commit 20c2e2937980e39373edc4446369c7410aa38585
Author: Marijn Kruisselbrink <mek@chromium.org>

[Mojo Blob URLs] Refactor Blob URL loading for subresources.

This changes the XHR and fetch codepaths to resolve blob URLs earlier
(i.e when the request is created rather than when the fetch is made), in
order to fix bugs where the blob URL is revoked after creating a request
but before fetching.

This also addresses race conditions between revoking blob URLs and
fetching them by resolving a blob URL as soon as possible for subresource
requests.

Not addressed yet are navigation and download requests, that will be
done in follow ups.
