Unified database frontend integration (#1670)
* Nimbus folder environment update

details:
* Integrated `CoreDbRef` for the sources in the `nimbus` sub-folder.
* The `nimbus` program does not compile yet as it needs the updates
  in the parallel `stateless` sub-folder.

* Stateless environment update

details:
* Integrated `CoreDbRef` for the sources in the `stateless` sub-folder.
* The `nimbus` program compiles now.

* Premix environment update

details:
* Integrated `CoreDbRef` for the sources in the `premix` sub-folder.

* Fluffy environment update

details:
* Integrated `CoreDbRef` for the sources in the `fluffy` sub-folder.

* Tools environment update

details:
* Integrated `CoreDbRef` for the sources in the `tools` sub-folder.

* Nodocker environment update

details:
* Integrated `CoreDbRef` for the sources in the
  `hive_integration/nodocker` sub-folder.

* Tests environment update

details:
* Integrated `CoreDbRef` for the sources in the `tests` sub-folder.
* The unit tests compile and run cleanly now.

* Generalise `CoreDbRef` to any `select_backend` supported database

why:
  Generalisation was just missed due to overcoming some compiler oddity
  which was tied to rocksdb for testing.

* Suppress compiler warning for `newChainDB()`

why:
  Warning was added to this function which must be wrapped so that
  any `CatchableError` is re-raised as `Defect`.

* Split off persistent `CoreDbRef` constructor into separate file

why:
  This allows to compile a memory only database version without linking
  the backend library.

* Use memory `CoreDbRef` database by default

detail:
 Persistent DB constructor needs to import `db/core_db/persistent

why:
 Most tests use memory DB anyway. This avoids linking `-lrocksdb` or
 any other backend by default.

* fix `toLegacyBackend()` availability check

why:
  got garbled after memory/persistent split.

* Clarify raw access to MPT for snap sync handler

why:
  Logically, `kvt` is not the raw access for the hexary trie (although
  this holds for the legacy database)

EVM state transition tool

The t8n tool is a stateless state transition utility.

Build instructions

There are few options to build t8n tool like any other nimbus tools.

  1. Use your system Nim compiler(v1.6.12) and git to install dependencies.
    $> git submodule update --init --recursive
    $> ./env.sh (run once to generate nimbus-build-system.paths)
    $> nim c -d:release -d:chronicles_default_output_device=stderr tools/t8n/t8n
    $> nim c -r -d:release tools/t8n/t8n_test
    
  2. Use nimbus shipped Nim compiler and dependencies.
    $> make update deps
    $> ./env.sh nim c -d:release -d:chronicles_default_output_device=stderr tools/t8n/t8n
    $> ./env.sh nim c -r -d:release tools/t8n/t8n_test
    
  3. Use nimbus makefile.
    $> make update
    $> make t8n
    $> make t8n_test
    

Command line params

Available command line params

Usage:

t8n [OPTIONS]...

The following options are available:

 --trace                 Output full trace logs to files trace-<txIndex>-<txhash>.jsonl [=false].
 --trace.memory          Enable full memory dump in traces [=false].
 --trace.nostack         Disable stack output in traces [=false].
 --trace.returndata      Enable return data output in traces [=false].
 --output.basedir        Specifies where output files are placed. Will be created if it does not exist.
 --output.body           If set, the RLP of the transactions (block body) will be written to this file.
 --output.alloc          Determines where to put the `alloc` of the post-state. [=alloc.json].
                             `stdout` - into the stdout output.
                             `stderr` - into the stderr output.
                             <file>   - into the file <file>.
 --output.result         Determines where to put the `result` (stateroot, txroot etc) of the post-state.
                             [=result.json].
                             `stdout` - into the stdout output.
                             `stderr` - into the stderr output.
                             <file>   - into the file <file>.
 --input.alloc           `stdin` or file name of where to find the prestate alloc to use. [=alloc.json].
 --input.env             `stdin` or file name of where to find the prestate env to use. [=env.json].
 --input.txs             `stdin` or file name of where to find the transactions to apply. If the file
                             extension is '.rlp', then the data is interpreted as an RLP list of signed
                             transactions. The '.rlp' format is identical to the output.body format.
                             [=txs.json].
 --state.reward          Mining reward. Set to -1 to disable [=0].
 --state.chainid         ChainID to use [=1].
 --state.fork            Name of ruleset to use. [=GrayGlacier].
