Android 6 and above produces uncompressed native libraries that
are only part of the APK by default. However, Qt had this behavior
explicitly disabled via packagingOptions.jniLibs.useLegacyPackaging
Gradle flag (previously extractNativeLibs manifest flag) because
we didn't support loading libraries directly from the APK.
This patch adds support for reading and loading shared libraries
directly from the APK without having them extracted to disk. Enabling
this might increase slightly the total size of produced APKs, but
saves on disk space after installation and also on update sizes from
the Play Store and slightly faster startups [1][2].
Loading libraries on the Java side is handled by System.loadLibrary().
On C++, dlopen(3) can directly handle library paths relative to the
APK file [3] which would save us the need to add custom code that calls
android_dlopen_ext() [4] which works with compressed libraries then
using AssetFileDescriptor and having to manage its file descriptor
manually.
To ensure proper integration with various Qt APIs and modules, this
adds a QAbstractFileEngine/Iterator implementations to allow reading
and listing APK files. Since, the files are expected to not change,
they are cached once at startup and re-used thereafter. The engine
implementation allows reading the libraries content using Android's
AssetManager. Also, it allows mapping the libraries directly to
memory to allow proper integration with QPluginLoader.
For plugins, the native libs dir inside the APK is added to Qt and
QML plugins search paths.
With this patch, both compressed and uncompressed libs should work,
to ensure this, an auto test is added with 'useLegacyPackaging true'
to make sure both scenarios still works.
[ChangeLog][Android] Add support for uncompressed native libraries
within APKs.

Replace all calls to QtAndroid::activity/service with QtAndroidPrivate

global copy of the activity and service, we can drop the reference right

of a global static QJniObject (62cb5589b3723fe8162e190cd54d9c78929b98d2,
after which declared QtJniTypes became QJniObjects), while
QtAndroidPrivate::activity returns a newly created QtJniTypes::Activity
on each call.
This however makes it also safer, as the QJniObject is then associated
with the calling thread's JNI environment, and we can optimize critical
code paths where it's safe to do so later. Also, QtAndroid's activity
object was never updated, while QtAndroidPrivate's activity is updated
in the updateNativeActivity native method.

LocationChanged event unconditionally triggered invalidateVirtualViewId
call. That call results in TYPE_WINDOW_CONTENT_CHANGED Android event,
which causes a lot of background processing.
That is not correct, because LocationChanged event is generated by
every accessible element, not only the one that has A11Y focus.
This patch checks event->uniqueId(), and processes only events that
come from the focused accessible element.

On Android orientation changes are reported from the
DisplayListener.onDisplayChanged() method, while the screen size
changes are reported from QtLayout.onSizeChanged().
In practice these callbacks come in random order, so rotating the
screen multiple times might result in inconsistent order of signals
and events.
This patch makes sure that size change events always happen before
orientation changes. This is done by caching the new orientation
values and reporting them only when needed. At this point we also
need to use QMetaObject::invokeMethod() for orientation change,
like it is done for geometry change. Otherwise the orientation
update can still be processed earlier than the geometry change.
Also note that at some point we might get an orientation change
without a size change (for example Qt::LandscapeOrientation ->
Qt::InvertedLandscapeOrientation). That is the reason for
isSimilarRotation() helper function.
As a drive-by: ignore size changes with inconsistent values when window
size is reported to have old orientation, while the screen has already
been rotated. In such cases a new size change will be triggered shortly
with normal value.

Screen has 3 parameters:
- physical size
- screen size (or screen geometry)
- available geometry
Before this patch, they were reported in 3 different methods. Screen
size update and available geometry update both were generating the
"screen geometry changed" event, that updated the user-visible
parameters. As a result, at some point we could end up in an
intermediate state, when screen size was already updated, but
available geometry was not yet updated.
This was specially visible while changing the screen orientation:
at some point screen geometry could be reported for the new
orientation, while the available geometry - still for old orientation.
This patch introduces a new method to set all geometry-related
parameters together and generate only one "screen geometry changed"
event. This allows to maintain consistency between 'geometry' and
'availableGeometry' properties of QScreen.
