remove relative paths ./ and ../ from import section
why:
  relative paths make sources inherently non-relocatable

details:
  import base is set to the nimbus directoy, so importing ./stack
  from file interpreter.nim becomes vm/stack etc.

caveat:
   a file named nimbus/strformat.nim would clash with strformat (but
   not with std/strformat)

Refactor interpreter dispatch (#65)
* move forks constants, rename errors

* Move vm/utils to vm/interpreter/utils

* initial opcodes refactoring

* Add refactored Comparison & Bitwise Logic Operations

* Add sha3 and address, simplify macro, support pop 0

* balance, origin, caller, callValue

* fix gas copy opcodes gas costs, add callDataLoad/Size/Copy, CodeSize/Copy and gas price opcode

* Update with 30s, 40s, 50s opcodes + impl of balance + stack improvement

* add push, dup, swap, log, create and call operations

* finish opcode implementation

* Add the new dispatching logic

* Pass the opcode test

* Make test_vm_json compile

* halt execution without exceptions for Return, Revert, selfdestruct (fix #62)

* Properly catch and recover from EVM exceptions (stack underflow ...)

* Fix byte op

* Fix jump regressions

* Update for latest devel, don't import old dispatch code as quasiBoolean macro is broken by latest devel

* Fix sha3 regression on empty memory slice and until end of range slice

* Fix padding / range error on expXY_success (gas computation left)

* update logging procs

* Add tracing - expXY_success is not a regression, sload stub was accidentally passing the test

* Reuse the same stub as OO implementation

* Delete previous opcode implementation

* Delete object oriented fork code

* Delete exceptions that were used as control flows

* delete base.nim 🔥, yet another OO remnants

* Delete opcode table

* Enable omputed gotos and compile-time gas fees

* Revert const gasCosts -> generates SIGSEGV

* inline push, swap and dup opcodes

* loggers are now template again, why does this pass new tests?

* Trigger CI rebuild after rocksdb fix https://github.com/status-im/nim-rocksdb/pull/5

* Address review comment on "push" + VMTests in debug mode (not release)

* Address review comment: don't tag fork by default, make opcode impl grepable

* Static compilation fixes after rebasing

* fix the initialization of the VM database

* add a missing import

* Deactivate balance and sload test following #59

* Reactivate stack check (deactivated in #59, necessary to pass tests)

* Merge remaining opcodes implementation from #59

* Merge callDataLoad and codeCopy fixes, todo simplify see #67

Reorganize VM/interpreter + cleanup (#52)
* Move and cleanup interpreter files - prepare for redesign of VM

* fix call comment aobut recursive dependencies

* memory: use a template again and avoid (?) a cstring-> string conversion

* Fix stack test regression

* Fix recursive dependency on logging_ops, test_vm_json compiles but regression :/

* Fix signextend regression

* Fix 3 signed test and sha3 test
