Subject: src/lket.5.in: document nfs trace hooks

tapset/nfsd.stp, tapset/nfs_proc.stp, tapset/nfs.stp:
Change NFS file identifier. Change NFS version data type
from String to INT. Add version variable to nfs_open
and nfs_release.

LKET/iosyscall.stp:
change log_iosyscall_sync() be sync with different timing methods.

LKET/utils.stp:
add reset_maxaction() since there are too many functions called inside "probe begin".

LKET/nfsd.stp, LKET/nfs_proc.stp, LKET/nfs.stp:
New trace hooks for NFS, including both NFS client and server side activities.

LKET/register_event.stp:
Add the register event calls for NFS trace hooks.
