## Description

Since events are not hashed into the header they can be non deterministic. Changing an event is not consensus breaking. Will update docs in the spec

i.e. without double pointer. With double pointer, it was possible to
submit `null` value, which will crash the server.

Closes #6146

## Description

Fixes marshaling error in sdk

closes https://github.com/cosmos/cosmos-sdk/issues/8578

the output stays the same, we are avoiding the passing of the callback because sdk uses typed logging.

Co-authored-by: Marko <marbar3778@yahoo.com>

This reverts commit afd07096a7.

I had believed that this tooling change could have been what broke our
GoReleaser flow; I now know that it was a result of changes in Go 1.16
and an update to GoReleaser! GoReleaser has now been updated again
and our flow should be un-broken.

This reverts commit 1b2174a0da.

Executed a local network using simapp and looked for logs that seemed superfluous. This isn't by any means an exhaustive grooming, but should drastically help legibility of logs.

## Description
 
- bump deadlock dep to master
  - fixes `make test` since we now use `deadlock.Once`

Closes: #XXX

- Reduce duplication in messages and metrics.
- merge WAL interfaces. Meant to push the developer to make changes in both places.
