Log:
Minor fixups to dbi backend:

* dbi_conn_error_flag is deprecated, replace with dbi_conn_error
  (Thanks, Christian).

* Switch from OS-determined HOST_NAME_MAX to locally defined
  GNC_HOSTNAME_MAX so that the field is always 255 regardless of what
  OS creates it.

* Use G_OS_WIN32 instead of naked WIN32
