This improves the Java API and makes it more idiomatic. The methods
were not moved to be static methods of the relevant types in all cases
due to a bad interaction with a Kotlin auto-completion bug, and because
static methods on interfaces are new in Java 8 and Kotlin is not yet
emitting Java 8 bytecode.
Also, introduce a packages.md file so packages can be documented.
* Removed notary_key (and all references) from vault schema.
Fixed incorrect NOTARY usage in certain tests (cash consumption)
* Fixed broken test.
* Replace CommonSchemaV1.Party in all VaultSchema tables (and associated queries) with string'ified X500Name's only.
* Fix broken tests.
* Completely remove CommonSchemaV1.Party and all references (in favour of X500Name's)
* Updated all schema attribute identity references to use AbstractParty.
* Updated all schema attribute identity references to use AbstractParty.
* Standarised attribute naming for parties (removed 'Name')
* Updated deprecate identity API references following rebase.
* Configurable IdentityService as a lambda in JUnit tests.
* Additional WARNING logging to enable troubleshooting of identity lookup failures.
* Final identity updates to sample schemas.
Cleaned up several compiler warnings.
Change CashIssueFlow to always issue to ourselves, and require the cash is then moved in a separate payment
operation. This more closely models actual operation inside banks, and is a step towards making all move-like
operations go through a uniform verification process.
* Remove IssuerFlow as it is dangerous and its presence in the finance module risks accidental use in non-test code. As written it will issue arbitary amounts of currency on request from any node on the network, with no validation barring that the currency type is valid.
* Unify interface to CashIssueFlow to match the previous IssuerFlow
*Remove dummy public keys in preference for EdDSA keys generated from fixed entropy sources, as a more accurate reflection of real uses. Also eliminates a serialization format issue with dummy keys which would have to be resolved otherwise.
* Remove deprecated 'by' keyword from contracts DSL
* Remove deprecated parts of CordaPluginRegistry
* Merge identity registration of well known and confidential identities
* Move verification logic into PartyAndCertificate from IdentityService

Address some PR comments
Fixup after rebase
* Registering anonymous identities now takes in AnonymisedIdentity
* AnonymousParty.toString() now uses toStringShort() to match other toString() functions
* Add verifyAnonymousIdentity() function to verify without storing an identity
* Replace pathForAnonymous() with anonymousFromKey() which matches actual use-cases better
* Add unit test for fetching the anonymous identity from a key
* Update verifyAnonymousIdentity() function signature to match registerAnonymousIdentity()
* Rename AnonymisedIdentity to AnonymousPartyAndPath
* Remove certificate from AnonymousPartyAndPath as it's not actually used.
* Rename registerAnonymousIdentity() to verifyAndRegisterAnonymousIdentity()
Remove `createTwoNodes()` from mock network as its behaviour is inconsistent with creating a set of nodes. `createSomeNodes()` is generally a better fit and creates a network map and notary, and registers all nodes. Where that's not the intention, it's acceptable to manually create each node.
* POMs generated by publishing are now correct. The publish extension now requires an explicit call to configure the publishing instead of waiting until after evaluation. This prevents evaluation order issues with the artifact renaming code that causes the POM to have the original, incorrect, artifact names.
* Fixed new test compile issues caused by removal of some dependencies in test utils that caused webserver code to be automatically included in any project also compiling test utils.
* Implemented Kryo custom serializers for Field and KProperty types.
* Adjusted KPropertySerializer to use kotlin member properties upon read() due to failing RPC tests.
Added additional Kotlin and Java tests (CordaRPCClient, StandaaloneCordaRPCClient)
Annotated schemas to be CordaSerializable (required when referencing as KProperty in custom queries).
Cleanup some outstanding compiler warnings.
* Added client RPC Java integration and smoke tests to build.
* Clean up compiler warnings in Java tests.
* Fixed incorrect assertion expectation.
* Backed out Field and KProperty custom serializers.
* Backed out Field and KProperty custom serializers.
* Store VaultQueryCustom custom column references as name and class (from Java Field and Kotlin KProperty1 types respectively).
Custom serialization of Field and KProperty type no longer required.
* Removed blank lines as per RP review comments.
* Change "for who" to "for whom"
* Don't pass parties to FinalityFlow, it can derive them automatically
* Create a basket of nodes instead of individually assembling nodes
* Switch two party trade flow tests to generate a full anonymous identity
* Switch to using anonymous party as recipient
* Enable anonymisation for issuance as well as move in issuer flows.
* Pass notary into issuer flow rather than taking a notary at random from the network map.
* Enable anonymisation in Bank of Corda RPC test
* Parameterize issuer flow tests into anonymous and deanonymised versions
Modify issuer flow test to verify the consumed/produced states, rather than just checking the transaction matches the value returned via the flow state machine. This is both a simpler and more relevant test.
* Identities returned from TxKeyFlow were backwards, meaning keys were incorrectly assigned to the remote and local identities. Added unit test covering this case and corrected the flow logic.
* Rename TxKeyFlow to TransactionKeyFlow
* Correct registration of transaction key flows
* Move TransactionKeyFlow.Provider into CoreFlowHandlers
* Move TransactionKeyFlow.Request up to the top level class instead of being a class within an object.
* Remove AbstractIdentityFlow and move the validation logic into individual flows to make it clearer that it's registering the received identities.
* Cash flows now return the recipient identity instead of full identity lookup, as this is what
the caller actually needs and simplifies a lot of cases.
* Add functions for:
* Retrieving nodes via their legal identity
* Filtering a set of public keys down to those the node has corresponding private keys for
* Modify contract upgrade flows to handle identifying participants after an anomymisation step
* Correct terminology: "party who" -> "party which"
* Modify CashIssueFlow and CashPaymentFlow to optionally use an anonymous identity for the recipient.
* First stage of changing fields in NodeInfo.
Part of work related to NetworkMapService upgrade. Create slots for
multiple IP addresses and legalIdentities per node.
* NodeInfo stores HostAndPort.
Move information specific to messaging layer away from NodeInfo.
Only HostAndPort addresses are stored. Add peer name - peer handle
mapping to MockNetwork to reflect that change.
* Vault Query Service API implementation using JPA Hibernate
Added queryBy(QueryCriteria) Vault API and Junit tests.

