[Qemu-devel] [PATCH resend 0/6 RFC] Provide common methods for exchange FD

[Lei Li <lilei@linux.vnet.ibm.com>]

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.
