NIO storage: the nio: prefix was using memory mapped files instead of FileChannel.

<h2>
Version 1.1.109 (2009-03-14)
</h2>
<ul><li>
The optimization for IN(...) is now only used if comparing a column with an index.
</li><li>
User defined functions can now be deterministic (see CREATE ALIAS documentation).
</li><li>
Multiple nested queries in the FROM clause with parameters did not always work.
</li><li>
When converting CLOB to BINARY, each character resulted in one byte.
Now, the text is parsed as a hex as when converting VARCHAR.
</li><li>
New experimental NIO storage mechanism with both FileChannel and
memory mapped files. To use it, use the file name prefix nio: or nioMapped:
as in jdbc:h2:nio:~/test. So far it looks like NIO storage is faster on Mac OS
but slower on some Windows systems. Thanks a lot to Jan Kotek for the patch!
</li><li>
The functions BITOR, BITAND, BITXOR, and MOD now accept
and return BIGINT instead of INT.
</li><li>
Could not use the same linked table multiple times in the same query.
</li><li>
Bugs in the server-less multi-connection mode have been fixed.
</li><li>
Column names could not be named "UNIQUE" (with the quotes).

New system function TRANSACTION_ID() to get the current transaction
identifier for a session.

Use the Java service provider mechanism to register file systems and function libraries.
