Test: media/media-extension-with-fragment.html

* html/HTMLMediaElement.cpp:
(WebCore::HTMLMediaElement::loadResource): Pass the KURL to MediaPlayer, let it extract a
    String when it needs it.

* platform/graphics/MediaPlayer.cpp:
(WebCore::MediaPlayer::load): Take a KURL, not a String. Look for the file extension in the 
    last path component so we don't examine fragments and/or queries.
* platform/graphics/MediaPlayer.h:

LayoutTests: 

* media/media-extension-with-fragment-expected.txt: Added.
* media/media-extension-with-fragment.html: Added.
