Prior to this patch, top-level EVM executions and nested EVM executions did
their `getStorage` and other requests using a completely different set of host
functions. It was just unfinished, to get top-level "new" EVMC working.
This finishes the job - it stops using the old methods. Effect:
- Functionality added at the EVMC host level will be used by all EVM calls.
(The target here is Beam Sync).
- The old set of functions are no longer used, so they can be removed.
- When EVMC host call tracing is enabled (`showTxCalls = true`), it traces
the calls from nested EVM executions as well as top-level.

We've been filling a "vtable"-like at run time, but it's not necessary.
The new object is a global `let x = evmc_host_interface(...)`, we assume it's
initialised before the first use, and we take its address with `.unsafeAddr`.
(If we use `ref evmc_host_interface`, Nim decides (correctly) that the
functions which use it aren't GC-safe because it's a global.)

This combines two things, a C stack usage change with EVM nested calls
via EVMC, and changes to host call tracing.
Feature-wise, the tracing is improved:
- Storage keys and values are make more sense.
- The message/result/context objects are shown with all relevant fields.
- `call` trace is split into entry/exit, so these can be shown around the
called contract's operations, instead of only showing the `call` parameters
after the nested call is finished.
- Nested calls are indented, which helps to highlight the flow.
- C stack usage considerably reduced in nested calls when more functionality
is enabled (either tracing here, or other things to come).
This will seem like a minor patch, but C stack usage was the real motivation,
after plenty of time in the debugger.
Nobody cares about stack when `showTxCalls` (you can just use a big stack when
debugging). But these subtle changes around the `call` path were found to be
necessary for passing all tests when the EVMC nested call code is completed,
and that's a prerequisite for many things: async EVM, dynamic EVM, Beam Sync,
and to fix https://github.com/status-im/nimbus-eth1/issues/345.

The update for London (EIP-1559) in 1cdb30df ("bump nim-emvc with evmc revision
8.0.0 to 9.0.0") really bumped EVMC ABI version from 7.5 up to 9.
In other words, it skipped Berlin, going direct from Istanbul to London.
That was accompanied by EVMC changes in 05e9b891 ("EIP-3198: add baseFee op
code in nim-evm"), which added the API changes needed for London.
But the missing Berlin functions weren't added in the move to London.
As a result, our EVMC host became incompatible with Berlin, London, and really
all revisions of the ABI, and if a third party EVM was loaded, it crashed.
This commit adds the missing Berlin host support, and makes our ABI
binary-compatible with real EVMC again.

although they are technically different, but in reality,
many networks are using the same id for ChainId dan NetworkId.
in this commit, we set networkid from config file's chainId.
- allow clique period and epoch to be configured via config file
- this also activate poaEngine mode
- remove clique period configuration from cli to reduce confusion

- Use caps for log-levels in tests
- Perform utf-8 validation at message boundaries (#90)
json-rpc:

As this branch of vm2 doesn't support EVMC, this EVMC-motivated change is only
required here for internal compatibility.

This changes fixes a bug in `CREATE2` ops when used with EVMC.
Because it changes the salt type, it affects non-EVMC code as well.
The salt was passed through EVMC with the wrong byte order, although this went
unnoticed as the Nimbus host flipped the byte order before using it.
This was found when running Nimbus with third-party EVM,
["evmone"](https://github.com/ethereum/evmone).
There are different ways to remedy this.
If treated as a number, Nimbus EVM would byte-flip the value when calling EVMC,
then Nimbus host would flip the received value. Finally, it would be flipped a
third time when generating the address in `generateSafeAddress`. The first two
flips can be eliminated by negotiation (like other numbers), but there would
always be one flip.
As a bit pattern, Nimbus EVM would flip the same way it does when dealing with
hashes on the stack (e.g. with `getBlockHash`). Nimbus host wouldn't flip at
all - and when using third-party EVMs there would be no flips in Nimbus.
Because this value is not for arithmetic, any bit pattern is valid, and there
shouldn't be any flips when using a third-party EVM, the bit-pattern
interpretation is favoured. The only flip is done in Nimbus EVM (and might be
eliminated in an optimised version).
As suggested, we'll define a new "opaque 256 bits" type to hold this value.
(Similar to `Hash256`, but the salt isn't necessarily a hash.)

