[whatwg] URL encoding for XHR and Workers.

Update:Ian Hixie pointed to places in spec which specify very clearly that
all URLs in workers will be encoded in UTF-8 (including query part) before
sent over wire regardless of whether it is a new worker, importScripts or
XHR URL.

The "encoding of the script" is set to UTF-8 as prescribed by Workers spec,
section 2.5, step 3. This overrides the 'inherited' encoding from the parent
document and even http header for the worker's script. At the same time,
HTML5 spec, section 2.5.1 says URL that came from script has encoding of the
script.

So the FF beta behavior (encode URLs using the encoding of the top-level
document that created the first level worker) seems to be incorrect, I plan
to file a bug on it.
