Improve Browser performance by 1-2%. To address domain sanity bug,

http://b/issue?id=1022797, we decoded/encoded the url for each request. As
the url can be long, getBytes() and String.init are taking 1.5% in nytimes.com
and 2.4% in cnn.com. By doing a simple URL encoding test, we can shave 1-2
secs thread time during loading.
