Adds INFORMATION_SCHEMA views for the transaction log:

TRANSACTION_LOG
TRANSACTION_LOG_ENTRIES
TRANSACTION_LOG_TRANSACTIONS

Adds a new user-defined function:

PRINT_TRANSACTION_MESSAGE(filename, offset)

Adds tests for all of the above

Implementation notes:

An indexer now runs when transaction messages are applied
to the transaction log.  It creates a simple index of the
transaction log entries.  This index is used when the
information schema views' fillTable() method is called.
