NotaryFlow.Client flow assumes the passed transaction is verified, which is
the case when it's invoked as a sub-flow in FinalityFlow. However,
NotaryFlow.Client can also be called directly from any custom flow, so
we need to ensure it performs transaction verification to avoid accidentally
sending an invalid transaction to a non-validating notary.

Updating FinalityFlow with functionality to allow the initiator to indicate the appropriate StatesToRecord. This allows the initiating party to record states in transactions which they are proposing but are not necessarily participants of.

This proposal is a little more flexible by design. It adds a property to the state pointer class, allowing them to be referenced in transactions on a per-state-pointer basis.
* CORDA-3133

- Moved `isResolved` out of the constructor into an abstract property.
- Added deprecation constructor declaration for backwards compatibility.

* CORDA-3133 (version 2)
- fixed unit tests.
- added comment to changelog.rst.
- added helper functions to `StatePointer` to allow easier creation of static and linear pointers.
Allow node operators to blacklist signing keys (using blacklistedAttachmentSigningKeys config option). These blacklisted keys prevent attachments that are received over the network from being trusted. The docs have been updated to detail how to generate the key hashes that the config requires.
A new shell command attachments trustRoots has been added to see what attachments exist on the node along with information about their trust and where it comes from.
run dumpCheckpoints has been replaced by checkpoints dump as InternalCordaRPCOps needed to change to prevent a function that is meant to be internal from being visible on the shell.

* CORDA-3018 Allow loading an untrusted contract jar if another attachment exists that was signed with the same keys and uploaded by a trusted uploader
`TransactionUtils.isAttachmentTrusted` requirements have been relaxed
to allow an untrusted attachment to be loaded as long as another
attachment exists that is signed by the same keys and was uploaded
by a trusted uploader.
The requirement of containing the same contract classes has been
removed. Therefore the contents of the existing trusted attachment
no longer matters.
* CORDA-3018 Allow a subset/intersection of signers in `isAttachmentTrusted`
Allow a subset/intersection of signers to satisfy the signer
requirements of `isAttachmentTrusted`. This allows an "untrusted"
attachment that is signed by one or more keys to be "trusted" as long
as another trusted attachment already exists that is signed by at least
one of the "untrusted" attachments signers.
A cache of trusted and untrusted public keys is now held (replacing the
previous cache of `List<PublicKey>`.
Tests have been added to `NodeAttachmentServiceTest` to confirm that
an attachment query using an `EQUAL` statement will actually return
attachments that are signed by any of the keys passed into the query.
Confirming this allowed an `EQUAL` query to satisfy the search that
had to be done as part of this change.
`MockAttachmentStorage`'s query criteria was updated to better match
the real `NodeAttachmentService` implementation.
* CORDA-3018 Update cache name and kdoc on `isAttachmentTrusted`
* CORDA-3018 Verify that chains of trust do not occur
* CORDA-3018 Switch keys around to improve chain of trust tests
* [ENT-3801] Store transactions in the database during transaction resolution (#2305)
* ENT-3801: Store downloaded txns as part of the backchain resolution into the db rather than the checkpoint
It's very inefficient to store the downloaded backchain in the checkpoint as more of it downloaded. Instead, if a threshold is reached (which currently defaults at 0) then the backchain is stored in the transactions table as unverified. A new is_verified column has been added to track this. Initially testing on the OS codebase has been very promising but unfortunately this current code is not quite ready. I had to quickly port it to ENT as this is meant to be an ENT-only optimisation.
To that effect, there is a TransactionResolver abstraction with two implementations: an in-memory one which has the old behaviour, and which will be the behaviour for OS, and a db one.
DBTransactionStorage hasn't been fully updated and I had to comment out the optimistic path for now.
Most of these changes will need to be ported to OS to keep the merge conflicts in check, but obviously not DbTransactionsResolver and the "is_verified" changes in DBTransactionStorage. DBTransactionStorage does have other refactoring which will make sense to port though.

