This moves a lot of the test support code into its own package which is only imported for tests,
so it's not shipped as a part of core Corda. The node currently depends on this support code to
compile, although future work could try to separate this out. This change highlights that parts
of production code is dependent on test elements (i.e. dummy keys), and makes it harder for
such accidental crosses to occur later.
An integration test category is also added as part of this work, to contribute towards COR-345.
Rework clauses so that rather than defining match/no-match behaviour themselves, they are
now composed by nesting them within clauses that understand how to match their child clauses.
This unifies a lot of the structure of clauses and removes corner cases needed for the first
design, as well as moving towards a model which is easier to prove.
Remove the ability to exit cash not held by the cash issuer; this solves a number of problems:
* Ensuring owner of the cash is aware of the funds being destroyed
* Determining where to send any change resulting from partial exiting of funds
* Auditing the destruction of funds

Changes include:
- LedgerTransaction is now much more central: it represents a fully resolved and looked-up tx, with the inputs available.
- TransactionGroup and TransactionForVerification are gone. There is a temporary TransactionForContract class for backwards
compatibility but it will also be gone soon.
- ResolveTransactionsProtocol is simplified, and now commits a tx to the database as soon as it's determined to be valid.
- ServiceHub is now passed in more consistently to verification code, so we can use more services in future more easily e.g. a sandboxing service.
- A variety of APIs have been tweaked or documented better.
The obligation `Settle` command takes in an amount to be settled, but only uses the underlying token from it.
This enforces that the settled amount matches the value seen moving.
- Move code out of ambiguously named TestUtils files (there were three). Sometimes it's simpler to just put these things into the contract source files directly.
- Remove JavaTestHelpers objects (there were three), in favour of just giving the top level kotlin file class better names.
- Misc other small tweaks and cleanups.
As the timestamping authority is now always the notary service, contracts should
no longer be using name-based lookup of the timestamping authority (as this will
generally be wrong). This introduces a new "timestamp" property on a transaction,
and updates most contracts to refer to it.
In some cases (IRS, CommercialPaper) there are transactions with no input states
to derive notary from, that use timestamps. In these cases a notary is specified
in the command.
This makes the error messages when verifying state issuance consistent between
Cash, CommercialPaper and Obligation contracts, in preparation for introducing
a common issue clause between the contracts.
