Subject: Fixed problem with detection of end-of-stream for HTTP socket. Problem

Fixed problem with detection of end-of-stream for HTTP socket. Problem
was that if errno happened to be EAGAIN and read returned 0, then
errno was invalid (or has value of previous failed Unix call). Only
if read returns -1, it's appropriate to check errno.
