Move functions for generating transactions into OnLedgerAsset from various locations in
the code (VaultService, AbstractConserveAmount, etc.) to unify the code paths and reduce
duplication.
* Remove progress Observable from FlowHandle, unless explicitly requested.
* Refactor FlowHandle creation into FlowStateMachine.
* Prevent server-side queue subscription for dummy Observable.
* Refactor so that RPC client does not receive any unused progress Observables. This is the simplest way of ensuring we have no dangling "hot" Observables when the RPC client closes.
* Test flow has correct handle.
* Resolve some compiler warnings.
* Document how starting a flow does not involve progress tracking by default.
* Update changelog and release notes for RPC API.
* Rename new RPC API to startTrackedFlow().
* Remove optimisation because of its affect on the client-side.
* Update documentation.
This introduces new functions for fetching parties by their X.500 name, Kryo serialization support for X500Name objects, an X500Name generator and some X509 utility support in preparation for full X.500 name support.
Add CompositeSignature and CompositeSignatureWithKeys classes as part of preliminary work to make CompositeKey signature validation compatible with java.security classes, so that these keys and signatures can be used readily in X.509 certificates.
Standaridise the identity names of Alice, Bob and Charlie, notary, map service, etc. in order
to ensure consistency across the code base and reduce number of places that have to be changed
to introduce proper X.500 names.
Move Alice, Bob & Charlie identities into the utilities package so they can be used in demos
* Make CompositeKey implement PublicKey
The initial implementation of composite keys as their own distinct class separate from PublicKey
means that the keys cannot be used on standard classes such as Certificate. This work is a beginning
to modifying CompositeKey to being a PublicKey implementation, although significant further work
is required to integrate this properly with the standard Java APIs, especially around verifying
signatures using the new key type.
* First stage of making CompositeKey implement PublicKey interface. Revert to using PublicKey everywhere we expect a key.
* Move algorithm and format into companion object (#432)
Move algorithm and format into companion object so that they can be referenced from other
classes (i.e. the upcoming signature class).
* Add simple invariants to construction of CompositeKey.
Builder emits CompositeKeys in simplified normalised form. Forbid keys with single child node, force ordering on children and forbid duplicates on the same level. It's not full semantical normalisation.
* Make constructor of CompositeKey private, move NodeWeight inside the class.
Add utility function for Kryo deserialization to read list with length constraints.
* Fixed bug whereby Cash Exit was not taking into account the issuer reference.
Added additional JUnit tests for coin selection by issuer.
Added some trace logging in AbstractConserveAmount.
* PR review: added additional state with 3rd issuer reference in test.
Clarify exceptions thrown from loading a key store as a general cleanup. Also tightens the
exceptions caught when loading key stores from AbstractNode, so in case of an unexpected error
we don't silently drop the exception.
Observable.subscribe().unsubscribe() dance to free up the MQ resources server-side.
* remove an unused import
* implement a FlowHandle<Transaction>.finalize method

Improved trace logging for coin selection (SQL row level info).
Correctly calling FlowStateMachineImpl sleep (now inlined and working correctly)
Fixed rebase error.
Remove redundant TODO message.
Add utility functions for requesting transaction keys and a small example flow which uses
these functions for testing purposes. These keys are required in for the anonymisation of
transactions, by providing per-transaction keys which cannot be associated with the owning
party's keys without an intermediary certificate.

