Currently, paddle/utils includes miscellaneous, irrelevant source code, which should be deleted or moved to other places.

For instance, dependency relationships:

[utils <- cuda], [cuda <- utils] initMain() in utils dir depends on hl_start() in cuda dir, and vice versa .

After discussing with @reyoung @wangkuiyi, we reached a preliminary consensus to revise sources.
