[Runtime] WARP security mode should be enabled by default.

According to the W3C widget spec, http://www.w3.org/TR/widgets-access/,
it said: In the default policy, a user agent must deny access to network
resources external to the widget by default, whether this access is
requested through APIs (e.g. XMLHttpRequest) or through
markup (e.g. iframe, script, img). Means if there's no access tag in
config.xml, all external requests should be blocked.

[Runtime][Tizen] Fix hwkey issue after M36 rebase.

Crosswalk fetches hardware key events from MessagePumpOzone before.
However, MessagePumpObserver is deprecated in M36, it is replaced by
PlatformEventObserver, which is installed on a PlatformEventSource.
Besides, the ozone message pump is also removed in M36 and is
substituted by the default message pump based on libevent instead.

This patch fixes above issue and now we support 'hwkey' feature again.

[Runtime] Make application running with isolated storage partition

Tizen WRT spec and Chrome both require applications running with private
storage. Which means the application running data like local storage, cookies,
app cache, GPU cache will move to a standalone storage directory.

When an app is uninstalled, it is not safe to remove the corresponding
directory directly. So we will mark the uninstalled apps in DB and garbage
collect them when next time Crosswalk starts up.
[Tizen] Add xwalk-launcher support for full app exec path cmdline

Currently the AUL service can't find correct app info by using

method. It needs full app exec path to query the corresponding app info.

This patch will change argv to full exec path when app launched with
xwalk-launcher <app-id>.
