The table of bdev function pointers should not need to be modified at
runtime.

If a bdev doesn't need to be polled, allow it to specify NULL for the
check_io function pointer to indicate that no poller needs to be
registered.
This will be useful for virtual blockdevs that don't have any associated
hardware to poll.

It is always a spdk_bdev_io pointer, so avoid the need for casting back
and forth between that and a void pointer.

This callback was only used for freeing buffers, but the buffers are now
managed by the bdev core, so none of the free_request callbacks actually
do anything.

Bdev modules need a separate interface than public
consumers of the blockdevs.

Some block devices do not support the unmap operation, and we may add
other optional I/O types in the future. Add a method to check which I/O
types a specific block device supports.

This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).
It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.

This is the size of a logical block in bytes; 4 GB is more than plenty.
Also allows cleaning up casts to uint32_t in the SCSI translation layer.

Combine the necessary functionality with the main bdev file.
