Allow to invoke methods by offset:
1. Every invoked contract must have manifest.
2. Check arguments count on invocation.
3. Change AppCall to a regular syscall.
4. Add test suite for `System.Contract.Call`.
GetScriptContainer() interop can try to get this transaction and this attempt
will lead to hash calculation with transaction serialization, but transaction
can't be successfully serialized if it doesn't have a script set, so this
makes test invocations fail.
We were accepting transactions with zero system fee, but we shouldn't do
that. Also, transaction's verification execution has to be limited by network
fee.
The script is passed as a hex string, but no one should care. The hash is a
hex-encoded LE value, but no one should care either. Hex might change to
base64, LE to BE, no one outside these functions should care about that.
Implement (*Param).GetBoolean() for converting parameter to bool value.
It is used for verbosity flag and is false iff it is either zero number
or empty sting.
This error message makes no sense when shutting down the server:
2020-06-25T19:29:53.251+0300 ERROR failed to start RPC server {"error": "http: Server closed"}
And ListenAndServer is documented to always return non-nil error one of which
is http.ErrServerClosed. This should also fix the following test failure:

==================
ValidatorsCount is not initialized at block 0 with C# node (the first voter
initializes it) and until that initialization happens the standby validators
list is being returned as is without sorting.
Fixes state mismatch for the key ffffffff0e00000000000000000000000000000001 in
the first blocks.
It also affects tests as now the first validator is different and it receives
the network fees.
There is no such thing as high/low priority transactions, as there are
no free transactions anymore and they are ordered by fees contained
in transaction itself.
Closes#1063.
It's just JSON, io.Serializable is only used for DB storage where the length
should be obtained from the stream. Fixes:
2020-06-18T22:14:10.571+0300 WARN contract invocation failed {"tx": "1ffd475a9c246495d6206cb80a9a78e9d14a433ded60cd37aa87d897655606e1", "block": 25893, "error": "error encountered at instruction 3696 (SYSCALL): failed to invoke syscall: invalid character ':' after top-level value"}
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.
It doesn't affect anything yet, but it's going to be used in the future for
network-specific behavior. It also renames short '--timeout' form to '-s'
avoiding conlict with '-t' used for '--testnet'.
1. Remove GetScript, IsPayable, GetStorageContext.
2. Revert 82319538 related to GetStorageContext.
3. Rename Migrate to Update.
4. Move remaining to System.Contract.*.
Related #1031.
