* make cgo optional for sqlite

* update go.mod; check error code differently

* reduce api surface even more

* move test errors into sqlite package

* CGO_ENABLED=0 in unit tests

* disable for enterprise, too

* add driver name constant

* remove unused constants

* make test an integration one

* try integration tests without cgo

* implement error codes for modernc sqlite driver

* typo fix

* missing return

* use error pointer as an interface

* alias the driver

* update workspace, check for test errors too

* check error properly

* add missing driver after rebase

* fix missing import after rebase

* debugging, lets try again

* properly parse options, revert many previous changes

* remove another log

* better url parsing

* revert test rename, leave it for later

* revert reusedSession in unistore

* revert more code

* remove driver name

* revert formatting

* add integration test without cgo for sqlite
