800321db06 compiler: rename named unused global vars to "_"
So that (*codegen).Visit is able to omit code generation for these
unused global vars. The most tricky part is to detect unused global
variables, it is done in several steps:
1. Collect the set of named used/unused global vars.
2. Collect the set of globally declared expressions that contain
function calls.
3. Pick up global vars from the set made at step 2.
4. Traverse used functions and puck up those global vars that are used
from these functions.
5. Rename all globals that are presented in the set made at step 1
but are not presented in the set made on step 3 or step 4.

1e6b70d570 compiler: adjust TestInline template
Move all auxiliary function declaration after Main, so that INITSLOT
instructions counter works properly. `vmAndCompileInterop` loads program
and moves nextIP to the Main function offset if there's no _init
function. If _init is there, then nextIP will be moved to the start of
_init. In TestInline we don't handle instructions properly (CALL/JMP
don't change nextIP), we just perform instruction traversal from the
start point via Next(), thus INITSLOT counter value depends on the
starting instruction, which depends on _init presence.

91b36657d6 compiler: do not emit code for unnamed unused variables
If variable is unnamed and does not contain function call then it's
treated as unused and code generation may be omitted for it
initialization/declaration.

1dcbdb011a compiler: emit code for unnamed global var decls more careful
In case if global var is unnamed (and, as a consequence, unused) and
contains a function call inside its value specification, we need to emit
code for this var to be able to call the function as it can have
side-effects. See the example:
```
package foo

import "github.com/nspcc-dev/neo-go/pkg/interop/runtime"

var A = f()

func Main() int {
   return 3
}

func f() int {
   runtime.Notify("Valuable notification", 1)
   return 2
}
```

1da4b333f6 cli/wallet: modernize nep11 balances command, unify with nep17
Make NEP-11 code use getnep11balances the same way NEP-17 code uses
getnep17balances. This command was introduced well before getnep11balances
appeared, so it required always specifying contract explicitly. Now this
constraint can be relaxed somewhat in most cases.

7cfcf072b8 cli/wallet: make NEP-17 token selection logic a bit more robust
1. In the single token mode compare known hashes instead of names, names can
   be misleading.
2. Hardcode NEO/GAS, they are special (if not overrided by the wallet data).

5f1fe72504 cli/wallet: use token data from getnepXXbalances
We have this data available since 0.99.1 while all public networks require at
least 0.99.2 for compatibility and NeoFS setups use 0.99.2+ too. This data can
simplify account handling considerably making additional requests unneccessary
in many cases.

e28bf55ebb cli/wallet: search for NEP-11 token name in balances
In the same way we do for NEP-17 tokens. This code predates "getnep11balances"
call, so this wasn't possible back then, but now we can improve the situation
(allow specifying names/symbols instead of hashes only).

8b132cba0c wallet: respect user-locked accounts, don't sign with them
NEP-6 has a notion of locked acccounts and SignTx must respect this user's
choice. For some reason this setting was inappropriately used by our RPC
client tests (probably a different kind of lock was meant).

54c5fd61df wallet: make SignTx more precise and accurate
* each account must have an appropriate signer, if there is no signer for
   this account in the tx it's an error
 * we can only safely append to Scripts when account belongs to the next
   signer (we don't have appropriate verification scripts for other signers)
 * when contract has one parameter, the signature shouldn't be appended to
   other data

I think these rules allow to handle more cases and do that safer. We have more
complex scenarios though, like non-signature parameters or mixed-parameter
invocation scripts, but that's out of scope for now.

7a930a8e11 wallet: don't fail in SignTx when no contract provided

59fbc689e4 vm/bench: extend refcounter benchmarks
Adding an array multiple times leads to the fast update via `IncRC`.
This hides the allocation that is there on the first addition. In this
commit add another benchmark which measures Add/Remove together, to
ensure that `switch` in `refCounter.Add` is entered. Benchmark results
are meaningful, because `Add`/`Remove` have almost identical implementation.

98dfe66466 rpcsrv: simplify calculatenetworkfee
We're dealing with a transaction here and it can't be decoded successfully
unless it has an appropriate number of witness scripts (matching the number of
signers) with appropriate hashes (matching signers). So this iterations make
no sense at all, we know exactly where to look for the
verification/invocation scripts.

eeeb0f6f0e core: accept two-side channels for sub/unsub, read on unsub
Blockchain's notificationDispatcher sends events to channels and these
channels must be read from. Unfortunately, regular service shutdown procedure
does unsubscription first (outside of the read loop) and only then drains the
channel. While it waits for unsubscription request to be accepted
notificationDispatcher can try pushing more data into the same channel which
will lead to a deadlock. Reading in the same method solves this, any number of
events can be pushed until unsub channel accepts the data.
