Include symlink destination in path info.

[rcfox]

What do these changes do?

The existing parse_list_line_unix function goes to all the work of parsing symlink lines, but omits the actual destination of the symlink. This tiny change adds the parsed destination to the path's info dictionary.

Are there changes in behavior for the user?

One extra key is included in the info dict when issuing a LIST command to a unix server.

FTP protocol have nothing about link type. It is just internal part of current implementation. If you need all this information, you should use parse_list_line_custom and use your own parse code or copy-paste existing one with your fixes.

+1 for this change.
As of now the size reported by the stat is a link file size, but not a link target size.

With current implementation there is no way to know if the size is valid.
