MediaSource duration attribute should not be equal to Infinity when set to a value greater than 2^64.

Comment on attachment 309056 [details] Patch You can't just change the behavior of MediaTime (such as allowing it to represent double values > 2^64) without defining what happens with math operations between a rational MediaTime and a double outside 2^64. What does it mean to do `MediaTime(1,2) * MediaTime(1e303)`? Also, please add API tests to verify this new behavior.

Thanks for the comments. In uploaded patch, I modified MediaTime so that rational MediaTime is converted first to double for math operations between a rational and double MediaTime. The precision of `MediaTime(1,2) * MediaTime(1e303)` math operation is thus the same as for the double operation (`0.5f * 1e303`). I added new API tests to verify the new behavior.