* We were leaving trailing attachmentStorage on pooled kryo instances after some tests. Changed attachment storage logic to make it impossible to leave it behind.
* Some low level tests corrupt the Kryo config, so do not return to pool when this is the case. Also, we discovered that Kryo is caching class name to class resolution. We don't want to do this where attachments are involved. The errors raised highlighted a class missing from the whitelist. Need to write a unit test to test the class loader issue.
* Unit test for attachment class loading with kryo.
Convert NodeVaultService states to return Iterable (backed by Sequence) Vs the old way using a List. Worth noting this relieves memory pressure as the number of vault states grows.
* remove toList in ContractUpgradeFlowTest
Basic crypto API to support 5 signature schemes and MetaData-ed signatures.
Supported schemes: (1) RSA_SHA256, (2) ECDSA_SECP256K1_SHA256, (3) ECDSA_SECP256R1_SHA256, (4) EDDSA_ED25519_SHA512, (5) SPHINCS-256_SHA512.
To sign a transaction, a signer should create a MetaData wrapper that contains transaction's merkle root and some extra information, such as signer's public key, timestamp and visibleInputs. Actually, MetaData is utilised to support a practical partial, blind and extra-data attached signature model.
When a MetaData object is signed, the signer sends a TransactionSignature object that contains the signed output and the corresponding MetaData object.
Remarks:
This is an temporary solution for signature algorithmic agility. Further development is required for a robust and extensible Crypto Manager/Provider PKI that will support certificate creation, key generation, signing/verifying, deterministic key derivation, encoding formats, SGX/HSM support, identity and key management, versioning, revocation, asynchronicity, metadata, partial sig. policies etc.
* BFT notary prototype: add a non-validating service.
Each replica now validates the transaction timestamp and returns an individual signature to the BFT client. The client then returns a list of signatures back to the notary service flow.
The validating variant is still incomplete - it requires the ability to suspend flows on arbitrary function calls.
* Exclude old version of Javassist in favour of Hibernate's version.
* Comment why we are excluding javassist:javassist, and add TODO for when junit-quickcheck 0.8 is released.
Make notary flow return a collection of signatures to support the BFT notary. For a single-node or RAFT notary it would just contain a single signature.
* Initial prototyping with Requery as a persistence replacement for Exposed/Hibernate
Applied changes following PR review by RP
Updated timestamp naming (removed committedTimestamp) and StateStatus (removed AWAITING_CONSENSUS) after discussion with RP.
Removed FungibleState and LinearState schemas (and associated tests) - awaiting Requery uni-directional relationship fix.
Added Transaction propagation such that requery re-uses any existing transaction context.
Made requery default logging configurable (disabled by default)
Nullable fields are now truly nullable (in the Kotlin and DDL sense)
Fix for SimmValuation integration test.
Workarounds applied to resolve Requery issues when sharing Transactional context.
Addressed PR review comments from MH.

Add AnonymousParty superclass of Party in preparation for anonymising parties stored in
contract states.

Replaces the legacy name-only comparison in the vault service with a party comparison. `Party` now
has an equals method that only uses the owning key, and therefore this functions as expected.
Make FinalityFlow do more, and be used more consistently.
Add a new waitForLedgerCommit API that is intended to be used at the end of flows, or at any other point where a flow wants to wait for a transaction to finalise (but the finalisation flow is being done by someone else).
Update the docs a bit.
* Move merkle building extension functions on wire tx to WireTransaction class.
* Add timestamp, notary, transaction type and signers to wire transaction id calculation.
* Change construction of MerkleTree from duplicating last node on a given level to padding leaves' list with zero hash to size of the nearest power of 2 - so we always have a full binary tree.
The problem was that it was possible to construct 2 different transactions with the same ids. Trick worked for txs having number of leaves that were not power of 2.
* Update tear-offs documentation and diagrams to reflect changes in construction of Merkle trees - padding with zero hashes and including all WireTransaction fields in id computation.
* Change in filtering API of WireTransaction for partial Merkle trees calculation.
Instead of many filtering functions over a transaction only one needs to be provided.
Additional change to check and verification of FilteredTransaction.
* IRS demo change. Make filtering function a protected method of RatesFixFlow class.
Comment on situation when capturing too much scope and connected problems with checkpointing.
Change oracle and tear-offs documentation.
InMemoryNetworkMapCacheTest was not actually asserting that an expected exception was thrown, which
meant when earlier changes to the service changed the operation it wasn't caught. The service now
overwrites previous node if a new matching node is added, and this updates the test to follow that
design.
Change Party instances to be uniquely identified by the owning key, without taking into account name.
This requires that mock node key generation is reworked so that keys for services and the node itself
are distinct, otherwise the network map service cannot differentiate them.

This deprecates the existing composition clauses and adds new better named versions,
as well as changing 'AnyOf' to require at least one matching subclase (better matching
the name of the clause).
Add new functions for converting amounts to/from decimal representation. Also adds clarification that
the constructor which takes in a BigDecimal drops any fractional part.
