-------------------------------------------

[~xiaochen] mentioned that the pre-commit build for branch-2.8 is broken. Let me resubmit
the patch against the trunk.

> When I call FileContext.rename(src, dst, Options.Rename.OVERWRITE) on a LocalFs (which
extends ChecksumFs), it does not update crc files.
> Every subsequent read on moved files will result in failures due to crc missmatch.
> One solution is to override rename(src, dst, overwrite) the same way it's done with rename(src,
dst) and moving crc files accordingly.
