[PATCH 0/6] More migration improvements

[David Gibson <david@gibson.dropbear.id.au>]

Here's another batch of migration changes.  The first 5 patches are
fixups for fairly minor issues in the existing draft patches.  It
probably makes sense to fold them into the existing patches.

The last one changes the structure of the migration callbacks /
sections with a new scheme that's simpler and more flexible.
Specifically it will allow callbacks which "stream" data in a format
designed for migration rather than being identical to the in memory
structure.

David Gibson (6):
  vhost-user: Change different vhost-user messages to trace() level
  migrate, flow: Abort migration on repair_flush() failure
  migrate: Clearer debug message in migrate_request()
  migrate: Handle sending header section from data sections
  util: read_remainder should take const pointer to iovec
  migrate: Make migration handlers simpler and more flexible
