Since these types were written, we've gained an executable spec:
https://github.com/ethereum/execution-specs
This PR aligns some of the types we use with this spec to simplify
comparisons and cross-referencing.
Using a `distinct` type is a tradeoff between nim ergonomics, type
safety and the ability to work around nim quirks and stdlib weaknesses.
In particular, it allows us to overload common functions such as `hash`
with correct and performant versions as well as maintain control over
string conversions etc at the cost of a little bit of ceremony when
instantiating them.
Apart from distinct byte types, `Hash32`, is introduced in lieu of the
existing `Hash256`, again aligning this commonly used type with the spec
which picks bytes rather than bits in the name.
Other implementations of MPT delete entries when attempting to put empty
value, because empty value cannot exist in RLP. We should match the
behaviour.

Also cross-checked with Geth and Ethereumjs implementations.

This reverts commit 4754543605.
* In the incomplete-db node-existence check, don't use contains.
(Using contains led to a problem with CaptureDB.)
* In the incomplete-db check, just checking len > 0 isn't right.
* Oh, I needed the AssertionDefect thing too.
* Need this when compiling under older versions of Nim.
* Sometimes we want missing nodes to be errors, sometimes not.
`eth_types` is being imported from many projects and ends up causing
long build times due to its extensive import lists - this PR starts
cleaning some of that up by moving the chain DB and RLP to their own
modules.
this PR also moves `keccakHash` to its own module and uses it in many
places.
* Fix raw Exceptions in hexary caused by forward declarations
* Fix raw Exceptions in trie/db caused by forward declarations
* And now we can remove those db Proc CatchableError raises
* Add build_dcli target and add it to CI
* Fix local imports for dcli
* And use local imports for all other files too
* Use local imports in tests and rlpx protocols
* port kvstore from nim-beacon-chain
* remove old database backends
* use kvstore in trie database
* add sqlite dep
* avoid template param double evaluation
* clean up heterogenous lookup todo
