Added qt_examples_begin() and qt_examples_end() macros to setup the
example list so it can be re-used in other projects.
When cross-compiling, we also need to set
CMAKE_FIND_ROOT_PATH_MODE_PACKAGE to BOTH in order for find_package()
to work correctly.
Removed support for building the whole qtbase/examples folder as a
standalone project. Building examples is only supported when building
the whole of qtbase (qtbase + examples together) or each individual
example is built separately against an installed Qt version.

We introduced WrapOpenGL to link against either desktop GL or GLESv2
depending on the GL feature in QtGui. This works "fine", with two
caveats:
(1) find_package(WrapOpenGL) must be called after
find_package(Qt5Gui) in order for the feature check in
FindWrapOpenGL.cmake to work. That's error prone.
(2) More and more places are popping up, in particular examples,
where GL linkage is required due to inline functions in Qt that
forward to GL functions - such as on Android.
This in particular explains the qmake behavior of making the GL
linkage (desktop _or_ GLES) a public dependency of QtGui, so only
Gui linkage is required.
Those two aspects combined are the nail in the coffin of FindWrapOpenGL
and it would seem much easier to simply make the Desktop GL vs. GLES
decision once in Gui's CMakeLists.txt and let Qt5GuiDependencies.cmake
propagate this well. This allows us to get rid of plenty of special
cases as well.

This came about trying to remove the Java-style iterator. It was used to
iterate in reverse order, something QMap can't do, easily, due to lack
of rbegin()/rend(). Instead of writing ugly loops, use a vector of pairs,
fill it, sort it, then iterate over that one in reverse.

The old code iterated over the peer list, inserting active peers into
a QSet, curiously not stopping to search for clients if it had already
determined the peer to be active.
It then iterated over the peers again, storing the indexes of the
peers it had determined to be active in the first loop, in a QList.
It _then_ iterated over the index list, in reverse, calling removeAt()
on the peers list.
<sean parent>That's a remove_if!</sean parent>
The twist is, that only some maximum number of inactive peers should
be removed, just enough to bring the number of peers below a
predefined number.
To solve, use a lambda that keeps track of the number of times it has
returned true, returning false once the count drops to zero. We can't
use a mutable lambda here, since the STL algorithms are allowed to
copy the predicate as many times as they wish, and, indeed, remove_if
is commonly implemented by calling find_if. But the standard
guarantees exactly one application of the predicate per element, so we
can assume that we're not called again on the same element, and
therefore keep a reference to an external count.
With this, what was a horrible mess becomes a single call to remove_if.
Also change a while(--n) c.removeFirst() loop to a single call of
range-erase.

This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.
This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.
For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.
The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.
The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.
Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.
In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any
scope, the targets on which the property is set, have to be GLOBAL.
Also for applications and other modules to find all required third
party libraries, we have to install all our custom Find modules, and
make sure they define INTERFACE IMPORTED libraries, and not just
IMPORTED libraries.
