PR13546 Cont'd: Fixed failing test cases
Since we introduced a random seed to the hash function,
certain tests that printed results in an unordered
fashion could now fail, since the order is not necessarily
the same from run to run. These tests have been fixed and now
print in a certain order as to avoid those errors.

PR13546 - Improve Map Hashing
- Made str_hash() in map.c more hashy.
- Introduced a runtime random seed to the hash calculations
to reduce the chance of deliberate hash collision inducing
attacks.
- Made the HASH_TABLE_SIZE depend on MAXMAPENTRIES, rather than
just a static 256. This effectivly increases the size of the
hash table.
