[PATCH v1 0/5] vhost-user-blk: dynamically resize config space based on features |

This patch set attempts to align vhost-user-blk with virtio-blk in
terms of backward compatibility and flexibility.
In particular it adds the following things:
- Ability to disable modern features like discard/write-zeroes.
- Dynamic configuration space resizing based on enabled features,
by reusing the code, which was already present in virtio-blk.
- Makes the VHostUserBlk structure a bit less clunky by using the
'host_features' field to represent enabled features, as opposed to
using a separate field per feature. This was already done for
virtio-blk a long time ago.
Daniil Tatianin (5):
virtio-blk: decouple config size determination code from VirtIOBlock
virtio-blk: move config space sizing code to virtio-blk-common
vhost-user-blk: make it possible to disable write-zeroes/discard
vhost-user-blk: make 'config_wce' part of 'host_features'
vhost-user-blk: dynamically resize config space based on features