Nimbus types generally use the bit count not the byte count, e.g. `UInt256`,
`Hash256`, so make `ZERO_HASH256` (which has type `Hash256`) fit this pattern.

* Provide PoA voting header generator
why:
Handy for hive/smoke test
details:
Header generator is a re-implementation of the generator previously
used for the canonical reference tests.
* try fixing ci out-of-mem condition
why:
for some reason, the ci began behaving like a real win7/i386 machine
where gcc is limited to 64k optimiser space
* fix comments, typos ..
new command line options:
--ws Enable the Websocket JSON-RPC server
--wsbind:<value> Set address:port pair(s) (comma-separated) Websocket JSON-RPC server will bind to (default: localhost:8546)
--wsapi:<value> Enable specific set of Websocket RPC API from list (comma-separated) (available: eth, debug)
fixes#770
new command line options:
--clique-period:<value> Enables clique support. value is block time in seconds
--engine-signer:<value> Enables mining. value is EthAddress in hex
--import-key:<path> Import unencrypted 32 bytes hex private key file
fixes#771
* Provide API
details:
API is bundled via clique.nim.
* Set extraValidation as default for PoA chains
why:
This triggers consensus verification and an update of the list
of authorised signers. These signers are integral part of the
PoA block chain.
todo:
Option argument to control validation for the nimbus binary.
* Fix snapshot state block number
why:
Using sub-sequence here, so the len() function was wrong.
* Optional start where block verification begins
why:
Can speed up time building loading initial parts of block chain. For
PoA, this allows to prove & test that authorised signers can be
(correctly) calculated starting at any point on the block chain.
todo:
On Goerli around blocks #193537..#197568, processing time increases
disproportionally -- needs to be understand
* For Clique test, get old grouping back (7 transactions per log entry)
why:
Forgot to change back after troubleshooting
* Fix field/function/module-name misunderstanding
why:
Make compilation work
* Use eth_types.blockHash() rather than utils.hash() in Clique modules
why:
Prefer lib module
* Dissolve snapshot_misc.nim
details:
.. into clique_verify.nim (the other source file clique_unused.nim
is inactive)
* Hide unused AsyncLock in Clique descriptor
details:
Unused here but was part of the Go reference implementation
* Remove fakeDiff flag from Clique descriptor
details:
This flag was a kludge in the Go reference implementation used for the
canonical tests. The tests have been adapted so there is no need for
the fakeDiff flag and its implementation.
* Not observing minimum distance from epoch sync point
why:
For compiling PoA state, the go implementation will walk back to the
epoch header with at least 90000 blocks apart from the current header
in the absence of other synchronisation points.
Here just the nearest epoch header is used. The assumption is that all
the checkpoints before have been vetted already regardless of the
current branch.
details:
The behaviour of using the nearest vs the minimum distance epoch is
controlled by a flag and can be changed at run time.
* Analysing processing time (patch adds some debugging/visualisation support)
why:
At the first half million blocks of the Goerli replay, blocks on the
interval #194854..#196224 take exceptionally long to process, but not
due to PoA processing.
details:
It turns out that much time is spent in p2p/excecutor.processBlock()
where the elapsed transaction execution time is significantly greater
for many of these blocks.
Between the 1371 blocks #194854..#196224 there are 223 blocks with more
than 1/2 seconds execution time whereas there are only 4 such blocks
before and 13 such after this range up to #504192.
* fix debugging symbol in clique_desc (causes CI failing)
* Fixing canonical reference tests
why:
Two errors were introduced earlier but ovelooked:
1. "Remove fakeDiff flag .." patch was incomplete
2. "Not observing minimum distance .." introduced problem w/tests 23/24
details:
Fixing 2. needed to revert the behaviour by setting the
applySnapsMinBacklog flag for the Clique descriptor. Also a new
test was added to lock the new behaviour.
* Remove cruft
why:
Clique/PoA processing was intended to take place somewhere in
executor/process_block.processBlock() but was decided later to run
from chain/persist_block.persistBlock() instead.
* Update API comment
* ditto
