NewInvocationTX() returned a version number one transaction that actually
failed to pass that version down to the invocation data which lead to
serialization/deserialization inconsistency.
VM should be responsible for code execution and in case anyone interested in additional logging or errors they could handle them like we do it iin cli.
We're about stored values here, so print those, which avoids blocking in
bc.HeaderHeight() and removes duplication between blockHeight and
persistedHeight. Fixes saving the blockchain on exit (deferred function in
Run() blocked in persist()).
Test modification was required because storeBlocks() doesn't actually save
headers and thus TestGetTransaction started to fail on persist().
If you're to sync less than 2000 headers no batched header key-value is
gonna be written into the DB and init() would panic because
bc.headerList.Len() would return 0. Use genesis block as a target in this
case.

commit methods duplicated putSmthIntoStore functions, but have MemCachedStore
now that can easily substitute for a Batch, especially given that interop
needs something like that for its storage purposes anyway.
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).
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.
Enable transaction verification for privnets and tests, testnet can't
successfuly verify block number 316711 with it enabled and mainnet stops at
105829.
We want to get a full block, so it has to have transactions
inside. Unfortunately our tests were used to this wrong behavior and utilized
completely bogus transactions without data that couldn't be persisted, so fix
that also.
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).
It's used a lot and it looks a lot like MemoryStore, it just needs not to
return errors from Put and Delete, so make it use MemoryStore internally with
adjusted interface.
Make it look more like a real transaction, put/delete things with a single
lock. Make a copy of value in Put also, just for safety purposes, no one knows
how this value slice can be used after the Put.
Using pointers is just plain wrong here, because the batch can be updated with
newer values for the same keys.
Fixes Seek() to use HasPrefix also because this is the intended behavior.
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.
If the block references two ouputs in some other transaction the code failed
to verify it because of key collision. C# code implements it properly by using
full CoinReference type as a key, so let's do it in a similar fashion.
Claim transactions have different logic in C# node, so we need to
implement it too. It's not the most elegant way to fix it, but let's make it
work first and then refactor if and where needed. Fixes verification of Claim
transactions.
