Update WebKit to r44544.

1- WorkerThread::create() now takes a WorkerLoaderProxy parameter, which I
implemented in a stub fashion on WebWorkerImpl.  I'm sure the WebWorker guys
will fix this up properly.

2- Removed expirationDate and setExpirationDate members of WebURLResponse
consistent with their removal from WebCore::ResourceResponseBase.  The
corresponding logic for computing cache eviction time is now part of WebCore.

3- Added wtf/DateMath.{h,cpp} to the build.

TEST=covered by existing tests, I hope!
BUG=none
