[Android] Fix the regression issue of http authentication on chromium 34.

Based on chromium 34, the http authentication cannot work, while
it works on chromium 32, this is because Chromium 34 starts to
support the out-of-process iframe, RenderViewHost is replaced by
RenderFrameHost, while in XwalkLoginDelegate, webcontents is still
gotten via the RenderViewHost, which causes the corresponding UI
thread for http authentication not to work. This fix resolves this
issue by replacing RenderView with RenderFrame for http authentication.

[Tizen][Runtime] Fix session bus issue under service mode.

Tizen 3.x and Tizen 2.x have different DBUS_SESSION_ADDRESS values.
For Tizen 2.x, DBUS_SESSION_ADDRESS points to
'/run/user/$USERNAME/dbus/user_bus_socket',
while for Tizen 3.x, DBUS_SESSION_ADDRESS points to
'/run/user/$UID/dbus/user_bus_socket'.

Since Crosswalk switches to Tizen 3.x, we need to use the latter one.

widget application by the default 'index.html' path

Previously, Field.isAccessible() is used to detect whether

Fix it by using Modifier.isFinal(getModifers()) instead.
