scpReceiveFile hangs forever if the source file is empty

I guess there is not much more to be said here. I can provide simple test program if desired.

I am starting to believe this is a bug in libssh2. Adding a debug message before and after channel_read_ex shows that it is the call to channel_read_ex that hangs.

Possibly libssh2/libssh2#105 (closed because of inactivity, not fixed).
