[PATCH v3 0/2] 9pfs: test suite fixes

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

Fixes test failures with the 9pfs 'local' tests as discussed with latest
9P PR. See the discussion of that PR v2 (Fri, Oct 30th) for details.

In conjunction with Peter Xu's two migration patches (fixing occasional
lockups of migration tests) overall situation appears to be smooth now:
https://lore.kernel.org/qemu-devel/20201030135350.GA588069@xz-x1/

v2->v3:

  - Make the two functions for creating and removing the 9pfs test directory
    public [NEW patch 1].

  - Place the constructor and destructor functions in virtio-9p-test.c, not
    in virtio-9p.c, because the latter location would cause the constructor
    to be executed whenever libqos is loaded, which would break other,
    completely unrelated tests suites that just link to libqos [patch 2].

  - Previous patch 2 (coverity fix) is already queued, no changes, hence
    omitted in this v3.

v1->v2:

  - Added Greg's tested-by tag [patch 1].

  - Log an info-level message if mkdir() failed [patch 2].

  - Update commit log message about coverity being the reporter and
    details of the coverity report [patch 2].
