e62a766058 state: move nil check down to stackitem JSON processing 
We want to return real errors, not some generic thing for any kind of thing
happening.

0de949b575 stackitem: remove Item/StackItem from function names 
They're useless in a package named 'stackitem', make this package a bit more
user-friendly.

0591366f85 native: cache GAS per vote values 
`storage.Seek()` is rather expensive and we need only last updated value
of gas per block in `PostPersist()`.

9673a04009 core: allow to add several headers with StateRootInHeader on 
Problem: with StateRootInHeader setting on only one header of height N+1
can be added to the chain of height N, because we need local stateroot
to verify headers (which is calculated for the last stored block N).
Thus, adding chunk of headers starting from the current chain's heigh
is impossible and (*Blockchain).AddHeaders doesn't have much sense.

Solution: verify header.PrevStateRoot only for header N+1. Rest of the
headers should be added without PrevStateRoot verification.

d49294b046 core: fix the way candidates are sorted 
(*NEO).GetCandidates along with getCandidatesCall use candidates sorted
by serialized ECPoint bytes.

(*NEO).computeCommitteeMembers use candidates sorted by votes, and then
by deserialized ECPoint, i.e. using default ECPoint comparator.

be902afe9e core: do not allow NEP17 roundtrip in case of insufficient funds 
NEP17 roundtrip is prohibited if from account doesn't have enough funds.

This commit fixes states diff in block 92057 where account
NfuwpaQ1A2xaeVbxWe8FRtaRgaMa8yF3YM initiates two NEO roundtrips with
amount exceeding the account's balance:

by a contract ID. However in theory it can lead to a different
