RH-Commit: [22/50] 10c9be528b9fcfae93f1a12fcd09db1a69e58f64 (peterx/qemu-kvm)

We move there all capabilities helpers from migration.c.

Following David advise:
|
|
- looked through the history, capabilities are newer than 2012, so we
|
|
can remove that bit of the header.
|
|
- This part is posterior to Anthony.
|
|
Original Author is Orit. Once there,
|
|
I put myself. Peter Xu also did quite a bit of work here.
|
|
Anyone else wants/needs to be there? I didn't search too hard
|
|
because nobody asked before to be added.
|
|
|
|
What do you think?
