simplify EVM and delegete those things to accounts cache.
also no more manual state clearing, accounts cache will be
responsible for both collecting touched account and perform
state clearing.
Two unresolved items currently:
- Three tests that are temporarily disabled as they fail in the
macro_assembler code, which seems to be due to an ambigious
identifier Stop (Ops and chronos ServerCommand enum).
- i386 CI disabled as it fails at Nim compilation already. Failed
tests where already ignored for this target.
* Redesign of BaseVMState descriptor
why:
BaseVMState provides an environment for executing transactions. The
current descriptor also provides data that cannot generally be known
within the execution environment, e.g. the total gasUsed which is
available not before after all transactions have finished.
Also, the BaseVMState constructor has been replaced by a constructor
that does not need pre-initialised input of the account database.
also:
Previous constructor and some fields are provided with a deprecated
annotation (producing a lot of noise.)
* Replace legacy directives in production sources
* Replace legacy directives in unit test sources
* fix CI (missing premix update)
* Remove legacy directives
* chase CI problem
* rebased
* Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation
why:
Constructing a new 'AccountsCache' descriptor can be avoided sometimes
when the current state root is properly positioned already. Such a
feature existed already as the update function 'initStateDB()' for the
'BaseChanDB' where the accounts cache was linked into this desctiptor.
The function 'initStateDB()' was removed and re-implemented into the
'BaseVmState' constructor without optimisation. The old version was of
restricted use as a wrong accounts cache state would unconditionally
throw an exception rather than conceptually ask for a remedy.
The optimised 'BaseVmState' re-initialisation has been implemented for
the 'persistBlocks()' function.
also:
moved some test helpers to 'test/replay' folder
* Remove unused & undocumented fields from Chain descriptor
why:
Reduces attack surface in general & improves reading the code.
File `vm_types2` is obsolete. Remove this file and divert all imports to the
common forks list outside the EVM, or in some cases they don't need it anyway.

The conditions mentioned in the old TODO comment have been checked. All
fixtures have either 40 hex digits or empty string for "to". There is a test
with all-zeros, and it means send to that account, not contract creation.
Empty string means contract creation.
This patch does not change the relaxed parsing where fewer than 40 digits is
accepted. We should probably be stricter about this.

when a skipped test case not in the skip list
but skipped using `testStatusIMPL`, the generated
markdown file list it as failed.
now that bug is fixed.
The "new block chain json tests" were being skipped on Linux, but silently so
that CI didn't notice. These are a significant part of the Ethereum test suite.
See the missing output from `make test`, also visible in CI logs for Linux
targets (prior to this commit):
[OK] tests/fixtures/eth_tests/TransactionTests/ttGasPrice/TransactionWithGasPriceOverflow.json
[OK] tests/fixtures/eth_tests/TransactionTests/ttGasPrice/TransactionWithHighGasPrice.json
[Suite] new block chain json tests
<-- nothing here
[Suite] Fork ID tests
[OK] MainNet
[OK] RopstenNet
Commit 3d468a7 (`fixes path pointing to eth_tests`) renamed the JSON fixture
source directoryf in the witness-builder tests but not the regular blockchain
tests. As a result, searching for JSON test files yielded zero results. To
make this less likely in future, zero results is now an error.
