In cases where a rename fails the fileutil.Replace would delete the
source files/folder.
There is no easy way to make directory renaming atomic, but for files
os.Rename is atomic and replaced the destination file so there is no
need to remove the destination file explicitly.

new verifications, hence some clean up in the code.

implement a `CopyDirs` helper to walk all dirs and subdirs and copy all files within to a destination folder.
Refactor `TestRepairBadIndexVersion` to use the `CopyDirs` so it works on a copy db and remove the copy after the test.
This allows running the test more than once and doesn't confuse git.

Create checkpoints from a sequence of WAL segments while filtering
out obsolete data. The checkpoint format is again a sequence of WAL
segments, which allows us to reuse the serialization format and
implementation.
