[Tizen IVI] Hide title bar in fullscreen mode.

Currently, Crosswalk for Ozone-wayland shows title bar by default
on Tizen IVI. As a result, when webapps enter fullscreen mode using
HTML5 fullscreen API, their title bar still exists.

This patch allows to hide title bar in fullscreen mode.

It depends on the following commit in chromium-crosswalk:
https://github.com/crosswalk-project/chromium-crosswalk/commit/dfd0f4be34bd81f7a9ea9346c324191c694b7319

Bug: XWALK-896
[Android] Provide embedding API for Crosswalk.

A new embedding API is designed for providing capabilities to embedders.
This can provide functionalites and their APIs as an Android library.
This patch mainly re-define API and re-construct classes and their
relationship. To keep current capability, lots of legacy code are also kept
without big changes. Main changes are:
1. New APIs: XWalkView, XWalkUIClient, XWalkResourceClient, XWalkPreferences,
XWalkNavigationHistory, XWalkNavigationItem and XWalkJavascriptResult.
2. Legacy APIs are used by tests. Need to refine them.
3. Remove unused code for http authentication.
4. Re-construct some duplicated code in core tests.
This issue is still for XWALK-1041. It's not finished yet. Need to implement
remaining TODOs and refine the description of APIs.
[Android] Fix xwalk_app_template crash issue after rebasing to 35

The apps which were packaged with xwalk_app_template will crash.
It's because the icudtl.dat was not packaged into the apk.

[Application][Tizen] Move extension process logic to a standalone thread

The previous EP(ExtensionProcess) & launcher merge patch changed the launcher's
main thread glib message loop to Chromium message loop which is MessagePumpOzone
in Tizen. This leads to some asynchronous DBus function and signals cannot be
successfully called.

To divide the old launcher logic(mainly communicate with DBus) and new EP
logic this patch added a new XWalkLauncherExtensionService running in a separate
thread.

[Android] Enable app cache on Android by default

Currently, app cache flag is enabled by default, but it can't work if
app cache path is not set explicitly. Actually, Chromium doesn't explore
the interface to setting app cache directory.

Crosswalk should not have this limitation, when no app cache is specified,
we should use chromium default cache path instead.
