Fix streaming errors

Browse source 
Streaming a file (through mplayer for instance), the socket would
block, because mplayer fills its buffer sequentially.
We would've never gotten to a write(.., n) == n.

Instead, do it like we read from files and accept the fact clients
can accept data chunk-wise, too.

The reason why this error went unnoticed is that I added a faulty
printf-directive (%ls for ssize_t), which silently produced
no output.
Thanks to sin for fixing the %ls -> %zd error, as it made me look
at the code again.
