vm2: Remove vm2 `forks_list` everywhere, use common forks list
Remove file vm2 file `forks_list, and divert all imports to the common forks
list outside the EVM.

EVM: Apply EIP-6 in the code (affects both vm and vm2)
The rationale in EIP-6[1] for changing names to `selfDestruct` applies to code
as much as it does to specs.  Also, Ethereum uses the new names consistently,
so it's useful for our code to match the terms used in later EIP specs and
testsuite entries.

This change is straightforward, and is a prerequisite for patches to come that
do things with the `selfDestruct` fields.

Jordan Hrycaj 5d0d44c38f re-named compu_helper.nim => computation.nim
why:
  exports all except one of the original computation.nim functional
  objects
2021-04-28 15:24:14 +03:00
Jordan Hrycaj 028a3d6a37 removed redundant source file: interpreter.nim
why:
  works as import concentrator for state_transaction.nim for
  vm_internals.nim interface.

Jordan Hrycaj ff6921eb1a re-named some v2*.nim sources to its original name *.nim (without the v2)
why:
  the v2 prefix of the file name was used as a visual aid when
  comparing vm2 against vm sources

details:
  all renamed v2*.nim sources compile locally with the -d:kludge:1 flag
  set or without (some work with either)

  only sources not renamed yet: v2state_transactions.nim

Jordan Hrycaj e02c6d4c3d renamed computation.nim, memory.nim, utils_numeric.nim, interpreter.nim => v2*.nim
why:
  these files provide part of the externally accessible interface
  provided by vm_cpmputation.nim, vm_internals.nim. so the
  new filename indicates that the source code belongs to vm2 (rather
  than vm).

Jordan Hrycaj b4f8450968 provide identical copy of vm folder => vm2, activated by make flag ENABLE_VM2=1
why:
  vm2 enabled by ENABLE_VM2=1 behaves as vm without ENABLE_EVMC=1 until
  it doesn't in some future fatch set. this leaves some wiggle room
  to work on a vm copy without degrading the original implementation.

details:
  + additional make flag ENABLE_VM2=1 (or ENABLE_VM2=0 to explicitely disable)
  + when both flags ENABLE_EVMC=1 and ENABLE_VM2=1 are present, the former
    flag ENABLE_EVMC=1 takes precedence, this is implemented at the NIM
    compiler level for -d:evmc_enabled and -d:vm2_enabled

merge vm_memory, vm_interpreter, and vm_utils_numeric => vm_internals
why:
  currently used for tests only
