648e0bb242 rpc/smartcontract: merge contract parameter types
Merged two types:
	- smartcontract.ParamType
	- rpc.StackParamType
into single one:
	- smartcontract.ParamType
as they duplicated the functionality.

NOTE: type smartcontract.MapType was added (as in C# implementation).

From now, list of supported smartcontract parameter types:
	UnknownType
	SignatureType
	BoolType
	IntegerType
	Hash160Type
	Hash256Type
	ByteArrayType
	PublicKeyType
	StringType
	ArrayType
	MapType
	InteropInterfaceType
	VoidType

b461a6ab63 compiler: do not short-circuit in complex conditions
Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend
on context. It doesn't even handle simple assignements like
`a := x == 1 && y == 2`.

This commit makes all jumps in such conditions local
and adds tests.

Closes #699, #700.

c258adb532 core: move spent coin management out of the inner storeBlock loop
prevHash == input.PrevHash, so make less DB accesses and more real work. Fix
some bugs along the way:
 * spentCoins structure may already be present in the DB when persisting TX,
   there is nothing wrong with that and we shouldn't overwrite it
 * it's only used for NEO and only to check for claim validity. Thus, when
   processing claim tx the corresponding spentCoins should always be present
   in the DB

eb11e5fb11 core: implement basic policying support, fix #370
Implement mempool and consensus block creation policies, almost the same as
SimplePolicy plugin for C# node provides with two caveats:
 * HighPriorityTxType is not configured and hardcoded to ClaimType
 * BlockedAccounts are not supported

Other than that it allows us to run successfuly as testnet CN, previously our
proposals were rejected because we were proposing blocks with oversized
transactions (that are rejected by PoolTx() now).

Mainnet and testnet configuration files are updated accordingly, but privnet
is left as is with no limits.

Configuration is currently attached to the Blockchain and so is the code that
does policying, it may be moved somewhere in the future, but it works for
now.

The problem is that the select in putPacketIntoQueue() only works the way it
was intended to after the `close(p.done)`, but that happens only after
successful unregistration request send. Thus, do disconnects the other way
around, first unblock queueing and exit goroutines, then destroy the
connection (if it wasn't previously destroyed) and only after that signal to
the Server.
