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

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.

Fix #350.

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.

Implement 3 new instructions: TRY,ENDTRY,ENDFINALLY.
1. TRY marks the start of the block where exceptions are catched.
    It has 2 arguments which are relative offsets of exception handler
    and the end of the whole try/catch construction.
2. ENDTRY denotes either end of try or catch block.
3. ENDFINALLY denotes end of finally block which is executed
    irregardless of whether an exception has occured.
