Servo currently completely ignores `<meta charset>` tags. When we find one with an encoding that is incompatible to the current one, then we should reload the page and start over with the new encoding. A common optimization that has even made its way into the specification is to wait for a few bytes to arrive and inspect them for `meta` tags, so the browser is able to use the correct encoding from the very beginng. In practice, I've run into problems with our WPT harness when reloading the page after `meta` tags. Therefore, this change implement the optimization first, so we never have to reload when running WPT. I've implemented prescanning in a way where we wait for 1024 bytes to arrive or for one second to pass, whichever one happens first. This causes a large number of web platform tests to flip around. I've looked at most of the new failures and I believe they're reasonable. Testing: New tests start to pass.
