 * @brief SFTP handling functions
 *
 * SFTP commands are channeled by the ssh sftp subsystem. Every packet is
 * sent/read using a SFTP_PACKET type structure. Related to these packets,
 * most of the server answers are messages having an ID and a message
 * specific part. It is described by SFTP_MESSAGE when reading a message,
 * the sftp system puts it into the queue, so the process having asked for
 * it can fetch it, while continuing to read for other messages (it is
 * inspecified in which order messages may be sent back to the client
