eae8abbc18 Fix detecting the system path
The normalize function don't do well it's job.
Given a path like that,  the regexp "/[^/]+/.."  will match 3 times
 /usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.2/../../../../include/c++/4.8.2
                                      [       ][    ][         ]
The second match is wrong as it will remove /../..

Use sub instead of gsub which only remove one match at the time.

30e677e2bb QNX: Allow creation of parentless child windows
There is no reason why a parentless window from a Qt perspective needs
to be a screen application window.  There are some cases, such as the
BB10 dialog service whose windows are always parented by a window in
another process.

Ideally one would have a means to indicate a child window was wanted that
had no other side effect (i.e. the rest of Qt would ignore).  The use of
Qt::Dialog is not ideal as some code does pay attention to this type given
the number of bits available for window type, it is not reasonable to add a
new one.  The use of Qt::Dialog seems safe since it is hard to conceive of
a window of type Qt::Dialog wanting to be a top level window.  If in future
it is required to have a parentless, child window that is not of type
Qt::Dialog one can simply define some additional way of signalling this.

5fcee88097 Abuse const_cast in QStringBuilder to get a little more performance
Without this const_cast, the call to QString::data() or
QByteArray::data() will cause a call to detach(), which is totally
unnecessary since we've just allocated data a couple of lines before.
Since we know we're the owner of the only reference, we can skip the
detach attempt.

603eac2dfb d3dcompiler_qt: Place compiler options in the shader file name
The compiler service needs to know what options to pass to the compiler,
and these options can affect the outcome of the shader blob. Runtime
compiled shader output must match this file name in the binary directory.
Pre-compiled shader blobs (e.g. those placed in a resource file) are
permitted to drop options from the file name if the implementor can
ensure the blob is compatible with the target.

Defines are not written out as options, but written into the shader
source, and therefore affect the cache key.

6e836271fd QNX: Make window groups work reliably
Window group related code worked previously only for the 'root'
window and other windows that had no parents (which then joined
the window group of the root).

Introduced a new function joinGroup that makes the group related
calls, this can both join and leave groups.

Default group joining is performed in setVisible now rather than
setScreen.  The advantage of setVisible is that one can rely on it
getting called at some point but it is also possible to create and
interact with a QQnxWindow before it is called.  This allows
the default group handling to be overridden via the native
interface.  If the group is set (or explicitly not set) then the
default handling is not done.

joinGroup is also called from setParent so that if the parent window
is changed the window joins the parent group.

328f2f9c35 eglfs: Move reusable functionality to eglconvenience
The cursor implementation is generic GL(ES) code that should be shared
by all the present and future egl-based embedded platform
plugins. Follow the pattern of QEGLPlatformContext and move this class
into eglconvenience as QEGLPlatformCursor.

Similarly, the common bits from the context implementation context are
moved back to EGLPlatformContext.

eglconvenience has now base classes for integration, screen, window,
etc. too. By using these, eglfs becomes much smaller and cleaner. This
also paves the way for creating new, separate EGL-based platform
plugins for Android, embedded Linux, etc.

Also added some documentation to each of the base classes.

devicediscovery is now fixed to be usable on any platform. The
implementation in this case is naturally a dummy one. This finally
allows using it from anywhere without myriads of ugly ifdefs.

93154216ca Fix BlackBerry10 build on NDKs prior to 10.2.1
This commit adds a dependency checking for a recently
introduced define. On NDKs 10.2.1 and later it compiles
with support for VIRTUALKEYBOARD_LAYOUT_ALPHANUMERIC.
NDKs 10.2.0 and earlier do not know this define
and therefore it will be ignored.
This is necessary because there is no newer NDK
publicly available than 10.2.0.
Assuming pure QNX SDKs are missing the define completely,
we are only including it on recent BB NDKs.

