This patch series tries to refactor the functions used for exchange of FD in current code, provide common methods for it.
The series is based on the localhost migration with side channel for ram series as it was already a good shape. But if you want to merge this first, I'll get rid of the migration part. I just tested page flipping migration, and tap/bridge-helper a bit, but have some environment problem on proxy fs driver. So it'd be appreciated if someone could help on verifying whether it has impact on it. :) Please let me know if there is anything needs to be improved. Thanks.