Allow Hash Constraints to propagate to Signature Constraints. When
propagating, the new jar is added to the transaction instead of the
original contract attachment (jar).
The following requirements must be met to do so:
- System property "net.corda.node.disableHashConstraints" must be set
to `true`
- The min platform version must be 4 or greater
- There must be an input state with a hash constraint
- There must be no output states with a hash constraint
- The new jar must be signed
If these requirements are not met, the original Hash
Constraint will be kept and the contract attachment related to it is
also used.
This transition is done at the start of `handleContract` as it is not
the normal path a transition would follow. It is considered a backdoor
and should be treated separately from the rest of the attachment and
constraint logic. Furthermore, it will only work in private network
since all nodes must set the special `disableHashConstraints` flag.
As a general purpose API, allPersisted should not be loading the entire contents of the database table into memory. Instead now it returns a Stream for processing of elements.

Dumps all the node's checkpoints as JSON into a single zip file in the node's directory. The output contains:
* All the fields for the top-level flow
* The current sub-flow call stack, along with the current progress tracker step for each sub-flow
* The event that suspended the flow, which if it's a send or sendAndReceive will show the payload that was sent
* Low level information on the active sessions with other peers
Party and AnonymousParty have been retrofitted to implement this interface and are currently the only supported types. A new FlowLogic.initiateFlow(Destination) method overload to easily support the addition of new destination types in future versions.
To prevent making `dumpCheckpoints` part of the public API a new
interface, `InternalCordaRPCOps` has been created and the function
has been moved there. `InternalCordaRPCOps` inherits from
`CordaRPCOps`.
`CordaRPCOpsImpl` now implements `InternalCordaRPCOps`.
`RunShellCommand` and `StringToMethodCallParser` required additional
changes due to issues handling inherited functions. This has only been
raised now due to `InternalCordaRPCOps` inheriting from `CordaRPCOps`.
Many classes have had references to `CordaRPCOps` changed to
`InternalCordaRPCOps`.

This allows a different signed version of the same CorDapp to be automatically trusted.
This reverts "[CORDA-2575] Allow users to whitelist attachments by public key config (#5035)"
The Signature Constraint documentation in `api-contract-constraints`
was very limited and referred to the design doc for most information.
Information was extracted from the design doc and added to the main
documentation.
If a single whitelisted constraint is being used by input states and the version of the cordapp changes + is signed, then the constraint will transition to a signature constraint.
When a `UnexpectedFlowEndException` or a `FlowException` is received the
peer that the exception was thrown from will be added to the stacktrace.
This is due to it being easier to see and a field that developers
are much less likely to override.
A nullable field `peer` has been added to `FlowException` and
`UnexpectedFlowEndException`. This is read later on (when peer info
is not available) to append the peer info to the stacktrace.

In Corda 4, FinalityFlow was updated to become an initiated flow, in order to ensure a node does not have to accept any signed transaction it receives without being able to check it first. The old behaviour of FinalityFlow was gated behind a targetPlatformVersion check, to prevent apps targeting V4 from using the old behaviour.
This is problematic for a few reasons. For an app wishing to be backwards compatible with a version running on V3, this forces the app to set targetPlatformVersion = 3, even if the app is thoroughly tested against V4. This goes against the purpose of the targetPlatformVersion. Another consequence is that an app remains pinned to targetPlatformVersion = 3 until it is sure that there are no other apps running at a lower version in the network, which would prevent newer versions of the app from taking advantage of features gated behind targetPlatformVersion checks. (Note that the restriction only prevents a new version of the app from initiating FinalityFlow with the old version - the old version is able to initiate a FinalityFlow and the new version will handle it, assuming the app has been written correctly.)
This fix removes the targetPlatformVersion check from FinalityFlow, and also provides a few documentation updates to clarify what level of testing would be expected to set a targetPlatformVersion.

With (Contract JARs) rolling upgrades the downgrade rule cannot be effectively check as the platform can't tell the difference between a transaction that's downgrading because of an attack, vs a transaction that's downgrading because Alice has upgraded but Bob hasn't yet. During a rolling upgrade we would expect state versions to fluctuate up and down as data gets read/written by a mix of nodes. With the feature as implemented Alice will upgrade and start trading with Bob. Bob will be able to read and process the states Alice sent him, but the moment he tries to consume such a state he will fail. This will result in cascading flow deaths and a hung business network the moment an upgrade starts.
