Hi
In this v8:
- rebase over latests
Please review.
[v7]
- Rebased to last upstream
- Rename the capability to a property. So we move all the problems
that we have on last review dissaper because it is not a capability.
So now, it is works as expected. Enabled for old machine types,
disabled for new machine types. Users will only found it if they go through the migration properties.
Please review.
In this v6:

[v1]
Upstream multifd code synchronize all threads after each RAM section. This is suboptimal.
Change it to only flush after we go trough all ram.
Preserve all semantics for old machine types.
Juan Quintela (3):
multifd: Create property multifd-flush-after-each-section
multifd: Protect multifd_send_sync_main() calls
multifd: Only flush once each full round of memory
