* chore: Fix golangci-lint configuration and patch errors
Due to misconfiguration of a linting rules directory, our linter has not been
working properly. This change fixes the configuration issue, and all remaining
linting errors.
* Fix race in peer logging
* Fix race and return
* Lock on bufferred amount low
* Fix mutex lock
* chore: Initial database scaffolding
This implements migrations and code generation for interfacing with a PostgreSQL database.
A dependency is added for the "postgres" binary on the host, but that seems like an acceptable requirement considering it's our primary database.
An in-memory database object can be created for simple cross-OS and fast testing.
* Run tests in CI
* Use Docker instead of binaries on the host
* Skip database tests on non-Linux operating systems
* chore: Add golangci-lint and codecov
* Use consistent file names
