* [10948]: Add changelog entry.
* [10948]: Deprecate the types.DBBackend variable and the NewLevelDB function. Create a NewDB function to replace them.
* [10948]: Add a DBBackend string to the simulation config and a flag for setting it. Update the simulation setup to use that instead of the compile-time DBBackend variable.
* [10948]: Update the mock app creator to use the NewDB function. Not sure what to do about the db backend in that case though.
* [10948]: Update changelog to reflect new db-backend field name.
* [10948]: Use the tendermint db-backend type for the snapshot db.
* [10948]: Update the last use of NewLevelDB by adding a parameter to openDB and uppdating calls to that to provide the db type to use.
* [10948]: Upddate the NewDB function to also have a default db backend type if an empty string is provided there.
* [10948]: Remove the new TODO in mock.NewApp. After looking through it's uses, there doesn't seem to be any desire to change it, and there's no easy way to communicate it.
* [10948]: Enhance the NewDB defer function to also add info to any err that is being returned.
* [10948]: Add some unit tests for NewDB.
* [10948]: Lint fixes.
* [10948]: Add a changelog entry to the deprecated section.
* [10948]: Update the makefile to no longer set the types.DBBackend value.
* [10948]: Use memdb for the mock app instead of goleveldb. I know it was a goleveldb before, but for a mock app, a memdb feels like a better choice (assuming 'mock' and 'mem' mean what I assume they mean).
* [10948]: Fix the store benchmark tests (had some index-out-of-range issues).
* [10948]: Fix cachekv store bench test calling iter.Key() before checking iter.Valid().
* [10948]: Remove the panic recovery from types.NewDB since dbm.NewDB returns an error now (it didn't originally, when NewLevelDB was first written).
* [10948]: Add changlog entry indicationg an API breaking change due to the DBBackend change.
* [10948]: Get rid of the types.NewDB function in favor of just using the tm-db version of it.
* [10948]: Fix Update the codeql-analysis github action to use go v1.17.
* [10948]: Add config file option for the app db backend type.
* [10948]: Adjust the comment on the app-db-backend config entry to clarify fallback behavior.
* [10948]: Add a default of GoLevelDBBackend to GetAppDBBackend. The old DBBackend variable defaulted to that, and some unit tests assume that behavior still exists.
* [10948]: Add the missing quotes around the app-db-backend value.
* [10948]: Small tweak to the changelog's deprecated entry.
* Add the go version declaration back into the codeql-analysis github action.
* [10948]: Update new use of openDB.
* [10948]: Put a brief delay after closing the test network. Hopefully that helps with address-in-use and non-empty directory errors.
