Finally, copy-before-write gets own .bdrv_open and .bdrv_close
handlers, block_init() call and becomes available through bdrv_open().
To achieve this:
- cbw_init gets unused flags argument and becomes cbw_open
- block_copy_state_free() call moved to new cbw_close()
- in bdrv_cbw_append:
- options are completed with driver and node-name, and we can simply
use bdrv_insert_node() to do both open and drained replacing
- in bdrv_cbw_drop:
- cbw_close() is now responsible for freeing s->bcs, so don't do it

Use bdrv_new_open_driver_opts() instead of complicated bdrv_open().
Among other extra things bdrv_open() also check for white-listed
formats, which we don't want for internal node creation: currently
backup doesn't work when copy-before-write filter is not white-listed.
As well block-stream doesn't work when copy-on-read is not
white-listed.
