[PATCH v4 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 v3:

- used FILE_TEST_FILENAME for the three tests

v3:
https://lore.kernel.org/r/20230630212902.19925-1-farosas@suse.de

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

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
