Browser: add to support additional website format

Google original browser can handle additional website format
url like "tel:/mms:/mmsto:/sms:/smsto/rtsp:/mailto:/".
But browser can't handle the website inputed by user.

Add the handle url function to handle the "rtsp://" website
which was inputed by user.
This is a requirement from carrier.
