jangko d7f1d698ce EIP-4399 implementation of nim-vm2
new addition:

eip2718: rename vm2 ChainId op code to ChainIdOp
this is to avoid clash with ChainId type
imported from eth/common

Jordan Hrycaj 5d0d44c38f re-named compu_helper.nim => computation.nim
why:
  exports all except one of the original computation.nim functional
  objects

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 3ed234e0a1 clean up cyclic-import-breaker function stubs where possible for op handlers
why:
  using function stubs made it possible to check the syntax of an op
  handler source file by compiling this very file. this was previously
  impossible due cyclic import/include mechanism.

details:
  only oph_call.nim, oph_create.nim and subsequently op_handlers.nim
  still need the -d:kludge:1 flag for syntax check compiling. this flag
  also works with interpreter_dispatch.nim which imports op_handlers.nim.

Jordan Hrycaj b2ce6d9e70 re-arrange functions from v2computation.nim and interpreter_dispatch.nim
why:
  step towards breaking circular dependency

details:
  some functions from v2computation.nim have been extracted into
  compu_helper.nim which does not explicitly back-import
  v2computation.nim. all non recursive op handlers now import this source
  file rather than v2computation.nim.

  recursive call/create op handler still need to import v2computation.nim.

  the executeOpcodes() function from interpreter_dispatch.nim has been
  moved to v2computation.nim which allows for <import> rather than
  <include> the interpreter_dispatch.nim source.

Jordan Hrycaj 9b70ab5f8f update handler prototype using call-by-reference argument
why:
  this allows for passing back information which can eventually be
  used for reducing use of exceptions

caveat:
  call/create currently needs to un-capture the call-by-reference
  (wrapper) argument using the Computation reference inside

Jordan Hrycaj 51587208b4 verifying new op handler tables layout against original tables
why:
  the previous approach was replacing the function-lets in
  opcode_impl.nim by the particulate table handlers. the test
  functions will verify the the handler functions are sort of
  correct but not the assignments in the fork tables.

  the handler names of old and new for tables are checked here.

caveat:
  verifying tables currently takes a while at compile time.
