4a9ff84fc7 Allowing multiple signature algorithms (#250)
Basic crypto API to support 5 signature schemes and MetaData-ed signatures.
Supported schemes: (1) RSA_SHA256, (2) ECDSA_SECP256K1_SHA256, (3) ECDSA_SECP256R1_SHA256, (4) EDDSA_ED25519_SHA512, (5) SPHINCS-256_SHA512.

To sign a transaction, a signer should create a MetaData wrapper that contains transaction's merkle root and some extra information, such as signer's public key, timestamp and visibleInputs. Actually, MetaData is utilised to support a practical partial, blind and extra-data attached signature model.
When a MetaData object is signed, the signer sends a TransactionSignature object that contains the signed output and the corresponding MetaData object.

Remarks: 
This is an temporary solution for signature algorithmic agility. Further development is required for a robust and extensible Crypto Manager/Provider PKI that will support certificate creation, key generation, signing/verifying, deterministic key derivation, encoding formats, SGX/HSM support, identity and key management, versioning, revocation, asynchronicity, metadata, partial sig. policies etc.

907a893ca1 BFT notary prototype: add validation and signature collection (#279)
* BFT notary prototype: add a non-validating service.
Each replica now validates the transaction timestamp and returns an individual signature to the BFT client. The client then returns a list of signatures back to the notary service flow.

The validating variant is still incomplete - it requires the ability to suspend flows on arbitrary function calls.

45d8e0f76d Tearoff fixes (#78)
* Move merkle building extension functions on wire tx to WireTransaction class.

* Add timestamp, notary, transaction type and signers to wire transaction id calculation.

* Change construction of MerkleTree from duplicating last node on a given level to padding leaves' list with zero hash to size of the nearest power of 2 - so we always have a full binary tree.
The problem was that it was possible to construct 2 different transactions with the same ids. Trick worked for txs having number of leaves that were not power of 2.

* Update tear-offs documentation and diagrams to reflect changes in construction of Merkle trees - padding with zero hashes and including all WireTransaction fields in id computation.

* Change in filtering API of WireTransaction for partial Merkle trees calculation.
Instead of many filtering functions over a transaction only one needs to be provided.
Additional change to check and verification of FilteredTransaction.

* IRS demo change. Make filtering function a protected method of RatesFixFlow class.
Comment on situation when capturing too much scope and connected problems with checkpointing.
Change oracle and tear-offs documentation.

bc9407d2c8 Correct network map cache tests

design.

7cb4cbcad4 Made vault updates contain full StateAndRef in the consumed set (instead of just StateRef). This allows subscribers to check whether the update contains relevant states.
Cash balances are now calculated by keeping only the aggregate values (it no longer needs to iterate through all states in the vault).
