mdb_info.mi_adxs[] should be a hash table.  It is indexed by
AttributeDescription.ad_index, which can be > MDB_MAXADS.

Currently back-mdb dumps core with 'attributeoptions foo-' in slapd.conf
when ldapadding an ldif which does

	dn: l=e$i,o=adxs
	objectClass: locality
	st;foo-$i: bar

	# optionally:
	dn: l=e$i,o=adxs
	changetype: delete
 
for i = 0...66000.
