3a449bbb69 amended the code to remove
acquiring a lock when waking up a condition variable. It is fine to
not have a lock associated when waking a condition variable; what I
misunderstood was the scope of the lock, which (and this underlines
the importance of commenting _what exactly_ a lock protects, for
each and ever lock) protected both the buffer as well as the counter
of the buffer. This made my reasoning flawed: it is necessary to keep
the lock while notifying, otherwise the counterpart could verify the
condition isn't satisfied and wait (e.g. see numUsedBytes==0), missing
the wake from the other thread (which could arrive between the check and
the wait).
Amends the previous commit.

In no particular order:
* Clean up #includes.
* Document what is protected by the mutex.
* Use explicit, nullptr.
* Use lock managers, not manual calls to lock/unlock.
* Unlock the mutex before notifying the condition variables.
* Condition variables are always meant to be used in a while loop, and
never with a plain if, because of spurious wakeups.
* Don't lock a mutex just to protect a plain integer. We have atomics
for that use case.
* Remove an unneeded signal, therefore also the need of using
Q_OBJECT and the inclusion of the moc-generated file.

Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.
Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.
The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.

The example refines the image by running a number of passes

visible to the user. Set an informational text string on

along with the elapsed time.
The idea is to do the same to the corresponding
Qt for Python example to have some sort of speed comparison
for number crunching.
Add a command line option for the number of passes.
Make the window a bit larger to accommodate the

* When on Android, build a module (shared library), just like qmake.
This requires an additional library destination in the install() call,
but that's ignored on other platforms.

module generation onAndroid.
In order for the examples to see the function in Qt5CoreMacros, three more
additional fixes were required:
* Do the build_repo_end() call _before_ attempting to build the
examples, as we need the build_repo_end() to include QtPostProcess
and complete the creation of all the target config files.
Otherwise the find_package() calls in the examples see something
incomplete.
* Add more QT_NO_CREATE_TARGET guards
* Always call find_dependency on the dependencies, regardless of the
target creation mode. This way a find_package(Qt5 COMPONENTS
Widgets) will still load Qt5CoreMacros.
