A user passed in a `FlowLogic` as an argument into another `FlowLogic`
called `subFlow` on it and had it throw an exception.
This all occurred before the first checkpoint, causing the state machine
to try and persist a FAILED checkpoint containing the flow's arguments.
Because the arguments contained a `FlowLogic` that had been started via
`subFlow` it held a reference to `FlowLogic._stateMachine` which cannot
be serialized.
This caused the flow to fail when trying to persist the fact that it
failed.
The flow arguments are now emptied during `ErrorFlowTransition` to
resolve this issue which mimics the behaviour of the first suspend.
Note, this only takes the arguments out of the serialized checkpoint, it
does not affect the flow metadata and therefore a flow's arguments can
still be viewed.

Prevent some serialization errors that occur due to serialization
and deserialization of `ArrayList$SubList` found inside the
`SessionState` data structures.
To prevent this, an explicit `ArrayList` is used rather than a `List`.
Overload the `List` operator functions so that `+` returns an
`ArrayList` instead of a `List`.
Create `toArrayList` for a few conversions.
If a flow fails outside of its normal error processing code path it will
end up in `FlowDefaultUncaughtExceptionHandler`.
This handler will put the flow into overnight observation if possible.
This is done in-memory and the database.
Even with this being done, the fiber itself has blown up and therefore
does not manage to get to `SMM.removeFlow` which is where
`SMM.decrementLiveFibers` is called. For example, a flow that errored
will hit this code eventually. This code is also hit when a flow is
suspended and a shutdown event is sent to it.
The `liveFibers` latch blocks the SMM from shutting down until all flows
have finished or processed shutdown events.
The changes described below resolve this problem.
Any flow that goes to the `FlowDefaultUncaughtExceptionHandler` will be
put marked as dead (`StateMachineState.isDead`). Highlighting that the
flow cannot continue to process events normally as it has broken out
of its event loop
Retrying and shutdown are done manually rather than injecting events
into the flow fiber's queue, because it can't execute its event loop.
Killing a dead flow executes an altered version of
`retryFlowFromSafePoint`. It does this so it can delete the checkpoint
and then continue using the checkpoint it just deleted to run the
kill flow transition on a new fiber.
If a killed flow reaches the `FlowDefaultUncaughtExceptionHandler` it
will be forcibly killed via `killFlowForcibly` which deletes the
checkpoint/or updates it to KILLED and then calls `removeFlow` to bypass
any event processing. This means that a flow that was dead and was killed
will be terminated manually if it reaches the handler again. The same is
true for flows that were not dead before but reached the handler after
being killed.
Also, `FlowCreator.createFlowFromCheckpoint` now retains the `isKilled`
state of the previous fiber's state.

Direct SQL was causing issues with the saving of instants not
maintaining their timezones properly.
Changing to parameterised queries fixed this issue.
Also changed other queries to do the same, since it is good practice to
query in this way.
Change assertion in `Restart does not set senderUUID` to verify a single message has a sender UUID set, rather than the last to be recorded as sent has no sender UUID.

Do not let a user reattach to a flow started by another user.
Reattaching to a flow using startFlowWithClientId for a flow not
started by the current user throws a PermissionException
Reattaching to a flow using reattachFlowWithClientId for a flow not
started by the current user returns null.
finishedFlowsWithClientIds does not return flows started by other
users.
Normal rpc permissions around startFlowWithClientId and
startFlowDynamicWithClientId has also been added.
To allow admins to remove client ids as well as be able to see all the
client ids on the node, admin versions have been added that bypass the
user restrictions. These can be permitted via rpc to only provide
their usage to admins.

If a flow is started with a client id, do not delete it from the
database. Instead, set the status to `KILLED` and store a
`KilledFlowException` in the database.
Keeping it around allows it to be reattached to using the same
mechanisms as active, completed or failed flows. Furthermore, without
this change it could be possible for a flow to be triggered again if
killed while the reconnecting rpc client is being used.
If there is no client id related to the flow, then kill flow keeps its
original behaviour of deleting all traces of the flow.
Flows cannot be killed if they are `COMPLETED`, `FAILED` or `KILLED`
already.
Logs have been added if requests to kill flows in these statuses are
made.
Do not update the status + persist the exception if the flow was killed
during flow initialisation (before persisting its first checkpoint).
Remove the client id mapping if the flow was killed and did not persist
its original checkpoint.
* ENT-5666 Extract shutdown events when retrying a flow
When a flow is retrying, only a select set of events are transferred
over to the new fiber. Shutdown events were not included in this set.
This meant that if a flow retries when an `Event.SoftShutdown` is in its
queue, it will never process it. This causes the node to hang, as the
node awaits `liveFibers`, which never reaches 0 because the shutdown
event is never processed.
To resolve this, `Event.SoftShutdown` is added to the set of events to
extract and reschedule.
* ENT-5666 Don't schedule extra shutdown event
When a flow is stopped by an `Event.SoftShutdown` it will eventually
reschedule another shutdown even when it reaches `SMM.removeFlow`. It
won't actually be processed because the flow returns an abort
continuation. But, it does look odd.
Therefore, it now does nothing instead since that is what it was
implicitly doing.
Created a database snapshot of a clean Corda OS 4.5.1 database, which can now be used for testing by both the node driver and mock network.
The MockNetwork was changed from using an in memory database to using an on disk database, and makes use of the snapshot to speed up setup times.
The Node Driver was changed from defaulting to an in-memory database to defaulting to an on-disk database. Tests that do not specify the type of database to use will thus use an on-disk database. Tests that opt in for an in-memory database will continue to use an in-memory database as before.
The database snapshots are copied to the node directory inside the build folder, therefore, they should be cleaned up after a build.
