Omnibus update branch

[faddat]

This branch is being used in production by notional on evmos.

The performance is strikingly better, see #248

This branch can be built with ease for chains with high resource demands as follows:

#248

docker run ghcr.io/faddat/cosmos -c /bin/bash
git clone your-chain-repo
cd your-chain-repo
go mod edit -replace github.com/tendermint/tm-db=github.com/notional-labs/tmdb@commit
go mod tidy
go install -ldflags '-w -s -X github.com/cosmos/cosmos-sdk/types.DBBackend=rocksdb' -tags rocksdb ./...

above you can change rocksdb to the database you'd like to try.

In total, this branch integrates

• a fix to rocksdb that allows it to make the snapshots folder
• migration from cosmos/gorockdb to a standard, well-maintained rocks wrapper, linxgnu/grocksdb
• Terra's removal of the prefixdb mutex
• Additional tweaks to goleveldb and rocksdb from the terra team

Though realistically I don't see issues with any of this, except that we'd still be using an out of date rocksdb

NB: All I've really done is the upstreaming work here--

@creachadair sir, I sorta hate to trouble you w/ this but I'm going to r4r this and guess that I'd like to request you be brutal to it. We use this in prod on:

• approximately 100 various nodes that we relay and serve rpcs from
• our evmos and osmosis validators

It has been very stable, but changes many things. If you do not have time for it, I totally understand.

@marbar3778 please note that this is in desperate need of cleanup.

#237 update

[faddat]

FYI, I am keeping this one alive mainly for historical and visibility purposes. I intend to close it this week. I want to grab the goleveldb settings from here though.

This branch contains #250 which some anon coder convinced me didn't include enough evidence. He was right.
