Subject: [PATCH v2 0/8] tools/vhost: Reset virtqueue on tests

This series add tests used to validate the "vhost: Reset batched
descriptors on SET_VRING_BASE call" series, with a few minor updates of
them.

They are based on the tests sent back them, the ones that were not
included (reasons in that thread). This series changes:

* Delete need to export the ugly function in virtio_ring, now all the
code is added in tools/virtio (except the one line fix).
* Add forgotten uses of vhost_vq_set_backend. Fix bad usage order in
vhost_test_set_backend.
* Drop random reset, not really needed.
* Minor changes.

This patchset commit messages contains references to commits under
"for_linus" tag and references to commits in for_linus..mst/vhost.
They are fixes, so probably it is better just to squash if possible:

("7c48601a3d4d tools/virtio: Add --reset=random"): Already in for_linus
("af3756cfed9a vhost: batching fetches"): Only in vhost branch, not in
for_linus.

Thanks!

Changes from v1:
* Different base, since branch was force-pushed.
* Using new vring_legacy_*, as base uses them now.

This serie is meant to be applied on top of
