Tune allocation and comparison of nodes
representing temp files. This improved CPU performance of
'sort -S 1 *.[ch]' by 17% on my host.
(struct tempnode): name member now uses struct hack.
(temphead): Now a pointer, not a structure. All uses changed.
(create_temp_file): Allocate node using struct hack.
(zaptemp): Free node using struct hack. Use pointer comparison, not
string comparison.
