Set all necessary context before file traversal, not only import
maps. Also, we can skip restoring import maps because all our code is
processed via `For*` iterators which set necessary context.
We can also refactor this a bit to have all context in one place,
this will be done in #2086.

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.

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.
Create local variables as they are needed and remove `INITSLOT`
if there were no locals. This helps to eliminate a whole class
of bugs when calculated and real amount mismatched.
Because body of multiple `init()` functions constitute single
method in contract, we initialize slot with maximum amount of
locals encounterered in any of `init()` functions and clear them
before emitting body of each instance of `init()`.
Go-way of removing elements from slice is via `append` builtin.
There is a separate opcode for removing elements from
Arrays, which is cheaper and supported in this commit.
Process `init()` functions after global variables has been processed.
It's body is saved into the `_initialize` method where all
initialization is performed.
Function name now consists of 3 parts:
1) full package path
2) method receiver type (if any)
3) function name itself .
Fix#1150.

Invoke `_initialize` method on every call if present.
In NEO3 there is no entrypoint and methods are invoked by offset,
thus `Main` function is no longer required.
We still have special `Main` method in tests to simplify them.
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`.
Closes#913.
Provide package info in the funcScope to check if function is defined
insided an interop package. As a good side-effect bytecode for builtins from `util`
is no longer emitted.
Related #941.
