IosSafeHttpDataSource: log the bounded DataSpec at open() for diagnosis

vc=17 still 403s even with buildUpon().setLength() bounded ranges.
Add Log.i tracing so we can see the exact position, length, and URL
that ExoPlayer's data-source layer is asking for, and capture inner
HttpDataSource exceptions before they propagate.
