Implement NPAPI HTTP Redirect handling. This basically supports the NPAPI URL redirect

notifications which are sent out from the browser while processing URL requests issued
by the plugin via the NPN_GetURLNotify and NPN_PostURLNotify APIs.

For more info please see https://wiki.mozilla.org/NPAPI:HTTPRedirectHandling

As part of this CL we also block cross origin 307 POST url redirects.

Test=Covered by NPAPI UI test GetURLRedirectNotification
