0f95673d82 bdev/split: use "offset_blocks" in JSON config
This is consistent with the rest of the RPC calls that report a number
of blocks, and it matches the field in the split_disk structure.

7829c5ec9c bdev/split: add driver name to driver_specific JSON
The driver_specific object should contain a single object with the
blockdev driver's name so that the user can determine how to interpret
it.  This matches the NVMe blockdev driver.

9b38556afe bdev/split: pass correct bdev to base_bdev functions
Since the io_channel will be passed to the underlying bdev's
read/write/... functions later, we need to also acquire an io_channel
for the underlying bdev, not for the virtual bdev.

2c0bc38754 bdev: add "split" virtual blockdev example
This virtual block device takes an underlying block device and splits it
into several smaller equal-sized block devices.
