instead of using it's own blockNumber to Fork calculation,
we switch to ChainConfig to Fork to ensure smooth transition
when using common block validator.
instead of using stdlib/json, now we switch to json_serialization
the result is much tidier code and more robust when parsing
optional fields.
fixes#635
Move the EVM setup and call in precompile tests to `fixtureCallEvm` in
`call_evm`. Extra return values needed for testing are returned specially, and
the convention for reporting gas used is changed to match `asmCallEvm`.
Although the precompile tests used `execPrecompiles` before, `executeOpcodes`
does perfectly well as a substitute, allowing `fixtureCallEvm` to be shared.
_Significantly, this patch also makes `Computation` more or less an internal
type of the EVM now._
Nothing outside the EVM (except `call_evm`) needs access any more to
`Computation`, `execComputation`, `executeOpcodes` or `execPrecompiles`.
Many imports can be trimmed, some files removed, and EVMC is much closer.
(As a bonus, the functions in `call_evm` reveal what capabilities parts of the
program have needed over time, makes certain bugs and inconsistencies clearer,
and suggests how to refactor into a more useful shared entry point.)

Move the EVM setup and call in fixtures "vm json tests" to new function
`fixtureCallEvm` in `call_evm`. Extra return values needed for testing are
returned specially.
This entry point is different from all other `..CallEvm` type functions,
because it uses `executeOpcodes` instead of `execComputation`, so it doesn't
update the account balance or nonce on entry and exit from the EVM.
The new code is a bit redundant and simplistic intentionally, as the purpose is
to move functionality to `call_evm` with high confidence nothing really
changed. The calls will be jointly refactored afterwards to merge differences.

In the `text_vm_json` ("fixtures") test code, there is another variant of
`rpcSetupComputation` and `txSetupComputation` with slightly different
paremeters. The similarity is obvious.
It is a special setup for testing, though, as it requires slightly different
parameters.

usually, there is always a sender around `getRecipient` call.
no need to recalculate sender. and more important, in some of
JSON-RPC/GraphQL call, the sender is come from `rpcCallData`,
not from `tx.getSender`. or in ohter situation when the tx is
an unsigned tx, without `r,s,v` fields to calculate sender.
Move the EVM setup and call in `macro_assembler` (`runVM`) entirely to new
function `asmCallEvm` in `call_evm`. Extra return values needed for
testing are returned specially from `asmCallEvm`.

The second `asmSetupComputation looks up state by block number and preceding
block number, modifies the first transaction with code for testing, and uses
some parts of that transaction to setup an an EVM test.

In the `macro_assembler` test code, `initComputation` is another variant of
`rpcSetupComputation` and `txSetupComputation` with slightly different
paremeters. The similarity is obvious.
It is a special setup for testing, though, as it requires a contract-creation
transaction for parameters, but sets up a `CALL` execution not `CREATE`.
Gather this into `call_evm`: `initComputation` -> `asmSetupComputation`.

disableParamFiltering() is called in test_all, so its ok when
called via test_all. but when test_generalstate_json or
test_blockchain_json is called independently, and we are using
command line switch, the default param handler from std/unittest
will interfere. hence need to disable it.
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.

In `vm_forks.nim`, `FkBerlin`'s value is (lowercase) `"berlin"`.
Another example of using lowercase in similar code:
`constantinople` in `test_op_bit.nim`
