add the possiblity of faking the uid and the gid in the nfs context.
uid and gid value are read from env variables LD_NFS_UID and LD_NFS_GID.
This can be useful on "insecure" enabled NFS share to make the server
trust you as a root.
Few lines added to the README to document the feature.
add hook on : __fxstatat(), __fxstatat64(), fchmodat(), fchown(),
chown(), fchownat() to support new implementation of chmod and to add
support for chown
The old nfs_[f]stat calls are deprecated. Convert to the newer
nfs_[f]stat64 call that takes struct nfs_stat_64
