If we're to receive some 500 headers (less than `headerBatchCount`) and quit
before receiving more of them we end up with clean `bc.headerList` that will
be inited going backwards to the `targetHash`, but code path doesn't add add
the `targetHash` itself which it should do in this particular case, otherwise
we end with no genesis block hash in the list.
Missing it the following line could fail on subsequent restarts:
currHeaderHeight, currHeaderHash, err := storage.CurrentHeaderHeight(bc.store)
if the node was stopped before any headers had been received.
Extend Blockchainer with one more method to spawn a VM for test runs and use
it to run scripts. Gas consumption is not counted or limited in any way at the
moment (see #424).
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.
