0512c3e257 Add _UNICODE define to MSVC and MinGW mkspecs
System headers like tchar.h need the _UNICODE define, not UNICODE.
While qplatformdefs.h already provides _UNICODE when UNICODE is
defined, users might want to include tchar.h without Qt includes.

3f1548ae82 Restore behavior of using libEGL and libGLESv2 as default for angle
As Qt applications using OpenGL are linked against these libs, merging
them into QtANGLE by default (780105f906)
was a binary incompatible change. This change restores the default
behavior to the one before given change.

If the user wants the libraries to be merged, he can pass
combined-angle-lib to configure.

f1a23a5467 Basic Vulkan enablers
For Android, Windows and xcb. Verified on Win10 with NVIDIA, Win10
with AMD, Android with Tegra K1, Android aarch64 with Tegra X1, and
Linux aarch64 with Tegra X1 (Jetson TX1, L4T).

Introduce QPA-based Vulkan library loader, core function resolver, and
instance creation support. In addition to creating a new VkInstance,
adopting an existing one from an external engine is supported as well.

The WSI specifics are hidden in the platform plugins. Vulkan-capable
windows use the new surface type VulkanSurface and are associated with
a QVulkanInstance.

On Windows VULKAN_SDK is picked up automatically so finding vulkan.h
needs no additional manual steps once the LunarG SDK is installed.

[ChangeLog][QtGui] Added support for rendering to QWindow via the Vulkan
graphics API.

0f1b6acab7 x86: Add detection of the AES and SHA New Instructions
The AES instructions were first introduced with the Westmere shrink
(22nm) of the Nehalem architecture. The SHA instructions are still
pending on Intel architecture, but is available on AMD family 17h (gcc
argument -march=znver1).

Both features operate on SSE registers, so that's why the MSVC command-
line argument is the SSE2 one and the configure-time tests depend on
features.sse2.

The qmake feature names end in "ni" because "aes" and "sha" are too
simple and could clash with other uses. The QT_COMPILER_SUPPORTS_ macro
doesn't have the "NI" suffix because it has to match the GCC/Clang
predefined macro.

780105f906 Merge ANGLE's libEGL and libGLESv2 into QtANGLE
This is needed in order to be able to specify a custom location of
the ANGLE libs, and enables us to perform a LoadLibrary of ANGLE libs
by just having the absolute path to QtANGLE.dll as the argument to
LoadLibrary().

Previously, we had two ANGLE libraries: libEGL and libGLESv2. libEGL hard
linked against libGLESv2.  If we wanted to load libEGL from a custom
location, we couldn't load libEGL by calling LoadLibrary with the absolute
path to libEGL, because libEGL had problems finding libGLESv2.  One
solution to that could have been to call SetDllDirectory() with the path
to the ANGLE libs before calling LoadLibrary("libEGL.dll"). Since the DLL
directory would point to both ANGLE libs, this would ensure that the libGLESv2
was also found.  Unfortunately, this approach is not thread safe
(SetDllDirectory will affect all subsequent LoadLibrary(Ex) from the same
process). Therefore, we chose to merge the two libraries into one to
circumvent the whole problem.

At the same time, this patch also enables loading of two different ANGLE
libraries into the same process at once without renaming them: This was
not possible before because libEGL hard linked to libGLESv2.dll.  When
libGLESv2.dll was already loaded, the second instance of libEGL would
simply link against the already loaded version of libGLESv2.dll.

This behavior is documented in the LoadLibraryEx documentation on MSDN:
"If the string specifies a module name without a path and more than one
loaded module has the same base name and extension, the function returns a
handle to the module that was loaded first."

ar error: `u' modifier ignored since `D' is the default (see `U')

Warning message includes word "error" so QtCreator processes it as

`ar' command-line option `u' might be dropped safely because it is
unnecessary. Option `c' is added to suppress extra `ar' warnings.

Move it from bootstrap.pro into qt_module.prf so it will apply to any
other bootstrapped libraries, like libQmlDevTools.

Variable called "SPLIT_SECTIONS" because -fdata-sections could be added
in the future, if it proves to be a benefit.

19501b0731 Fix win32 mkspecs
Instead of checking for dynamicgl in QT_CONFIG, which is apparently

Dynamic GL is Windows-only for the time being so this should be sufficient.

97c187da3c Dynamic GL switch on Windows
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.

5fcf441392 Fix '=' alignment and replace tabs in *.conf (whitespace only change)
Replace all tabs with proper space characters and consistently align
the '=' characters. The default alignment for the '=' of 25 characters
has been left as is to get a minimal diff. Lines with the '=' further
to the right and those belonging to 'proper code (TM)' have not been
touched.

The work was mostly done using the following python script (might
come in handy again...):

import sys, re
indent_eq = 25 + 0*4 # 25 characters was the most widely used indentation for the '=' character
p = re.compile(r'(\w+)[ \t]*([\-\+]?)(=$|= )[ \t]*(.*$)')

    with open(fn, 'r+') as f:
        lines = []
        nl_count = 0
        continuity_indent = None
        for l in f:
            m = p.match(l)
            nl = l
            if m:
                n_spaces = max(m.start(3), indent_eq - 1) - len(m.group(2)) - len(m.group(1))
                if m.group(2) and m.start(2) >= indent_eq-1 and m.start(2) % 4 == 0:
                    n_spaces -= 1 # left-shift '+=' by one if the '+' is aligned to a multiple of 4
                n_spaces = max(1, n_spaces) # we want at least one space before '='/'+='
                nl = m.group(1) + ' '*n_spaces + ''.join(m.group(2,3,4)) + '\n'
                continuity_indent = nl.find('= ') + 2 if l[-2] == '\\' else None # remember indent on '\\$'
