v2:
- Patch "migration: Provide explicit error message for file shutdowns"
- Touched up qapi doc [Fabiano]
- Added Bugzilla link to commit which I didn't even notice that I was
fixing a bug.. but rightfully pointed out by Laszlo.
- Moved it to the 1st patch because it fixes a bug, please consider
review and merge it earlier.
This is a small series that reworks error handling of postcopy return path
threads.
We used to contain a bunch of error_report(), converting them into
error_setg() properly and deliver any of those errors to migration generic
error reports (via migrate_set_error()). Then these errors can also be
observed in query-migrate after postcopy is paused.
Dropped the return-path specific error reporting: mark_source_rp_bad(),
because it's a duplication if we can always use migrate_set_error().
Please have a look, thanks.

migration: Introduce migrate_has_error()
migration: Refactor error handling in source return path
migration: Deliver return path file error to migrate state too
qemufile: Always return a verbose error
