Correct network state and ready state reporting.

For network state, make it return "loading" for everything that's not a file source since our cache does not yet reliably support caching the full media w/o need for a network.

For ready state, correctly handle seeks to drop from HaveEnoughData down to HaveMetaData until the seek completes.  Also implement the seeking() function.

BUG=18975
TEST=none
