5c65d33439 native: move required balance check to token contracts
Which duplicates the check, but deduplicates error path. This check forced
double balance deserialization which is quite costly operation, so we better
do it once.

It's hardly noticeable as of TPS metrics though, maybe some 1-2%%.

e8bed184d5 core: implement dynamic NEP17 balances tracking
Request NEP17 balances from a set of NEP17 contracts instead of getting
them from storage. LastUpdatedBlock tracking remains untouched, because
there's no way to retrieve it dynamically.

aab18c3083 stackitem: introduce Convertible interface
We have a lot of native contract types that are converted to stack items
before serialization, then deserialized as stack items and converted back to
regular structures. stackitem.Convertible allows to remove a lot of repetitive
io.Serializable code.

This also introduces to/from converter in testserdes which unfortunately
required to change util tests to avoid circular references.

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()`.

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.

58ab3b5ad1 core: get native nep17 balance from contract storage
Not from DAO's items with storage.STNEP17Balances prefix, because
changes are reflected there only after notifications processing. And
this happens only after the transaction script is executed, but there
might be cases when we need to get the balance that was updated
earlier during the same transaction processing.

Affects storage dumps.

b7194ec608 core: put candidate account to the storage during (*NEO).vote
C# node uses Snapshot.GetAndChange to get it from storage, so it's the
same problem as with voting account. Affects dumps.

c63528db44 core: put voiting account to the storage during (*NEO).vote
After getting account from the storage there are a lot of checks which
may fail. But C# node uses Snapshot.GetAndChange, so the account state
should be put in the storage even in case of vote failure. Affects
dumps.

3d8d927178 core: check candidate is registered at the start of voiting
C# node returns an error if the candidate is not registered. We have this
check inside the ModifyAccountVotes, but (*NEO).vote doesn't panics and
just return bool on stack, so we should match exactly the C#'s
algorithm.

ac527650eb native: add Ledger contract, fix #1696
But don't change the way we process/store transactions and blocks. Effectively
it's just an interface for smart contracts that replaces old syscalls.

Transaction definition is moved temporarily to runtime package and Block
definition is removed (till we solve #1691 properly).

2fee69f26f core: add missing onPersist and postPersist methods to natives
Although not every contract is persisted (see
https://github.com/neo-project/neo/blob/master/src/neo/Ledger/Blockchain.cs#L94)
we have to add `onPersist` and `postPersist` methods to every
native contract in order to display them in manifest for users and
follow C# behaviour. In C# there are `onPersist` and `postPersist`
methods in base native contract class, see
https://github.com/neo-project/neo/blob/master/src/neo/SmartContract/Native/NativeContract.cs#L141
and
