Bug Description

It would be better if innobackupex has a --force to copy/move the
files. It helps in some cases as discussed over irc.

Re. #2,

While issues in #1193240 have been addressed elswhere, the issue here will need to be fixed in innobackupex itself.

As I understand, the goal here is to implement an option to force --copy-back or --move-back to transfer files to directories, even if they are not empty. Overwriting existing _files_ in those directories should still be disallowed. That is, target directories for --copy-back/--move-back may contain other (temporary) subdirectories or files, which will never conflict with files being copied from the backup directory.

If that's correct, I'm going to implement the --force-non-empty-directories option. When specified, it will make --copy-back/--move-back skip the "empty directory" checks.

summary: - move-back/copy-back can do with force in some cases
+ move-back/copy-back should allow non-empty directories in some cases
