5a62eb923e smartcontract: fix uint160 marshalling in smartcontract.Parameter 
There's a bug after #785: smartcontract.Parameter of type hash160 should
be marshalled in LE (as default marshaller for uint160 does) instead of
BE, so fixed.

2d0ad30fcf vm: rework Map with internal slice representation 
Which makes iterating over map stable which is important for serialization and
and even fixes occasional test failures. We use the same ordering here as
NEO 3.0 uses, but it should also be fine for NEO 2.0 because it has no
defined order.

3dbe549a61 smartcontract: store MapType Parameter as a slice of KV pairs 
Fixes #809.

Basically, there are three alternative approaches to fixing it:
 * allowing both []byte and string for ByteArrayType value
   minimal invasion into existing code, but ugly as hell and will probably
   backfire at some point
 * storing string values in ByteArrayType
   incurs quite a number of type conversions (and associated data copying),
   though note that these values are not changed usually, so dynamic
   properties of []byte are almost irrelevant here
 * storing only []byte values in ByteArrayType
   makes it impossible to use them as map keys which can be solved in several
   ways:
   - via an interface (Marshalable)
     which is good, but makes testing and comparing values in general harder,
     because of keys mismatch
   - using serialized Parameter as a key (in a string)
     which will need some additional marshaling/unmarshaling
   - converting MapType from map to a slice of key-value pairs
     not a bad idea as we don't use this map as a map really, the type
     itself is all about input/output for real VM types and this approach is
     also a bit closer to JSON representation of the Map

a43c9b9246 compiler: calculate stack size more precisely

665bf78d11 vm: make map serialization more compatible with C# 
C# pushes value and key to the stack of non-serialized items, so key gets
serialized first followed by value. Fixes #806.

Notice though that neither IDictionary in C#, nor map in Go have elements
ordered, so we can easily get a difference in KV pairs order and it would be
impossible to fix.

4758de71ec storage: optimize (*MemCachedStore).Persist for memory-backed ps 
Most of the time it's persisted into the MemoryStore or MemCachedStore, when
that's the case there is no real need to go through the Batch mechanism as it
incurs multiple copies of the data.

Importing 1.5M mainnet blocks with verification turned off, before:
real    12m39,484s
user    20m48,300s
sys     2m25,022s

After:
real    11m15,053s
user    18m2,755s
sys     2m4,162s

So it's around 10% improvement which looks good enough.

bbd802681e cli: make gas parameter to deployment add gas to the base price 
That's how it was intended to behave originally. One thing questionable here
is contract price (policy thing, basically) being moved to smartcontract
package, but it's probably fine for NEO 2.0 (as it won't change) and we'll
make something better for NEO 3.0.

8c902a7223 core: cache UnspentCoins in cachedDao 
1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD,
before:
real    159m16.551s
user    69m58.279s
sys     7m34.334s

after:
real    139m41.836s
user    67m12.477s
sys     6m19.420s

12% which is even a bit more than could be expected from inputs analysis (that
has around 10% cache hits for a block-wide cache), worth doing.

23464401bc core/state: merge spent and unspent coins state, use it to store more things 
This change reduces pressure on DB by doing the following things:
 * not storing additional KV pair for SpentCoin
 * storing Output right in the UnspentCoin, thus eliminating the need to get a
   full transaction from DB

At the same time it makes UnspentCoin more fat and hot, but it should probably
worth it.

Also drop `GetUnspentCoinStateOrNew` as it shouldn't ever existed, UTXOs
can't come out of nowhere.

1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD,
before:
real    302m9.895s
user    96m17.200s
sys     13m37.084s

after:
real    159m16.551s
user    69m58.279s
sys     7m34.334s

So it's almost two-fold which is a great improvement.

b7dee156e2 network: fix a deadlock in DefaultDiscovery 
Why a deadlock can occur:
1. (*DefaultDiscovery).run() has a for loop over requestCh channel.
2. (*DefaultDiscovery).RequestRemote() send to this channel while
    holding a mutex.
3. (*DefaultDiscovery).RegisterBadAddr() tries to take mutex for write.
4. Second select-case can't take mutex for read because of (3).

a9abd3d841 core: fix wrong endian used in interop functions 
C# uses ToArray() or UintXXX(bytes) here which interprets hashes as they
should be interpreted (BE, although they always convert to LE when converting
to String just for the fun of it). It leads to state difference for us at
block 2025204 where even though we have the same value for the key, the key
itself differs, ours:

dd2b538e2a0c1db1ae5061c15be14f916bd1e678e512ffcda6d9499d8e7fe97ee71fd6b8004583d9afe09cc4dadbd5deb63d01e061009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

theirs:

dd2b538e2a0c1db1ae5061c15be14f916bd1e67861e0013db6ded5dbdac49ce0afd9834500b8d61fe77ee97f8e9d49d9a6cdff12e5009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

In this key there is a tx hash encoded
(e512ffcda6d9499d8e7fe97ee71fd6b84583d9afe09cc4dadbd5deb63d01e061 in LE used
by all the tools like neoscan).
