Added new service call sub-reason code.

Detail:
  Service_InternetStatus/DHCPInform is issued whenever a response to a
    DHCPINFORM is received.
  Modules which claim sub-reason code 3 (DynamicBootStart) can now alter
    R2 (if they claim the reason code) to contain the return value for
    the Internet module's ioctl handler.  Previously, the Internet module
    always returned EADDRUNAVAIL if the service call was claimed, which
    meant that callers had to use other means to determine whether the
    dynamic boot had completed (eg. by querying the DHCP module directly)
Admin:
  Documentation file LibraryDoc updated with details.
  Required by Internet 5.25 and later.
  Required by DHCP 0.05 and later.

Version 5.18. Tagged as 'TCPIPLibs-5_18'
