Add patches for avoiding webkit crashes under node context.
Add patch to allow restarting of renderer process on purpose.
Update patches to fit latest chromium.
Add patch to turn sandbox error message to warm warning.
Add patch to disable renderer hang monitor when page is unloading.

We're doing some GUI work like asking for confirmation in the
beforeunload handler, so it's very likely that the renderer may seem
unresponsive. The default behavior of chromium is to close page, which
is of course not the thing we want.
Make symbol exporting work on Windows.
Export ui/views library.
Export symbols of WebView(ui/views/controls/webview).
Also include webview in the dependencies.
Add the CONTENT_IMPLEMENTATION definetion.

For targets that uses content module but is not part of it (for example
the webview target), we need to define CONTENT_IMPLEMENTATION to fix
linking errors.
web_dialogs is a dependency of webview, export its symbols.
Build the views module as static library.
