This virtual block device takes an underlying block device and splits it
into several smaller equal-sized block devices.

a53f617423 bdev: add API to translate to and from NVMe status 
This prevents the need for bdev users and modules to manipulate the
internal bdev_io error.nvme fields.

For now, all non-NVMe error types are treated as a generic device error,
but translation from SCSI to NVMe could be added in the future.

1e85d9ef32 bdev_module.h: move to spdk_internal/bdev.h 
This is consistent with the other internal-only API headers.
