We are planning to add more block export types than just NBD in the near
future (e.g. vhost-user-blk and FUSE). This series lays the ground for
this with some generic block export infrastructure and QAPI interfaces
that will allow managing all of them (for now add/remove/query).
As a side effect, qemu-storage-daemon can now map --export directly to
the block-export-add QMP command, similar to other command line options.
The built-in NBD servers also gains new options that bring it at least a
little closer to feature parity with qemu-nbd.
