than 1 pixel. This would mark the points
as stationary, meaning that Qt would discard them without reporting.

On the three devices I have tested, stationary points are reported with
a 0.0 difference. If any devices are reporting noisy values, it is
still safer to test for equality, since it is much better to report
too many move events than to not report any.
