nsIURIWithPrincipal is currently used to retrieve the nsIPrincipal from a BlobURL object. BlobURLProtocolHandler has a hashtable containing, for each blobURL, a BlobImpl and its nsIPrincipal. This patch introduces BlobURLProtocolHandler::GetBlobURLPrincipal() that retrieves the nsIPrincipal from this hashtable. This patch fixes also a bug in how the revocation of blobURLs is broadcasted to other processes. This should be done immediately because each process creates its own timer to revoke them after 5 seconds. An important change is related to NS_SecurityCompareURIs() where, if 1 (or both) of the 2 URIs to compare, is a revoked BlobURL, we will QI its URL to nsIStandardURL and fail out at that point.
