On some recent Windows versions, GetLastError() may also return
NO_ERROR instead of ERROR_IO_PENDING during an overlapped write
operation to a pipe. This was confusing the state machine in
Server.cpp so that replies to commands were scheduled but were
never actually output.

The checkProg() function was separating a command from its parameters
by splitting at the first space. This was a problem if the command
was specified with a full path containing spaces. Now the checkProg()
function separates a command from the parameters by splitting at the
first non-quoted space. So, it suffices quoting a path to solve the
issue.
Qt 5.2 introduces the possibility to place a checkbox on a QMessageBox,
so we need no longer to use our own crude dialog.

Since qt5_use_modules() is removed from QT5 (as spotted
by Jürgen Spitzmüller), we had to create own version
of this macro.
According to this page:
http://doc.qt.io/qt-5/cmake-manual.html
the way to replace use of qt5_use_modules() for module "_mod" and target "_target"
is to use
1.) cmake_minimum_required(VERSION 3.1.0)
2.) find_package(Qt5${_mod} CONFIG REQUIRED)
3.) target_link_libraries(${_target} Qt5::${_mod})
The last one sets all reguired libraries, compile flags and needed includes for the ${_target}

Apparently, a new paragraph is started after a float even if
no blank line is actually present. So, account for this fact.

This is detected when an undo group is open and contains at east one
element. This means indeed that changes are in progress. Note that the
group is in general opened in GuiApplication::dispatch. The code there
is changed to ensure that the group is closed before updating the
screen.
This patch is experimental. It is expected to be replaced in master by
a more complete solution. It could in the meantime be backported to 2.3.x.
Fixes bug #11159.

The problem is that popping dialogs during reload can cause paint
events for which we are not ready. If this does not work, then we
can introduce a new flag, besides 'busy', for that case. But busy
does not seem to be used very widely, so hopefully this works.
Note that when paintEvent is triggered on macOS, the least we can do
is to copy our backing store to the screen.

Completion uses a complicated async scheme based on timers to update
itself. This is probably not necessary anymore and is fragile to
event order changes.
This is what happens with the new painting scheme. Therefore the
asyncHideXXX() methods have to be made more robust and detect whether
completion state has changed by the time they are triggered.

When an image has to be loaded a second time and the cache
is not used or the image is not in the cache, its preview is
going to be regenerated again. Hence, if the same image
appears more than once on screen, avoid requesting simultaneous
generation of the same preview.
