HLS: faster switching and pause/resume on low buffer
- when upswitching, discard excessive buffering on low
bandwidth variant, switch to new variant earlier
- when downswitching, report newly found IDR positions
continuously, and switch as soon as new fetcher passes
playback position. This allows us to skip time-consuming
resumeUntil() of old fetcher most of the time
- implement pause/resume on low buffering, and notify
buffering percentage
- buffering parameter tuning, separate pause/resume/ready
buffer level and up/down switch buffer level, boost up
fetcher buffering significantly
