network: do not allow to request invalid block count
...
The problem is in peer disconnection due to invalid GetBlockByIndex
payload (the logs are from some patched neo-go version):

```
GetBlockByIndex payload can't be decoded, and the only possible cause
is zero (or <-1, but it's probably not the case) block count requested.
Error is improved as far.

network: remove priority queue from block queue
...
Use circular buffer which is a bit more appropriate. The problem is that
priority queue accepts and stores equal items which wastes memory even in
normal usage scenario, but it's especially dangerous if the node is stuck for
some reason. In this case it'll accept from peers and put into queue the same
blocks again and again leaking memory up to OOM condition.
Notice that queue length calculation might be wrong in case circular buffer
wraps, but it's not very likely to happen (usually blocks not coming from the
queue are added by consensus and it's not very fast in doing so).

network: fix block relaying, don't spit out useless errors
...
We can only add one block of the given height and we have two competing
goroutines to do that --- consensus and block queue. Whomever adds the block
first shouldn't trigger an error in another one.
Fix block relaying for blocks added via the block queue also, previously one
consensus-generated blocks were broadcasted.

This one will replace blockCache in Blockchain itself as it can and should be
external from it. The idea is that we only feed successive blocks into the
Blockchain and it only stores valid proper Blockchain and nothing else.
