Additions/Changes:
- Add QML's WorkerScript type
- Add QFuture + QFutureWatcher
- Clarify differences between QtConcurrent::run() and the map/filter/
reduce functions
- Reword table headings
- QThreadPool accepts a priority parameter too (although it's not OS-
level, unlike QThread)
Rows removed from the table:
- QThread can be "reused" and "task oriented" too, depending on the
program design. It's hard to convey this in a table though, so I just
removed it.
- "High level" is ambiguous and doesn't really help readers choose a
tool to use.

Although the C++ language builds in the 'wchar_t' datatype, the
library functions such as wcscmp() which manipulate them are not
automatically available. For these, inclusion of the <cwhar> header
is still required.
This changeset fixes build breakage observed from failure to include
the requisite system header for accessing wcscmp() and other related
functions on non-GNU standard C++ library implementations.

Those features have slightly different behavior as the C++11 keywords
that MSVC 2012 officially supports. When compiling in C++/CLI mode,
the "virtual" keyword must be present too.
We have not actually tested whether the official MSVC 2012 support for
C++/CLI still requires the virtual keyword. This is just going on the
assumption that C++/CLI follows the C++11 spec.

* The explicitly linked support libraries like gnustl_shared, etc. can be
linked as private libs, there's no need for them to show up in the .prl files of our libraries.
* Removed the explicit linkage against libsupc++, which is a static library whos symbols
are also available in libgnustl_shared. It is only needed when linking against gnustl_static,
which we fortunately don't do.
For QtQml on Android this is more than just cleanup. Without the first change, the libgnustl_shared
comes early on in the link line, because it is a dependency of for example Qt5Network. Anything that
qml.pro itself adds to LIBS comes afterwards. That is not intended, we want libgnustl_shared to come
at the end of the link line, in order to make sure that the linker finds an overriding symbol from
another library earlier in the link line first.
The explicit linkage against libsupc++ affects the same, as that's the library
that contains the symbol we want to override locally (__cxa_end_cleanup).

The compiler inserts __cxa_guard_acquire, __cxa_guard_release calls around
the initialization of local static objects to make the initialization
thread safe. However, the implementation of _cxa_guard_acquire in Apple's
libc++abi uses a global lock, which means that only one thread can
initialize a local static variable at a time. This can be a problem if
e.g. the constructor of the variable is blocking while waiting for another
thread ...
This behavior has caused issues so far in webkit and the qml debugging
infrastructure. Better avoid it by using our custom lock implementation.

Unhandled touch events cause QGuiApplication to generate synthetic
mouse event by default. This is good but on embedded systems, where
there is no windowing system and thus the platform cursor
implementation relies solely on QGuiApplication pushing position
updates via pointerEvent(), this causes odd behavior when there is
both a touchscreen and a mouse present.
The patch changes QGuiApplication to call pointerEvent() only when the
event is not synthetic. This will prevent the mouse cursor from
jumping to the position of the touch when using the touchscreen. It is
needed also because moving the mouse later would make the cursor jump
back to its previous, "real" mouse position anyhow which is extremely
annoying. This is now avoided.
