... early spring-cleaning, leaving one block of virtual
root debug code that was inappropriately conditioned on
Q_XCB_DEBUG; it now gets its own define.
Removed Q_XCB_CALL:
1) I don't know anyone who actually uses it.
2) Enabling this feature (via Q_XCB_DEBUG) fails to build
(and has been like that for about 1 year).
3) There are better ways to debug X11 client message exchange
(see xtrace for example).
4) Using Q_XCB_CALL is a very fragile approach. Grep for
example for xcb_change_property and you will see that
half of the calls are not wrapped with the Q_XCB_CALL
macro.
This patch also removes the Q_XCB_NOOP macro. It's unclear
what its purpose was. There was a TODO comment in qxcbeglcontext.h
suggesting removal of this macro as well. Its evaluation of its
parameter, even without Q_XCB_DEBUG, had no side-effects, so its
removal should be harmless.

Move non-monitor-specific members of QXcbScreen to QXcbVirtualDesktop:
they relate to an X screen rather than to a monitor.
It allows to save some memory and X server callings that were
previously made for each monitor.

... to improve readability and reliability.
This change introduces macros Q_XCB_REPLY and Q_XCB_REPLY_UNCHECKED
that allow to replace couples of xcb cookie/reply callings by
a single "calling" of a macro. The macros wrap the reply in
std::unique_ptr thus preventing the need to free it manually.
The following C++11 features are used:
- variadic macros
- std::unique_ptr
- auto type deduction

Very large 1080p TVs or any display which is running at an abnormally
low resolution can have a DPI lower than 48, which means that
qRound(dpi/96) will result in a 0 pixel density, causing critical
issues for applications using Qt::AA_EnableHighDpiScaling.
Make sure that we always have a pixel density of at least 1 to allow
applications not having to worry about such displays.

This is the simplest of the patch series: Q_FOREACH took a
copy, so we do, too. Except we don't, since we're just
catching the return value that comes out of the function
(RVO). We can't feed the rvalues into range-for, because
they are non-const and would thus detach.

This patch improves support for non-32bit screen configurations on X. The
patch mostly touches the xcb platform plugin but the changes to the glx
convenience functions do affect e.g. the offscreen plugin as well.
Since QWindow instances are now by default of type RasterGL instead of
Raster the majority of all windows are in fact instances of QXcbGlxWindow.
This means that the eventual QSurfaceFormat that we use is chosen based on
the available OpenGL configurations. Here the GLX config resolution code
did not do a very good job in trying to find the closest match relative to
the requested QSurfaceFormat, instead preferring higher bit depths.
This is an issue since many configurations support 32-bit windows even
if the screen itself has a root window with depth 16. In particular,
servers supporting both GLX and Render are very likely to have such
visuals. Particularly affected are remote X connections - even if the
application itself makes no use of OpenGL at all!
The changes introduced by this patch are as follows:
1. Improve the GLX visual selection logic
2. Improve the xcb visual selection logic
3. Remove duplicated visual lookup for OpenGL-enabled windows
4. Configure the default QSurfaceFormat to match the primary screen depth

If no screens are available, windows could disappear, could stop rendering
graphics, or the application could crash. This is a real use case in several
scenarios: with x11vnc, when all monitors are physically disconnected from a
desktop machine, or in some cases even when the monitor sleeps. Now when the
last screen is disconnected, it is transformed into a fake screen. When a
physical screen appears, the fake QScreen is transformed into a representation
of the physical screen. Every virtual desktop has its own fake screen, and
primary screens must belong to the primary virtual desktop. It fixes updating
screen geometry on temporarily disabled screens in the middle of the mode
switch.
Expected results: Windows don't disappear, the application doesn't
crash, and QMenu is displayed on the appropriate screen.

The simple mapping of dividing each position by the
devicePixelRatio does not work when screens have different
DPR. If the low-DPR screen above or to the left of the high-DPR
screen, the geometries will overlap in the Qt coordinate system.
This change introduces a new mapping where the origin of each screen
does not move. This mapping is not perfect: it will have gaps between
contiguous screens. However, it will keep non-overlapping screens
non-overlapping in the Qt coordinate system.
Since there is no longer a simple linear coordinate transform, we
have to add screen-dependent mapping functions, and distinguish between
local and non-local coordinates. A side benefit is that the code is
now easier to read, since we remove most manual coordinate transformation.
We also have to cache the screen of each window: since we send resize events
before screen change events, we cannot rely on QPlatformWindow::screen()
(which is set from the screen change event).

The virtual desktop may be composed of several outputs which are
represented by the QXcbScreen class. XSettings are related to
the virtual desktop, so introduce a QXcbVirtualDesktop class and
store QXcbXSettings in it.

Querying X server for data can be very expensive, especially when there
are multiple processes querying it at the same time (which is exactly what
happens when screen configuration changes and all Qt applications receive
XRandR change notifications). This patch is aiming to reduce the number of
queries to X server as much as possible by making use of detailed information
available in the RRCrtcChangeNotify and RROutputChangeNotify events.
Firstly, the backend now does not rebuild all QXcbScreens on any change (which
involved the very expensive xcb_randr_get_screen_resources() call), but only
builds the full set of QXcbScreens once in initializeScreens(), and then just
incrementally updates it.
Secondly, it avoids querying X server for all screens geometry as much as
possible, and only does so when CRTC/Output change notification for a particular
screen is delivered.
As a result, handling of all XRandR events on screen change is reduced from tens
of seconds to less then a seconds and applications are better responsive after
that, because we don't block the event loop for long. The X server is also more
responsive after the screen change, since we are not overloading it with requests.

If a QWindow has never been shown, it has no platformWindow (it's null).
So it's a valid condition and we need to be sure that the pointer isn't
null before dereferencing it.

Some existing debug output required recompiling with Q_XCB_DEBUG.
Being able to enable this debugging in the field will help with
troubleshooting any remaining screen management issues.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

Don't crash; restore windows when all screens are removed and re-added.
xcb: on configure notify, check for screen change: it may be that a
window belonging to a screen which was removed has now gotten mapped
to the new screen. On screen change, send a synthetic expose event,
because the real expose events already happened.
