Issue 598: parser fails on timestamp "24:00:00.1234" - prevent the creation of out-of-range time values.

MVStore: up to 65535 open transactions are now supported. Previously, the limit was at most 65535 transactions between the oldest open and the newest open transaction (which was quite a strange limit).

In version 1.4.184, a bug was introduced that broke queries that have both joins and wildcards, for example: select * from dual join(select x from dual) on 1=1

In version 1.4.184, "group by" ignored the table name, and could pick a select column by mistake. Example: select 0 as x from system_range(1, 2) d group by d.x;

the logic that cleared the flag could never be reached, resulting in performance degradation.
Reported by Alexander Nesterov.

In version 1.3.183, indexes that contains columns with a default value generated by a sequence where not used. This includes identity and auto-increment columns. This bug was introduced by supporting "rownum" in views and derived tables.

Using "row_number" or "rownum" in views or derived tables had unexpected results if the outer query contained constraints for the given view.

MVStore: the Recover tool can now deal with more types of corruption in the file. MVStore: the TransactionStore now first needs to be initialized before it can be used.

MVStore: use a mark & sweep GC algorithm instead of reference counting, to ensure used chunks are never overwrite, even if the reference counting algorithm does not work properly.

Fix bug which could generate a NegativeArraySizeException when performing large (>40M) row union operations

H2 Console and server mode: SSL is now disabled and TLS is used to protect against the POODLE SSLv3 vulnerability. The system property to disable secure anonymous connections is now "h2.enableAnonymousTLS". The default certificate is still self-signed, so you need to manually install another one if you want to avoid man in the middle attacks.
