f2cb1d5f02 compiler: use constants in interops 
We now support using exported constants, so there is no
need in declaring functions. All functions from `interop/`
are not to be compiled.

Fix #1298.

d5a9d80c12 core: refactor out policy check for transaction 
We were checking blocked accounts twice which is obviously excessive. We also
have our accounts sorted, so we can rely on that in CheckPolicy(). It also
doesn't make much sense to check MaxBlockSystemFee in Blockchain code, policy
contract can handle that.

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.

7c6cdcbcc9 core: fix bug with policy.MaxVerificationGas 
In 121c9664b we should take into account isValid flag of
NativePolicy contract while retrieving MaxVerificationGas native
policy value. Otherwise we won't be able to get MaxVerificationGas
after the node was restarted, because this value is not truly
stored along with the other native policy values.

This commit fixes bug with headers verification after the  node
restarting with an existing storage:

c16bb466a0 stackitem: implement marshaling to JSON with types 
There are 2 kinds of JSON marshaling:
1. Lossy raw marshaling, when type information is lost and
    map keys are expected to be valid utf-8 strings.
2. Almost lossless marshaling, which can handle any non-recursive item.
    Interop value preserves only type.

This commit implements the second.

236438d799 core: do MPT compaction every once in a while 
We need to compact our in-memory MPT from time to time, otherwise it quickly
fills up all available memory. This raises two obvious quesions --- when to do
that and to what level do that.

As for 'when', I think it's quite easy to use our regular persistence interval
as an anchor (and it also frees up some memory), but we can't do that in the
persistence routine itself because of synchronization issues (adding some
synchronization primitives would add some cost that I'd also like to avoid),
so do it indirectly by comparing persisted and current height in `storeBlock`.

Choosing proper level is another problem, but if we're to roughly estimate one
full branch node to use 1K of memory (usually it's way less than that) then we
can easily store 1K of these nodes and that gives us a depth of 10 for our
trie.

6ca22027d5 mpt: implement (*Trie).Collapse() 
Because trie size is rather big, it can't be stored in memory.
Thus some form of caching should also be implemented. To avoid
marshaling/unmarshaling of items which are close to root and are used
very frequenly we can save them across the persists.
This commit implements pruning items at the specified depth,
replacing them by hash nodes.
