* Enable safe linters
Enable the linters dogsled, rowserrcheck, and sqlclosecheck.
These report no errors currently in the code base.
Enable misspell.
Misspell finds two spelling mistakes in comments, which are fixed by the
patch as well.
Add and sort linters which are relatively
safe to add over time. Comment them out for now.
* Close the response body
If we can get a HTTP response, it has a body which ought to be closed.
By doing so, we avoid potentially leaking connections.
* Enable the exportloopref linter
There are two places in the code with these warnings. Fix them while
enabling the linter.
* Remove redundant types in tests
If a slice already determines the type, the inner type declaration is
redundant. Remove the inner declarations.
* Mark autotag test cases as parallel
Autotag test cases is by far the outlier when it comes to test time.
While go test runs test cases in parallel,
it doesn't do so inside a given package, unless one marks the test cases
as parallel.
This change provides a significant speedup on a 8-core machine for test
runs.
* Fix all revive warnings in the code base
All of these are of the form
```
var Identifier Type = Expr
```
where the `Type` is known from the output of `Expr` and can be omitted
as a result.
* Handle unchecked errors
* Remove new-from-rev
Since the project passes all linter checks now, including older
revisions, we can remove new-from-rev. While here, reorder the linter
config file, and move the enabled linters up and settings down.
* Fix failing test cases
Studio & Performer export tests use local time rather than UTC. This
fixes the test cases so integration test
passes.
