This patch removes the CONFIG_NFS_USE_NEW_IDMAPPER compile option. First, the idmapper will attempt to map the id using /sbin/request-key and nfsidmap. If this fails (if /etc/request-key.conf is not configured properly) then the idmapper will call the legacy code to perform the mapping. I left a comment stating where the legacy code begins to make it easier for somebody to remove in the future.
