wishlist: support for recursive 'copy' support

[karenetheridge]

Currently, calling $path->copy on a directory results in: copy failed for ... to ...: Is a directory. It would be great to have support for copying directories, as a number of high-river distributions are using a module to do this that may not be suitable for such a high river position.

Possibly File::Copy::Recursive::Reduced could be used for this. There may be alternatives.

I think we should seriously consider writing our own, or putting such functionality into File::Copy. It may be as simple as: use File::Path::mktree to create the directory structure; walk the tree and copy (using File::Copy::copy?) each file from src to dest.

(File::Copy::Recursive uses Path::Tiny (although it really shouldn't), so we simply cannot just use FCR in Path::Tiny to get this functionality.)

This is related to #58 and #22. Directory copies also need to consider a follow_symlinks option. Possibly, in the case of a directory we use the iterator method. As that is breadth first, there's an opportunity to create directories as we go before getting to their children.

This was also posted over at RT as #146593.
