Preparation for getting rid of services + supporting multiple identities
on the node.
NodeInfo keeps multiple identities as a list. For now the first one is treated as a special one.
Introduced function chooseIdentity in CoreTestUtils as a preparation for proper handling of multiple identities in the future.
Remove legalIdentityKey from ServiceHub, add extension function - chooseIdentity on ServiceHub.
Add `me` field on FlowStateMachineImplemetation, flows should know what the calling identity is.

Apply Patrick's patch.
* ContractState's contract type has been moved to TransactionState and is now a string representing the class name of the contract class to allow classloading of arbitrary contracts from custom classloaders.
* Upgraded isolated JAR to new version.
* Enabled confidential identities in:
** IssuerFlow
** Trader demo
** Two party deal flows
** Two party trade flows
** Corda RPC tests
** Cash flows
** Integration testing tutorial
** Node monitor model tests
** CollectSignatureFlow
* Relay local node's confidential identities to counterparties when requesting transaction
signatures, so counterparties know where the inputs come from.

improve Java interop.
* Clean up Generator by moving extension functions into the class/companion class.
* Add documentation to the actual functions rather than being only on the top level class.
* Add JvmName to Generators
* Move extension functions into the classes they're used in to try supressing generation of empty RPCClientProxyHandlerKt class.
* Add JvmName to ConcurrencyUtils
* Move Iterable<ServiceInfo>.containsType() into Simulation, as it's only useful when verifying
setup of a simulated case. Resolves ServiceInfoKt class being generated.
* Move FlowHandle.notUsed() into the one place it's actually called, so Kotlin stops creating a FlowHandleKt class.
* Rename KeyFactory to CompositeKeyFactory
* Move expandedCompositeKeys into TestDSL as the only place that uses it
* Move NullKeys out of their own package

* Move utility classes out of crypto and into utilities package
Work on database backed NetworkMapCache
Make NodeInfo JPA entity.
Enable node startup with it's database network map cache. Fix schema.
Make node not wait for finishing network map service registration if it
successfully loaded data from database.
Add tests for startup without NetworkMapService.
* Rename networkMapRegistrationFuture
Change networkMapRegistrationFuture to nodeReadyFuture, it no longer
indicates the NetworkMapService registration, because we are able to run
network without map service configured.
* Partially integrate database into NetworkMapCache
Full integrtion will come with service removal.
Move MockServiceHubInternal to net.corda.node.testing
* Add workaround to transaction scope race
Temporary workaround to force isolated transaction (otherwise it causes race conditions when processing
network map registration on network map node).
* Remove WorldMapLocation from NodeInfo
Infer the node's location based on X500 name
Add serial number on NodeInfo
For tests of running without NetworkMap, start nodes with nonexistent NetworkMap address
Make clearNetworkMapCache callable via RPC.
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.
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
Update to use LedgerTransaction api
Push query output logic onto BaseTransaction and update usages where possible
Migrate a few more uses
Address some PR comments
Address some PR comments
Fixup after rebase
* 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
* 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.
* Fix wrong layout of new added nodes to map view in explorer. Fix double rendering of myIdentity label.
* Make buttons in map view take the whole available space.
* Remove party full name from network map view in explorer.
* Fix bug in demobench. Explorer didn't show correctly location of a node.
There was no nearestCity override in config.
* Remove nearestCity from node configuration. Now information about the location is always taken from
node's legal name. If not present - exception on node startup.
* Add X500Name.locationOrNull that soft fails when location is not in X500 name. Address PR comments.
* Remove unused imports.
* 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.
Switch to using AbstractParty as the standard identifier for parties in
states, so that full parties can be used during construction of
transactions and anonymised parties when the transaction is being added
to the ledger.
Move AbstractParty, AnonymousParty and Party into a new net.corda.core.identity package,
as they're not really cryptography tools, and in preparation for further code coming in
for identity.
Optimize imports on many files to clean up the resulting refactor.
Change the legal name of parties to be an X500 name. This ensures that we aren't converting between
common names and X500 names in various places, eliminating substantial scope for error in the conversion
process. As a result, all node names must now be full X500 names, which has impact on most configurations.
Clean up X500 names in Corda simulation, and ensure they're consistent with the standard test names.
This includes using the locations present in those test names, which requires updates to the node
config test.
This is an intermediary step to introducing X500Names in all Party instances, which adds:
* Party constructor which accepts X500Name and then converts it to string.
* startNode() function which takes in X500Name instead of String
* Numerous legal name fixes to use full distinguished names
* 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.
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.
Observable.subscribe().unsubscribe() dance to free up the MQ resources server-side.
* remove an unused import
* implement a FlowHandle<Transaction>.finalize method
* Rename finalize() to discard() - remove the collection and run discard individually
* Remove unused imports
* Observable.notUsed helper function
* Tweaks to comments
* FlowHandle implements AutoClosable
* Resolving conflicts and move notUsed to RPC module
* Copy Observable.notUsed in core module.
* delete discard method
Add an AmountTransfer type to express the concept of asset flows.

Improved logging, changed to StateNotAvailableException, using Flow sleep upon retry, tweaked SELECT criteria in coin selection, fixed bug when insufficient states selectable, generateSpend is now @suspendable
Improved handling and logging of flow results in Simulation Mode.
