When writing to alt-data output stream fails for whatever reason, we now try to truncate alternative data and keep the original data instead of dooming the whole entry. The patch also changes how is the predicted size passed to the cache. Instead of a dedicated method it's now an argument of openOutputStream and openAlternativeOutputStream methods which fail in case the entry would exceed the allowed limit.
