I just try to use avio to read stream by http protocol.
But if the server responds too late, avio_read will return timeout, and
the only way I can do is close it and reopen.
Of course I can set a large timeout, but it's hard to decide which
timeout value is large enough.

If we meet timeout when reading network resource, avio_read will set
[eof_reached] to 1. And this prevent caller to retry since avio_read
do nothing and just return if eof_reached == 1.
If timeout was triggered by a small ‘timeout’ setting from user, just
change the ‘timeout' configuration. If it was triggered by a system call,
it’s likely to be in a state of not recoverable. Could you share more
details about the issue this patch trying to solve?
