 * Function:  ssize_t read_buffer(datafd, buffer, buflen, timeout_s)
 *
 * Description:
 *	read data from input file desciptor waiting up to timeout_s
 *	seconds before returning data.
 *
 * Inputs:
 *	datafd    - File descriptor to read from.
 *	buffer    - Buffer to read into.
 *	buflen    - Maximum number of bytes to read into buffer.
 *	timeout_s - Seconds to wait before returning what was already read.
 *
 * Returns:
 *      >0	  - Number of data bytes in buffer.
 *       0	  - EOF
 *      -1        - errno == ETIMEDOUT if no data available in specified time.
 *                  errno == ENFILE if datafd is invalid.
 *                  otherwise errno is set by select or read..
