+/* Code for dynamic hash table routines
+ * Author - Eric Young v 2.0
+ *
+ * 2.2 eay - added #include "crypto.h" so the memory leak checking code is
+ * present. eay 18-Jun-98
+ *
+ * 2.1 eay - Added an 'error in last operation' flag. eay 6-May-98
+ *
+ * 2.0 eay - Fixed a bug that occurred when using lh_delete
+ * from inside lh_doall(). As entries were deleted,
+ * the 'table' was 'contract()ed', making some entries
+ * jump from the end of the table to the start, there by
+ * skipping the lh_doall() processing. eay - 4/12/95
+ *
+ * 1.9 eay - Fixed a memory leak in lh_free, the LHASH_NODEs
+ * were not being free()ed. 21/11/95
+ *
+ * 1.8 eay - Put the stats routines into a separate file, lh_stats.c
+ * 19/09/95
+ *
+ * 1.7 eay - Removed the fputs() for realloc failures - the code
+ * should silently tolerate them. I have also fixed things
+ * lint complained about 04/05/95
+ *
+ * 1.6 eay - Fixed an invalid pointers in contract/expand 27/07/92
+ *
+ * 1.5 eay - Fixed a misuse of realloc in expand 02/03/1992
+ *
+ * 1.4 eay - Fixed lh_doall so the function can call lh_delete 28/05/91
+ *
+ * 1.3 eay - Fixed a few lint problems 19/3/1991
+ *
+ * 1.2 eay - Fixed lh_doall problem 13/3/1991
+ *
+ * 1.1 eay - Added lh_doall
+ *
+ * 1.0 eay - First version
