add missing "format" function attributes
For most of our functions that take printf-like formats, we use gcc's __attribute__((format)) to get compiler warnings when the functions are misused. Let's give a few more functions the same protection. In most cases, the annotations do not uncover any actual bugs; the only code change needed is that we passed a size_t to transfer_debug, which expected an int. Since we expect the passed-in value to be a relatively small buffer size (and cast a similar value to int directly below), we can just cast away the problem.
