The linker complains that some symbols were compiled with different visibility
settings when linking host_build tools such as the import scanner. As it turns
out, we do CONFIG += hide_symbols for static libraries (such as bootstrap or
qmldevtools) but naturally not for the final program source code. It appears
symbol visibility is not of importance for static libraries in host builds (as
opposed to static libraries later linked into shared libraries), therefore this
patch removes that.

The dynamic builds (-opengl dynamic) are now functional on Windows.
In such a build no components in Qt link to any OpenGL libraries directly
and qmake will not automatically add any such libraries to the
applications' makefiles. Instead, the libraries are chosen and loaded
during runtime and applications are expected to use QOpenGLFunctions
instead of direct OpenGLfunction calls.
Set the environment variable QT_OPENGL to desktop or angle to skip testing
and force the given implementation. The application attributes (AA_UseOpenGLES
and such) are also taken into account.
The testing logic is same as before: We try to load opengl32 and
resolve a shader related function. If this fails, ANGLE is chosen. This
allows utilizing full desktop OpenGL on systems that have proper drivers,
while a transparent fallback to ANGLE will be done automatically for
systems that don't. The latter includes also remote desktop connections.
Software rendering via Mesa llvmpipe is supported too. The fallback is
automatic on systems where the desktop test fails and ANGLE fails to load
or initialize (e.g. due to missing libs like d3dcompiler), as long as a
suitable patched build of Mesa is available.
[ChangeLog][QtGui] Dynamic OpenGL implementation loading is now supported
on Windows. This requires Qt to be configured with -opengl dynamic.

always copy the file to the build folder at qmake
time, any later attempts to modify the source file

A better solution is to just reference the custom
plist directly from the Xcode, without modifying it.
This change will also stop unixmake2 from assigning the
default plist to QMAKE_INFO_PLIST, since we need to
know in the xcode generator if the variable was set in
the project or not.

Qt sometimes report that the selection anchor is placed before

When pressing backspace, iOS will select the letter that should be
deleted, and then call "deleteBackwards". If holding down backspace
for a while, it will start selecting whole words instead.
Since we reported negative ranges during this process, it caused
artifacts and stray letters to be drawn.
