Packaging: re-enable XDG_Shell for Tizen
The Weston has been upgraded to 1.5 and XDG_Shell basics for Weston 1.5 have been in oz-wl.
So we think it's time to re-enable it now. Meanwhile some related issues are under fixing. More changes will come in.
[Android] Use reflection layer in xwalk core for runtime usage

As now there is reflection layer between xwalk core and xwalk
core internal, there is no need to use the one between runtime
and runtime client for runtime usage.

After this patch, most facilities to support shared mode will be
moved from runtime to xwalk core. Besides, runtime_java will be
merged into runtime_client_java.
XWalkRuntimeLib.apk will keep the name unchanged, but its package
will be org.xwalk.core which was org.xwalk.runtime.lib previously.

TODO: Extension is still using reflection in runtime layer which
will be refined in future commits.
[Android] Move extension manager out to runtime layer

Extension in runtime layer (XWalkExtensionClient) was
directly using XWalkExtensionAndroid, which has core
internal dependency.
It should be based on the extension provide by xwalk
core.
Move all the classes for runtime extension to runtime
client package and remove the reflection layer which
is not between XWalkExtension and XWalkExtensionInternal.
[Tizen] hardcode OZONE_WAYLAND_USE_XDG_SHELL env in service file

This change tells ozone wayland backend
that shell is supporting unstable xdg-shell.

This is needed for by tizen's Application.hide().

Alternative would be store this var in system wide env
ie: /etc/profile/crosswalk.sh
And eventually force a login shell (sh -l -c "...")
in this service file.

But for performance concern it's hardcoded there,
this change may be reverted later
if Tizen sessions decide to use login shells then it will work same.

Refer to this page for xdg-shell integration in Tizen :

Expose real path of Virtual Root (native file system)

Add a function, getRealPath(), to native_file_system object. Developer
passes virtual root name to this function and get full path of this
virtual root.

BUG=XWALK-2455
Make 'xwalkctl' Tizen-only

SSIA. Crosswalk on desktop does not need xwalkctl, as it does not
provide application management.

Remove application storage from the desktop code path

Remove application storage from the desktop code path
(make it Tizen-only). The AppliactionServiceTizen object
was added to own the application storage.

This patch also encapsulates application launching within
the ApplicationService object, and contains multiple code
cleanups.
