/** Initialize the DataLink configuration from Environment variables,
 * or else to defaults.
 * @ingroup DataLink
 * The items configured depend on which BACDL_ the code is built for,
 * eg, BACDL_BIP.
 *
 * For most items, checks first for an environment variable, and, if
 * found, uses that to set the item's value.  Otherwise, will set
 * to a default value.
 *
 * The Environment Variables, by BACDL_ type, are:
 * - BACDL_ALL: (the general-purpose solution)
 *   - BACNET_DATALINK to set which BACDL_ type we are using.
 * - (Any):
 *   - BACNET_APDU_TIMEOUT - set this value in milliseconds to change
 *     the APDU timeout.  APDU Timeout is how much time a client
 *     waits for a response from a BACnet device.
 *   - BACNET_IFACE - set this value to dotted IP address (Windows) of
 *     the interface (see ipconfig command on Windows) for which you
 *     want to bind.  On Linux, set this to the /dev interface
 *     (i.e. eth0, arc0).  Default is eth0 on Linux, and the default
 *     interface on Windows.  Hence, if there is only a single network
 *     interface on Windows, the applications will choose it, and this
 *     setting will not be needed.
 * - BACDL_BIP: (BACnet/IP)
 *   - BACNET_IP_PORT - UDP/IP port number (0..65534) used for BACnet/IP
 *     communications.  Default is 47808 (0xBAC0).
 *   - BACNET_BBMD_PORT - UDP/IP port number (0..65534) used for Foreign
 *       Device Registration.  Defaults to 47808 (0xBAC0).
 *   - BACNET_BBMD_TIMETOLIVE - number of seconds used in Foreign Device
 *       Registration (0..65535). Defaults to 60000 seconds.
 *   - BACNET_BBMD_ADDRESS - dotted IPv4 address of the BBMD or Foreign
 *       Device Registrar.
 * - BACDL_MSTP: (BACnet MS/TP)
 *   - BACNET_MAX_INFO_FRAMES
 *   - BACNET_MAX_MASTER
 *   - BACNET_MSTP_BAUD
 *   - BACNET_MSTP_MAC
