[PATCH v3 0/6] migration: Test the new "file:" migration

[Fabiano Rosas <farosas@suse.de>]

Based-on:
[PATCH V4 0/2] migration file URI
https://lore.kernel.org/r/1688135108-316997-1-git-send-email-steven.sistare@oracle.com

Since v2:

- removed the extra setup event. Libvirt has been enabling events for
  a long time, it should be safe

- fixed small issues pointed out by Peter (leaking memory, mmap args)

- stopped looking at the error string in the QMP error test

- skipped the check for zeroes on non-linux platforms

CI run: https://gitlab.com/farosas/qemu/-/pipelines/917665246

v2:
https://lore.kernel.org/r/20230628165542.17214-1-farosas@suse.de

- added the force-emit-setup-event property
- added verification that the skipped region is empty

CI run: https://gitlab.com/farosas/qemu/-/pipelines/914915941

v1:
https://lore.kernel.org/r/20230626182210.8792-1-farosas@suse.de

Here's the test for the file: migration.

I hit an issue with the setting of migration status. If we call
query-migrate too soon after migrate-incoming, the query returns an
empty response because we're not setting the MIGRATION_STATUS_SETUP in
the incoming path. We just send the event, but never actually change
state.

Aside from the fix, there's some tidying up to avoid duplicating too
much code in the tests.

Thanks
