makeDirectoryWithParents
Creates a directory and any parent directories that may not exist similar to 'mkdir -p'. If the file system does not support creating directories, this function will fail, setting @error to %G_IO_ERROR_NOT_SUPPORTED. If the directory itself already exists, this function will fail setting @error to %G_IO_ERROR_EXISTS, unlike the similar g_mkdir_with_parents().
For a local #GFile the newly created directories will have the default (current) ownership and permissions of the current process.
If @cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.
Return
true if all directories have been successfully created, false otherwise.
