spdk_bdev_create_bs_dev_ext() gets not bdev pointer but bdev name
as an argument, and hence vbdev_lvs_create() will get bdev name
accordingly.
However after completing spdk_bdev_create_bs_dev_ext(),
vbdev_lvs_create() has to get bdev pointer from the created bs_dev.
Hence add a function pointer get_base_bdev to struct spdk_bs_dev
and set it to bdev_blob_get_base_bdev() at initialization.

spdk_bdev_open_ext() requires the caller to use bdev_event_cb_t
and bdev_event_cb_t is more extensible than bdev_remove_cb_t.
Hence use bdev_event_t as an argument.
spdk_bdev_open_ext() calls spdk_bdev_get_by_name() inside and
spdk_bdev_create_bs_dev_ext() calls spdk_bdev_open_ext() inside.
The caller needs to know if the spdk_bdev_get_by_name() succeeded.
Hence spdk_bdev_create_bs_dev_ext() returns return code by return
value and returns the created bs_dev by double pointer.

New interface for create spdk_bs_dev from bdev desc.
This change, together with spdk_bdev_open_ext, can
remove the race condition where user gets the bdev
structure, but bdev is removed after getting that
structure and before spdk_bdev_create_bs_dev function
is called.