Added additional @CordaSerializable annotations.
Updated documentation and referenced sample code.
Added deprecation annotations.

Revisited and fixed usage of @CordaSerializable.
* Minor fix following rebase from master.
* Remove blank line as per RP PR feedback request.
* Minor Java documentation and example clean-up.
* Disable BFT Notary Service tests.
Modify generateExit to return full set of signing keys in preparation for anonymity work meaning
that owner and issuer keys are typically not the same.
All references to 'parties' now refer to the inherited 'participants' attribute from ContractState.
Samples: all duplicate references to `parties` now changed to `participants`.
Clean up cash tests ahead of anonymisation work. This simplifies some boiler plate setup/teardown
and ensures idenities and flows are correctly registered.
Core corda publications and JARs now have cord or corda at the start (excluding gradle plugins). Removed an unnecessary dependency on test-utils in node-schemas to prevent an evaluation order bug in gradle.
Change PartyAndCertificate to an aggregate class instead of a subclass of Party. This reduces the changes compared to M11, as well as avoiding risk of accidental serialization of a PartyAndCertificate (which may be very large) where a Party is expected.
Cleaned up initial nodes known to the identity service, in particular mock nodes now know about themselves; previously full nodes registered themselves but mock nodes did not.
* Construct standard flows using PartyAndCertificate, and add support for launching
flows that are constructed with PartyAndCertificate or just Party.
* Store PartyAndCertificate in network map service
* Expand identity service to store certificates along with all identities.
This removes the need to do manual registration using the PluginServiceHub. As a result CordaPluginRegistry.servicePlugins is no longer needed. For oracles and services there is a CorDappService annotation.
I've also fixed the InitiatingFlow annotation such that client flows can be customised (sub-typed) without it breaking the flow sessions.
* De-anonymise parties in AbstractStateReplacementFlow flows
* Convert transaction key negotiation to a subflow instead of utility functions
* Add serialization support for CertPath
* Restructure cash flows so that a counterparty flow can be added later
Remove mock identity service and merge it with the in memory identity service. The two services
provide extremely similar functionality, and having two different version for production/test
risks subtle implementation differences. On that note, this patch includes changes to a number
of tests which worked only with mock identity service.
