a6610ba082 core: verify blocks, fix #12
This adds the following verifications:
 * merkleroot check
 * index check
 * timestamp check
 * witnesses verification

VerifyWitnesses is also renamed to verifyTxWitnesses here to not confuse it
with verifyBlockWitnesse and to hide it from external access (no users at the
moment).

03c20f1876 core: make ContractState receiver names consistent
Linter isn't happy with our recent changes:

pkg/core/contract_state.go:109:1: receiver name cs should be consistent with previous receiver name a for ContractState
pkg/core/contract_state.go:114:1: receiver name cs should be consistent with previous receiver name a for ContractState
pkg/core/contract_state.go:119:1: receiver name cs should be consistent with previous receiver name a for ContractState

But actually `a` here most probably is a copy-paste from AssetState methods,
so fit the old code to match the new one.

238c590ddb core: fix contract state's Properties to use PropertyState
PublishTX only had one of these flags, but newer contracts (created via the
interop function) can have more and these flags are aggregated into one field
that uses PropertyState enumeration (it's used to publish contract, so
supposedly it's also a nice choice for contract state storage).

1bf232ad50 vm: introduce TryBool() for Element and use it in VerifyWitnesses
Script can return non-bool results that can still be converted to bool
according to the usual VM rules. Unfortunately Bool() panics if this
conversion fails which is OK for things done in vm.execute(), but certainly
not for VerifyWitnesses(), thus there is a need for TryBool() that will just
return an error in this case.

920d7c610c core: remove blockCache, use MemoryStore, redesign persist()
Commit 578ac414d4 was wrong in that it saved
only a part of the block, so depending on how you use blockchain, you may
still see that the block was not really processed properly. To really fix it
this commit introduces intermediate storage layer in form of memStore, which
actually is a MemoryStore that supports full Store API (thus easily fitting
into the existing code) and one extension that allows it to flush its data to
some other Store.

It also changes AddBlock() semantics in that it only accepts now successive
blocks, but when it does it guarantees that they're properly added into the
Blockchain and can be referred to in any way. Pending block queing is now
moved into the server (see 8c0c055ac657813fe3ed10257bce199e9527d5ed).

So the only thing done with persist() now is just a move from memStore to
Store which probably should've always been the case (notice also that
previously headers and some other metadata was written into the Store
bypassing caching/batching mechanism thus leading to some inefficiency).

578ac414d4 core: make unpersisted blocks/txs available in Blockchain
This changes the Blockchain to also return unpersisted (theoretically, verified
in the AddBlock!) blocks and transactions, making Add/Get interfaces
symmetrical. It allows to turn Persist into internal method again and makes it
possible to enable transaction check in GetBlock(), thus fixing #366.

ac5d2f94d3 storage: fix BoltDB batched Put()
It must copy both the value and the key because they can be reused for other
purposes between Put() and PutBatch(). This actually happens with values in

Extend the batch test to check for that.

100fee164b unitTest: reworked RPC unit test
earlier we had an issue with failing test in #353 and other one #305.
Reworked these test to have in-memory database. This led to multiple
changes: made some functions like Hash and Persist public(otherwise
it's not possible to control state of the blockchain); removed
unit_tests storage package which was used mainly for leveldb in unit
tests.
I see these tests not really good since they look like e2e tests and
as for me should be run in separate step against dockerized env or
in case we want to check rpc handler we might want to rework it in order
to have interface for proper unit tests.
As for me this patchset at least makes as safe with not removing totally
previous tests and at the same time CircleCI will be happy now.

b77e533d13 crypto/wallet: move public/private key into the new keys package
And drop associated _pkg.dev remnants (refs. #307).

Original `dev` branch had two separate packages for public and private keys,
but those are so intertwined (`TestHelper` subpackage is a proof) that it's
better unite them and all associated code (like WIF and NEP-2) in one
package. This patch also:
 * creates internal `keytestcases` package to share things with wallet (maybe
   it'll be changed in some future)
 * ports some tests from `dev`
 * ports Verify() method for public key from `dev`
 * expands TestPrivateKey() with public key check

ec7e17ffa6 pkg: make use of the new crypto/hash package
Simplifies a lot of code and removes some duplication. Unfortunately I had to
move test_util random functions in same commit to avoid cycle
dependencies. One of these random functions was also used in core/transaction
testing, to simplify things I've just dropped it there and used a static
string (which is nice to have for a test anyway).

There is still sha256 left in wallet (but it needs to pass Hash structure into
the signing function).

19201dcf52 Implemented rpc server method GetRawTransaction (#135)
* Added utility function GetVarSize

* 1) Added Size method: this implied that Fixed8 implements now the serializable interface. 2) Added few arithmetic operation (Add, Sub, div): this will be used to calculated networkfeeand feePerByte. Changed return value of the Value() method to int instead of int64. Modified fixed8_test accordingly.

* Implemented Size or MarshalJSON method.
- Structs accepting the Size method implement the serializable interface.
- Structs accepting the MarshalJSON method implements the customized json marshaller interface.

* Added fee calculation

* Implemented rcp server method GetRawTransaction

* Updated Tests

* Fixed:
1) NewFixed8 will accept as input int64
2) race condition affecting configDeafault, blockchainDefault

* Simplified Size calculation

* 1) Removed global variable blockchainDefault, configDefault
2) Extended Blockchainer interface to include the methods: References, FeePerByte, SystemFee, NetworkFee
3) Deleted fee_test.go, fee.go. Moved corresponding methods to blockchain_test.go and blockchain.go respectively
4) Amended tx_raw_output.go

* Simplified GetVarSize Method

* Replaced ValueAtAndType with ValueWithType

* Cosmetic changes + Added test case getrawtransaction_7

* Clean up Print statement

* Filled up keys

* Aligned verbose logic with the C#-neo implementation

* Implemented @Kim requests
Refactor server_test.go

* Small fixes

* Fixed verbose logic

1360e1de68 Added rpc unit tests (#107)
* Fixed small incosistencies related to comments and variable name

* For testing purposes we have to move the method newBlockchain from the cli/server/server.go to  pkg/core/blockchain.go. In addition we have to rename it to NewBlockchainLevelDB in order to be able to export it and avoid naming conflicts. In future we still need to think how to switch between different blockchain implementation easily but for the time being this is not possible.

* Added unit tests for the rpc server

* Added unit_testnet chain fixture

* fixed port number

* Added errors handling
