5a42b5c7ae network: correct block addition check
Fixes missing an error on block addition when the header actually went it, but
the block didn't.

807338f97e core: do not store NEP5 transfer log in memory
Traversing transfer log instead of accumulating and returning it
is faster and takes less memory.

791c983304 core: drop GetScriptHashesForVerifying
It no longer depends on blockchain state and there can't ever be an error, in
fact we can always iterate over signers, so copying these hashes doesn't make
much sense at all as well as sorting arrays in verifyTxWitnesses (witnesses
order must match signers order).

0e2784cd2c always wrap errors when creating new ones with fmt.Errorf()
It doesn't really change anything in most of the cases, but it's a useful
habit anyway.

Fix #350.

5ef08f60ae remove github.com/pkg/errors from dependencies
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.

6c8accf18c core, network: request blocks instead of headers
Closes #1192

1. We now have CMDGetBlockByIndex, so there's no need to request headers
   first when we can just ask for blocks.
2. We don't ask for headers (i.e. we don't send CMDGetHeaders),
   consequently, we shouldn't react on CMDHeaders.
3. But we still keep on reacting on CMDGetHeaders command as
   there could be a node which needs headers.

chain is lower). Fixed. It also should return all requested blocks, not
the first one.

7eef895061 consensus: use GetNextBlockValidators where appropriate
GetValidators without parameter is called upon DBFT initialization and it
should receive validators for the next block (that will create it),
parameterized GetValidators is used for NextConsensus calculation where we
need a list for the current state of the chain.

b483c38593 block/transaction: add network magic into the hash
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.

dde0763840 network: fix compression handling functions
Turns out, Neo uses block compression and not a streaming lz4 format. And it
doesn't contain uncompressed payload size which makes guessing it somewhat
suboptimal.
