Follow neo-project/neo#365. neo-vm submodule is updated just to show the
relevant latest commit, nothing really changed there.

324f4c265b stackitem: don't copy existing slices for TryBytes
Most often we only need to read them and it doesn't require copying. Make an
explicit copy (and copy only things we need!) where needed.

After the recent neo-vm tests update our vm package testing time jumped to
~12s, with this change it's now more like ~8s.

74097ae8b0 stackitem: add NewPointerWithHash() to save on hash calculations
Inspired by neo-project/neo-vm#352. We can't directly compare slices, so we're
better optimize things we already have. At the same time this code would
behave a bit different if A is to call B and then B is call A and then some
pointer from the first A invocation is to be compared with a pointer from the
second A invocation. Not sure it really matters.

681e81420a vm: make (*Context).IP() return instruction pointer
It is misleading to return +1 in code, and user representation

a080d24cf5 vm: fix debugger and add tests
1. `Run()` must be able to continue execution after a breakpoint.
2. VM must stop right before the breakpoint, not after.
3. Initial vm state is NONE, not HALT.

bf01599430 vm: check return value on context unload
When calling external contracts we expect exactly 1 value to be on
stack. For methods returning nothing, `Null` value is pushed, otherwise
it is an error.`

0e2784cd2c always wrap errors when creating new ones with fmt.Errorf()
It doesn't really change anything in most of the cases, but it's a useful
habit anyway.

5ef08f60ae remove github.com/pkg/errors from dependencies
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.

c16bb466a0 stackitem: implement marshaling to JSON with types
There are 2 kinds of JSON marshaling:
1. Lossy raw marshaling, when type information is lost and
    map keys are expected to be valid utf-8 strings.
2. Almost lossless marshaling, which can handle any non-recursive item.
    Interop value preserves only type.

This commit implements the second.
