bcached: add support for concurrent readers

In the case of multiple concurrent readers, bcached return invalid
information. The reason was that answers were issued to successive
readers, before the first reader had a chance to fill-in the data.

Fixed this by adding queues of readers to be notified when the data
are filled by the first reader.
