Only first previously deleted entry was recognized, leading hsearch_r to think that there was no previously deleted entry. It then conluded that a free entry was found, even if there were no free entries and it overwrote a random entry.
This patch makes sure all deleted or free entries are always found and also introduces constants for the 0 and -1 numbers. Unit tests to excersise a simple hash table usage and catch the corruption were added.

setenv i 0 while true; do setenv v_$i $i setenv v_$i setexpr i $i + 1 done
