GCC 4.9 now allows us to #include any and all intrinsics headers, not
just the one for which we're compiling code, a behavior that ICC and
MSVC have had for some time. With that, we're able to have the functions
for different targets in the same source file. See the GCC manual:
http://gcc.gnu.org/onlinedocs/gcc/Function-Multiversioning.html
This functionality is notified by the QT_COMPILER_SUPPORTS_HERE(XXX)
macro, which indicates that all the intrinsics from
QT_COMPILER_SUPPORTS_xxx are available and enabled. To complement, a
QT_COMPILER_SUPPORTS(XXX) macro is also added.
Unlike ICC and MSVC, GCC requires a special function attribute, which
will also cause code optimization. That's the QT_FUNCTION_TARGET macro.
Note: because of the absence of the target attribute, ICC and MSVC will
not generate instructions with the VEX prefix unless they only exist
with the VEX prefix or if -mavx / -arch:AVX are enabled.

Do not link against ICU on Windows, unless it is explicitly requested
('-icu' configure option). This removes the QtCore->ICU dependency
if ICU was detected in the configure environment.
So far ICU has been used in Qt Core for
- support of a larger set of codecs (805 instead of 135)
- more accurate QLocale functionality (QLocale::toUpper,
qLocale::toLower)
- string collation
However, for all functionality there are also backends using the
Windows API/Registry (QLocale, QCollator), or built-in
codecs that are part of QtCore. Since the ICU dependency is quite heavy
(3 libs with about 25 MB) it seems sensible to not require it by default.
QtWebkit is unaffected, since it has it's own ICU check.
[ChangeLog][Windows] Changed configure defaults so that Qt5Core does not
link against ICU libraries anymore. Pass '-icu' to enable it.

The patch introduces a new build configuration on Windows which
can be requested by passing -opengl dynamic to configure.
Platforms other than Windows (including WinRT) are not affected.
The existing Angle and desktop configurations are not affected.
These continue to function as before and Angle remains the default.
In the future, when all modules have added support for the dynamic
path, as described below, the default configuration could be changed
to be the dynamic one. This would allow providing a single set of
binaries in the official builds instead of the current two.
When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are
never defined. Instead, the code path that has traditionally been
desktop GL only becomes the dynamic path that has to do runtime
checks. Qt modules and applications are not linked to opengl32.dll or
libegl/glesv2.dll in this case. Instead, QtGui exports all necessary
egl/egl/gl functions which will, under the hood, forward all requests
to a dynamically loaded EGL/WGL/GL implementation.
Porting guide (better said, changes needed to prepare your code to
work with dynamic GL builds when the fallback to Angle is utilized):
1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to
differentiate between desktop and ES where needed. Keep in mind that
it is the desktop GL header (plus qopenglext.h) that is included,
not the GLES one.
QtGui's proxy will handle some differences, for example calling
glClearDepth will route to glClearDepthf when needed. The built-in
eglGetProcAddress is able to retrieve pointers for standard GLES2
functions too so code resolving OpenGL 2 functions will function
in any case.
2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds,
but never "angle" or "opengles2".
3. The preprocessor define QT_OPENGL_DYNAMIC is also available in
dynamic builds. The usage of this is strongly discouraged and should
not be needed anywhere except for QtGui and the platform plugin.
4. Code in need of the library handle can use
QOpenGLFunctions::platformGLHandle().
The decision on which library to load is currently based on a simple
test that creates a dummy window/context and tries to resolve an
OpenGL 2 function. If this fails, it goes for Angle. This seems to work
well on Win7 PCs for example that do not have proper graphics drivers
providing OpenGL installed but are D3D9 capable using the default drivers.
Setting QT_OPENGL to desktop or angle skips the test and forces
usage of the given GL. There are also two new application attributes
that could be used for the same purpose.
If Angle is requested but the libraries are not present, desktop is
tried. If desktop is requested, or if angle is requested but nothing
works, the EGL/WGL functions will still be callable but will return 0.
This conveniently means that eglInitialize() and such will report a failure.
Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will
tell which implementation is chosen.
The textures example application is ported to OpenGL 2, the GL 1
code path is removed.
[ChangeLog][QtGui] Qt builds on Windows can now be configured for
dynamic loading of the OpenGL implementation. This can be requested
by passing -opengl dynamic to configure. In this mode no modules will
link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will
dynamically choose between desktop and Angle during the first GL/EGL/WGL
call. This allows deploying applications with a single set of Qt libraries
with the ability of transparently falling back to Angle in case the
opengl32.dll is not suitable, due to missing graphics drivers for example.

This is the first step in implementing an in-place conversion of QString
to QByteArray. This requires ref-qualifiers in member functions so we
know that we have an rvalue QString.
Converting from UTF-16 to Latin1 always requires half the memory.
For conversion from UTF-16 to UTF-8, the typical string will also need
the same memory or less: characters from U+0000 to U+007F consume one
fewer byte; characters from U+0080 to U+07FF and from U+10000 to
U+1FFFFF occupy the same space in UTF-8 and UTF-16; it's only the ones
from U+0800 to U+FFFF that consume more space in the UTF-8 string.
For the locale's 8-bit codec, we can't be sure and the code (currently)
needs to go through QTextCodec anyway.
This requires a #define set before #include'ing "qstring.h". However,
since qstring.h is included by the QtCore PCH, we need an extra qmake
compiler without the PCH flags to compile this .cpp.
After this change, the distribution of calls in QtCore, Network, Gui,
and Widgets is as follows:
const & &&
toUtf8 31 (74%) 11 (26%)
toLatin1 79 (77%) 24 (23%)
