Merge M52: "When HLS redirects are encountered recreate WebMediaPlayer."

Not all WebMediaPlayer implementations know how to play HLS, and
if the URL does not contain an HLS identifier originally, a later
redirect might break playback if the wrong implementation is
chosen.

When this occurs instead re-trigger Blink's loader with the
redirected source URL that contains the proper HLS tagging.

It's preferred to do this instead of either adding a shim WMP
implementation that choses the real WMP during load() or making
createWebMediaPlayer() block until redirects complete and then
throwing away the data from those connections.

BUG=618109
TEST=Manually tested espn.go.com and adds a new browser test.
