piece_availability()
--------------------
::
void piece_availability(std::vector<int>& avail) const;
Fills the specified ``std::vector<int>`` with the availability for each
piece in this torrent. libtorrent does not keep track of availability for
seeds, so if the torrent is seeding the availability for all pieces is
reported as 0.
The piece availability is the number of peers that we are connected that has
advertized having a particular piece. This is the information that libtorrent
uses in order to prefer picking rare pieces.
