Remove code for vicep-access

in this version we do not support vicep-access to fileserver partitions.
We also do not support vicep-access to OSD-partitions, but keep the server
side code.
create osdMetadataFile and new check_for_osd_support

During cloening of a volume the osdMetadata file schould be created
whenever a volume has osdPolicy set.

The volserver calls check_for_osd_support when moving an OSD-volume
to another server. Unlike in 1.4 and 1.6 this routine calls an RPC
in the AFSVOLOSD set rather than in AFSVol to keep changes to volint.xg
small.
