Subject: [PATCH 02/15] avformat/http: Return EIO for prematurely broken
connection
Currently, a prematurely broken connection normally leads to the same
EOF, as a completed successful transfer. However, enabling reconnect
changes this logic, and leads to the return of EIO.
This patch unifies that logic, leading to the return of EIO for premature
disconnect, regardless of setting of "reconnect".
