All commits except the last two constitute PRs #43 and #44. The last two reverted files such that only changes to the `pseudo` and `ethtest` packages remain; once this is merged into the `libevm` branch then `libevm` will be merged into the branch for #44 too. Cherry-picking commits was not possible as some touched both halves of the changes; the squash-merges will, however, make this convoluted history irrelevant. * feat: `types.StateAccount` pseudo-generic payload * feat: registration of `StateAccount` payload type * chore: mark `eth/tracers/logger` flaky * chore: copyright header + `gci` * test: lock default `types.SlimAccount` RLP encoding * feat: `vm.SlimAccount.Extra` from `StateAccount` equiv * chore: placate the linter * test: `pseudo.Type.EncodeRLP()` * test: `pseudo.Type.DecodeRLP()` * fix: `pseudo.Type.DecodeRLP()` with non-pointer type * feat: `pseudo.Type.IsZero()` and `Type.Equal(*Type)` * feat: `types.StateAccountExtra.DecodeRLP()` * chore: revert non-pseudo-package modifications * chore: delete non-pseudo-package additions

Why this should be merged
Allows
types.StateAccountto mirrorava-labs/corethbehaviour w.r.t. RLP encoding (i.e.IsMultiCoin) while maintaining backwards compatibility.How this works
This is very similar to
params.RegisterExtras()except that it's in thetypespackage.The
pseudo.Type.Format()method was necessary to avoid changing upstream formatting verbs.How this was tested
RLP encodings of vanilla-geth
types.StateAccountandtypes.SlimAccountwere first locked in with unit tests, before any libevm modidifcations. Similar test cases were generated fromava-labs/corethwithIsMultiCoin boolto be mirrored withtypes.RegisterExtras[bool](). Round-trip RLP encoding/decoding demonstrates correct behaviour for both geth and coreth use cases.
