The credentials callback reads the username and password via scanf into fixed-length arrays. While these are simply examples and as such not as interesting, the unchecked return value of scanf causes GCC to emit warnings. So while we're busy to shut up GCC, we also fix the possible overflow of scanf by using getline instead.
