8f7c954f5a Proxy private keys are now SHA256(shared secret only) instead of SHA256(shared secret + public keys).
HTML/JS in src/test/resources/proxy-key-example.html updated accordingly.

Add handshake status to output of API call GET /peers

Add/correct @ApiErrors annotations on some API calls.

Add API call POST /admin/orphan (target height as body)
to force blockchain orphaning for when node is wildly out of sync.
Added support for above to BlockChain class.

BlockGenerator now requires a minimum number of peers
before it will generate any new blocks.
See "minBlockchainPeers" in settings.

Controller now requires a minimum number of peers
before it will consider synchronizing.
See "minBlockchainPeers" in settings.

Old "minPeers" entry in settings.json no longer valid!

Networking now allows both an outbound and inbound connection
to a peer although will use the outbound connection in preference.

Networking checks peer ID of inbound connections to detect,
and resolve, peer ID clashes/theft.

0259702df2 Fix generating X25519 shared secret.
X25519 shared secrets now match those generated by libsodium.

New tests show that shared secrets are the same using either set
of private+public key combinations.

Changed proxy private key generation from using simple SHA256
of shared secret to using SHA256(shared secret + both public keys).

Added a temporary "BouncyCastle25519" shim class to provide missing
key conversion from Ed25519 to X25519.

a316b8a810 Potential HSQLDB deadlock fix
After opening repository connection with RepositoryManager.getRepostory(),
any 'read' from repository (e.g. SELECT) starts the transaction
even though HSQLDB documentation states there are no shared/read locks
in MVCC concurrency model.

The work-around for this is to 'reset' HSQLDB's in-transaction flag
by performing a ROLLBACK (Repository.discardChanges) immediately
after acquiring the blockchain lock (which is used to ringfence
changes that might collide like these).

Also adding an extra check to prevent payments to nonexistent AT
addresses as it touches Transaction.

126e651f27 Change sync consensus to favour lower-value block sigs + other changes
API /addresses/{address} now returns lastReference taking unconfirmed into account.

Added DELETE /peers/known to remove all known peers from repository.

Added blockchain locking around Transaction methods like isValidUnconfirmed
as they (temporarily) update account lastReference.

Ditto getInvalidTransactions, etc.

d1c547f24a Refactor to use BouncyCastle Ed25519/X25519, and more...
Remove old whispersystems, etc. *25519 and use new v1.61 BouncyCastle.

Fix proxy forging private key derivation from X25519 shared secret.
Also include Javascript test version for comparison.

Fix block rewards for proxy forging.

Add extra useful info to API call GET /admin/forgingaccounts.
Fix API response to POST/DELETE /admin/forgingaccounts when
passed invalid private keys.

Added block rewards and account flags to testchain config.

Tests to cover changes above.

00656f6724 Interim safety commit due to large number of changes!
log4j2.properties now has debugging entries removed.
log4j2-test.properties (not in repo) takes priority
 so using that in development instead.

Unconfirmed transactions no longer wiped on start-up
 by default - see Settings

Reworking of {Public,Private,Genesis}Accounts as it seemed
 possible to silently lose public key in repository.
The use of AccountData didn't work and so field-specific
 repository calls have been made instead
 (e.g. setLastReference) that try to opportunistically
 store public key too, if available (i.e. caller is
 PublicKeyAccount subclass, or better).

Added API call GET /addresses/{address} to return
 general account info in one go. (Essentially the
 AccountData object as fetched from repository).

Initial work on adding default groupID to accounts,
 along with corresponding SET_GROUP transaction type.
In additional, added blockchain-wide default groupID
 and flag to allow/disallow no-group/groupless
 transactions.

Initial work on group-admin approval of transactions
 tied to a specific group via txGroupId.

More work needed on transaction's "effective txGroupId"!

API call /transactions/pending to list transactions
 pending group-admin approval. However, this needs more
 work (see effective txGroupId above) and potentially
 offloading to HSQLDB repository if possible.

Minor CIYAM AT renames to help static reflection initializers.

Block.orphan() no longer adds orphaned transactions back to
 unconfirmed pile as they are themselves deleted during
 Transaction.orphan(). Maybe the answer is to NOT delete
 them during Transaction.orphan() but to add them to
 unconfirmed pile at that point? Very old transactions
 leftover from major resync would simply expire, whereas
 recently transactions leftover from minor resync could
 still make it into a new block on synced chain fork.

Changes/tidying/improvements to block generator regarding
 removing invalid transactions and dealing with transactions
 pending group approval.

Approval threshold added to groups.

Mass refactoring of transaction-related classes to unify
 constructors, particularly field ordering, to fall in line
 with raw transaction layout.
e.g. constructors now reflect that raw transactions mostly
 start with type, timestamp, txGroupId, publicKey, reference
e.g. JAXB afterUnmarshal methods added where needed and corresponding
 nasty code in Transaction subclass constructors ripped out.
e.g. TransactionTransformer subclasses contain less duplicated code.

Fixed bug with repository save points thanks to swapping to Deque.

Some fixes to do with missing transaction types being passed to JAXB
 TransactionData subclass constructors.

Ripped out obsolete toJSON in TransactionTransformers as this
 is all nicely taken care of by Swagger/OpenAPI (thanks @Kc)
