Bryan Schumaker eb1c86b8b5 NFS: rename nfs.upcall -> nfs.idmap
This patch renames the idmapper upcall program from nfs.upcall to nfs.idmap in
the NFS documentation.  This is because the program has been renamed in the
nfs-utils source.

Bryan Schumaker 955a857e06 NFS: new idmapper
This patch creates a new idmapper system that uses the request-key function to
place a call into userspace to map user and group ids to names.  The old
idmapper was single threaded, which prevented more than one request from running
at a single time.  This means that a user would have to wait for an upcall to
finish before accessing a cached result.

The upcall result is stored on a keyring of type id_resolver.  See the file
Documentation/filesystems/nfs/idmapper.txt for instructions.
