* Enforce file permissions in case they've changed
* test behaviour for autofile
* use testify in tests and rename `fInf` to `fileInfo`
* return an error if file permissions have changed
- if we can't read the file, we'll still panic
* get rid of "github.com/pkg/errors" dependency
* address review comments:
- prefix instead of suffix
- add state to err and construct formatting in Error() method
* address review comments:
- move error to libs/errors
+ *FSDB.HasKey now uses common.FileExists to test for file existence
+ IsKeyInDomain takes key as a []byte slice instead of as a string
to avoid extraneous []byte<-->string conversions for start and end
+ Iterator.Close() instead of Iterator.Release()
+ withDB helper to encapsulate DB creation, deferred cleanups
so that for loops can use opened DBs and discard them ASAP