87d2fa5f84 eglfs: Allow using a different framebuffer device
Right now /dev/fb0 is hardcoded. This is not ideal. Therefore
QT_QPA_EGLFS_FB is introduced. This environment variable can be set to
a different framebuffer device. Once it is set, eglfs will use the
specific device. This is similar to linuxfb's fb=... plugin parameter.

The actual behavior depends on the board-specific implementations.
For now only iMX6 has real support. It extracts the index from the
device name as bind the EGL display to the corresponding framebuffer
using the vendor-specific fbGetDisplayByIndex(). Other hooks can
follow suit later on.

With this patch eglfs is at least on par with linuxfb, meaning that,
if the board supports it, different apps can run on different screens.

894ce8aaab Android: Don't register main thread on loading library
When building with debug, all SLOT or SIGNAL macros will
expand to a function call, and then function will call
QThreadData::current(), which will set
QCoreApplication::theMainThread if it has not already been
done. Since Qt Widgets has these macros in the static
initialization of the library, we would register the
Android main thread as the main thread of Qt, which would
mean that the actual application object was created on
a different thread than the main thread. This caused warnings
to appear, and also triggered a race condition which
caused widget applications to sometimes show a black screen
instead of content on startup when run with the OpenGL plugin.

45673221ae Add detection of C++1y features (probably C++14)
I've added the most interesting features. I've skipped three features
that GCC and Clang will support:
  N3323  contextual conversion tweaks
  N3653  member initialisers and aggregates
  N3664  clarifying memory allocation

Of those, only N3653 brings a new syntax, so it could be added later.

407eee51e6 Optimize INV_PREMUL
Our inverse premultiply is rather unoptimized. It's major weakness is
using three divide operation which are the slowest integer operations.

This patch reduces the three divisions to just one but using an
approximation that is accurate for all uchar values.

The patch also adds a general short-cut for alpha==255.

Together these improvements makes it 2 to 16 times faster depending on
how many 0 and 255 alpha values are encountered.

Those paths need not be in INCLUDEPATH: qmake always adds them to the
compiler command-line and we should match the behavior if we expand
INCLUDEPATH here.

3c375a76a1 Automatically turn on SSE2 code generation throughout Qt
...unless the user passed the -no-sse2 option to the compiler.

[ChangeLog][Important Behavior Changes] Qt now automatically generates
code for processors supporting SSE2 on i386 platforms. To disable
this, pass the -no-sse2 option during Qt configuration. Since this
feature has been present on CPUs for 10 years and since Qt no longer
checks for runtime support for SSE2, we strongly encourage users to
leave the default setting on for best performance.
 - For Linux distributions that must retain support for CPUs without
   SSE2, we recommend doing two builds of Qt and installing the
   SSE2-enabled libraries in the LIBDIR/sse2 directory. Tools,
   plugins, and examples are not affected.
 - See discussion on the Qt development mailing list:
   http://lists.qt-project.org/pipermail/development/2013-November/014085.html

These two functions used to cause a runtime detection of the CPU

commits, there's no runtime detection of either SSE2 or Neon support,
so there's no point in attempting runtime detection.

1b12c0608b Remove runtime detection of Neon on ARM CPUs
Now the only way to enable Neon support is to change the mkspec.

[ChangeLog][Important Behavior Changes] Qt no longer checks for
support for the Neon FPU on ARM platforms at runtime. Code optimized
for Neon must be enabled unconditionally at compile time by ensuring
the compiler supports Neon. You may need to edit your mkspec for that.

d006e69da6 Remove runtime detection of SSE2
If the compiler supports SSE2, we'll use our SSE2-optimised code
unconditionally. Runtime detection is left for SSSE3 code.

The SSE2 codebase is big and thus a timebomb if an inline function
gets leaked out and run without runtime check. In reality, it's
extremely unlikely people running CPUs without SSE2 support are
running Qt 5 at this moment (they're either too old or too new,
e.g. Intel Quark).

The SSSE3 codebase is a lot more manageable.
