ad250e57c8 Fix issues with payments, asset trades and voting.
Some payments don't always initialize the recipient's
last reference, depending on whether the asset is QORA or not and
what type of transaction is being processed.
Calls to Payment.process/orphan now take boolean to indicate
whether recipient's last reference should always be initialized
regardless of asset.
("initialized" here means setting an initial last reference for
an account if the current value is null/empty/missing)

When matching orders to produce trades, it isn't enough to only
sort orders with best price first. Orders with the same price also
need to be further sorted by earliest order first. (This was
implicitly done in Qora v1). Added additional ORDER BY sub-clause
to achieve this and improved the corresponding table index too.

Converted a lot of logging from simplistic System.out/err.println
to Apache log4j2. Added several "trace"-level logging statements
to aid debugging which can be activated given appropriate
configuration in log4j2.properties.

With voting, detection of previous votes was broken during orphan
as previousOptionIndex was set to 0 instead of null when fetching
a VoteOnPollTransaction from the HSQLDB repository. This was due
to lack of null-checking - now fixed.
Corresponding changes made in IssueAsset and Message
transaction HSQLDB repository classes.

v1feeder now syncs up to block 99055. Block 99056 contains DeployAT.
Orphaning back to block 1 and then resync works without issue too.

e56d8f5e02 HSQLDB issue, resource leak prevention, v1 differences
HSQLDB v2.4.0 had some issue with non-padded, case-insensitive string comparisons.
This is fixed in svn r5836-ish of HSQLDB but yet to be pushed out to new HSQLDB release.
So this commit includes hsqldb-r5836.jar and modified pom.xml/.classpath for now.

No need for duplicate, hidden creatorPublicKey in CancelOrderTransactionData,
CreateOrderTransactionData and CreatePollTransactionData.

Various changes to use more try-with-resources, especially with JDBC objects like
Connection, Statement, PreparedStatement, ResultSet.

Added loads of missing @Override annotations.

Fixed bug in Asset exchange order matching where the matching logic loop
would incorrectly adjust temporary amount fulfilled
by the "want" asset amount (in matchedAmount)
instead of the "have" asset amount (in tradePrice).

Disabled check for duplicate asset name in IssueAssetTransactions for old v1 transactions.

In HSQLDB repository we now use ResultSet.getTimestamp(index, UTC-calendar) to make sure we
only store/fetch UTC timestamps. The UTC-calendar is made using static final TimeZone called
HSQLDBRepository.UTC.

To keep asset IDs in line with v1, Assets.asset_id values are generated on-the-fly in HSQLDB
using a "before insert" trigger on Assets table. Corresponding code
calling HSQLDBRepository.callIdentity() replaced with SELECT statement instead.

Moved most of the HSQLDB connection properties from the connection URL to explicit code in
HSQLDBRepositoryFactory.

Fixed incorrect 'amount' lengths in PaymentTransformer, as used by MultiPayment and Arbitrary
transaction types.

Added support for mangled arbitrary transaction bytes when generating/verifying a v1 transaction signature.
In v1 Arbitrary transactions, bytes-for-signing are lost prior to final payment (but only if there are any payments).
Added corresponding code for multi-payment transactions in the same vein.

7da84b2b85 Arbitrary Transaction support + various fixes
NOTE: requires HSQLDB built from svn rev 5836 or later

Fixed BuyNameTransactionData constructors not picking up nameReference.

Added new "orphan" tool to regress blockchain back to specified block.

Added new Block constructor for when receiving a block from the network.
Fixed Block generatingBalance/forging code to be compliant with v1.
Added logging of transactions that fail validation during block validation.

Fixed buyer/seller balances not being updated during name purchase.

Generally replace BigDecimal.compareTo expressions with "<operator> 0" form.
e.g. instead of someBigDecimal.compareTo(anotherBigDecimal) == 1
we now have someBigDecimal.compareTo(anotherBigDecimal) > 0

Fix amounts involved in BuyNameTransactions.

Renamed Transaction.calcSignature to .sign

Refactored Transaction.toBytesLessSignature to TransactionTransformer.toBytesForSigning,
which itself calls subclass' toBytesForSigningImpl,
which might override Transaction.toBytesForSigningImpl when special v1 mangling is required.

Corrected more cases of NTP.getTime in transaction processing
which should really be transaction's timestmap instead.

Fixed HSQLDB-related issue where strings were padded with spaces during comparison.
Some column types no longer case-insensitive as that mode of comparison
is done during transaction validation.

Added missing option_index column to CreatePollTransactionOptions which was causing
out-of-order options during fetching from repository and hence signature failures.

Added unit tests for v1-special mangled transaction signature checking.

Removed checks for remaining bytes to ByteBuffer in various transaction transformers'
fromByteBuffer() methods as the buffer underflow exception is now caught in
TransactionTransformer.fromBytes.

Corrected byte-related transformations of CreatePollTransactions that were missing
voter counts (albeit always zero).

Corrected byte-related transformations of IssueAssetTransactions that were missing
duplicate signature/reference (v1-special).

Added "txhex" tool to output transaction in hex form, given base58 tx signature.

Added "v1feeder" tool to fetch blocks from v1 node and process them.
