0bc81aecf4 compiler: do not emit code for unused imported functions 
Our current algorithm marks function as used if it is called
at least ones, even if the callee function is itself unused.
This commit implements more clever traversal to collect usage
information more precisely.

8d562cef99 compiler: allow to use multiple underscores in func arguments 
It should still be present in the argument array in VM so just don't
save them in the map.

0c01d89827 compiler: check that safe methods exist 
If a method is missing from the manifest, it is most likely a typo
or regression after refactoring. There is no "turn-off" flag
for this error because we can do this precisely.

d6bd6b6888 native: drop Refuel method from GAS 
It can be used to attack the network (amplifying DOS), so it's broken
beyond repair. This reverts ac601601c1.

4d1e952be6 go.mod: update go-datastructures to 1.0.53 
We're only using queue library and it didn't change in any way, but 1.0.53 has
proper go.mod, so it's still an improvement.

It at the same time pulls some new packages also like x/tools.

233307aca5 stackitem: completely drop MaxArraySize 
Turns out C# VM doesn't have it since preview2, so our limiting of
MaxArraySize in incompatible with it. Removing this limit shouldn't be a
problem with the reference counter we have, both APPEND and SETITEM add things
to reference counter and we can't exceed MaxStackSize. PACK on the other hand
can't get more than MaxStackSize-1 of input elements.

Unify NEWSTRUCT with NEWARRAY* and use better integer checks at the same time.

Multisig limit is still 1024.

4249674ddc compiler: check for contract permissions 
On many occassions we can determine at compile-time if contract config lacks
some properties it needs. This includes all native contract invocations
through stdlib, as both hashes and methods are known at compile-time
there.

6b3afe9131 compiler: inline all expression with no side-effects, fix #1881 
This has the drawback of traversing expression each time the argument is
used. However this is not the case in our syscall/native wrappers.
The old behaviour can be restored by explicit local assignment.
