Code cleanup for nfs4 utilities:

 - Mark internal routines as static;
 - Eliminate unused parameters where possible, mark __unused for others;
 - Remove unused variables;
 - Use %jd for int64_t values in printf();
 - Add appropriate %d for printf to match its parameter;
 - Rename a variable to resolve conflict with revoke(2);
