This takes an array of folders and attaches them together according
to the hierarchy described by their full_names and separator. If
namespace_ is non-%NULL, then it will be ignored as a full_name
prefix, for purposes of comparison. If necessary,
camel_folder_info_build() will create additional #CamelFolderInfo with
%NULL urls to fill in gaps in the tree. The value of short_names
is used in constructing the names of these intermediate folders.
