7f4511cb7b Networking and repository
Some pom.xml changes to reduce maven-shade-plugin conflicting classes warnings.

Repository now supports SAVEPOINT and ROLLBACK TO SAVEPOINT.
HSQLDB concurrency/transaction model changed from LOCKS to MVCC to help with
 transaction deadlocks/rollbacks.

More XXXs and TODOs added to Block.java for investigation/fix/improvements.
Also used new repository SAVEPOINT feature when validating transactions
 instead of rolling back entire transaction. This fixes problem during
 synchronization where the rollback would undo previously synchronized,
 but not yet committed, blocks!

Transactions orphaned by Block.orphan ARE now added to unconfirmed pile,
 unlike before.

Concurrent lock now prevents simultaneous block generation and synchronization,
 including synchronization via multiple peers.

Lots of new networking code: peer lists, block signatures, blocks,
 blockchain synchronization.

PEERS_V2 message now supports hostnames, IPv6 and port numbers.

Fixed bug with block serialization for transport over network.

0db43451d4 Interim networking code commit in case of dev catastrophe!
DB shape change from v29 to add peer info.
New NetworkRepository to handle above.

Peer handshaking with v2 anti-DoS PoW code.
Handshaking refactored into a state-machine-like enum.
Some peer-related API calls added.

Peers exchange pings, heights, peers.

No actual peer sync yet.

Other changes:

Peer version info taken from Maven build properties/resource file.
AnnotationPostProcessor more resilient when fetching PathItems.
Per-repository session debugging flag that can be toggled at will.
HSQLDBRepository.delete() now returns int so callers can detect
 whether anything was actually deleted.
Some renaming to settings.

4be58514c0 Unify API calls that return lists + offload pagination to repository
API calls that return lists now take limit, offset and reverse params.

API calls that used to return data & optional list (e.g. blockWithTransactions)
now only return base data. The optional lists can be fetched via
a different API call.

Also: SLF4J now routes logging to log4j2 so start up output cleaned up.
Suppressed extraneous Jersey warning about Providers during start-up injection.

Fixed Block so correct block hash and timestamps are generated,
especially when previous/next block versions differ.
Added extra call in BlockTransformer to aid this.

Fixed GenesisTransaction.isValid's incorrect amount test.

Fixed comments in TransferAssetTransaction and incorrect use of BlockChain.getVotingReleaseTimestamp()
instead of BlockChain.getAssetsReleaseTimestamp().

Added new TYPEs to HSQLDBDatabaseUpdates, and set LOB granularity to 1KB for AT use.
Added AT_address column to DeployATTransactions in HSQLDB.
Added ATs, ATStates and ATTransactions tables.
(You will need to discard existing database and rebuild).

Fixed incorrect byte array output in IssueAssetTransactionTransformer,
where Asset "references" were not processed correctly.

Added support for BigDecimal serialization to a byte-array size other than the standard 8.
