Fix abnormal consumption of mobile data
Problem: When user is watching http live streaming video, user does some
operation to let browser run in the background, but mobile data is still
consumed abnormally.
Root cause: When browser runs in the background, browser will call
mediaplayer pause function, which would pause video renderer. But if network
speed is fast and buffered data is more than PlaylistFecher::
kMinBufferedDurationUs, data can't be consumed and it will call
postMonitorQueue() frequently after delayUS time's up. At this time, if http
server returns error when refreshPlaylist, delayUs will be 0 because
mLastPlaylistFetchTimeUs is not updated, which will cause postMonitorQueue
and refreshPlaylist more frequently, and consumes more mobile data.
Solution: On PlaylistFetcher::onMonitorQueue(), if refreshPlaylist returns
error, it calls notifyError and then end this playback.
Bug: 123665682
Test: play http live streaming video, pause this playback, then close Wi-Fi
to simulate accessing http server error
