efa06a2bab bdev: remove free_request bdev backend function
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.

6e09a48e42 bdev: Separate the module header from the public header
Bdev modules need a separate interface than public
consumers of the blockdevs.

9272088d93 bdev: add API to query supported I/O types
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.

5d8c94536a event: hide struct spdk_poller internals
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.

040c0193f4 bdev: change blocklen from uint64_t to uint32_t
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.
