Fix real mode guest migration

Older KVM versions save CS dpl value to an invalid value for real mode guests
(0x3). This patch detect this situation when loading CPU state and set all the
segments dpl to zero.
This will allow migration from older KVM on host without unrestricted guest...

rdma: introduce MIG_STATE_NONE and change MIG_STATE_SETUP state transition

As described in the previous patch, until now, the MIG_STATE_SETUP
state was not really a 'formal' state. It has been used as a 'zero' state
(what we're calling 'NONE' here) and QEMU has been unconditionally transitioning...

rdma: account for the time spent in MIG_STATE_SETUP through QMP

Using the previous patches, we're now able to timestamp the SETUP
state. Once we have this time, let the user know about it in the
schema.

rdma: allow state transitions between other states besides ACTIVE

This patch is in preparation for the next ones: Until now the MIG_STATE_SETUP
state was not really a 'formal' state. It has been used as a 'zero' state
and QEMU has been unconditionally transitioning into this state when...

rdma: core logic

Code that does need to be visible is kept
well contained inside this file and this is the only
new additional file to the entire patch.

This file includes the entire protocol and interfaces
required to perform RDMA migration.

Also, the configure and Makefile modifications to link...

rdma: send pc.ram

This takes advantages of the previous patches:

1. use the new QEMUFileOps hook 'save_page'

2. call out to the right accessor methods to invoke
the iteration hooks defined in QEMUFileOps

rdma: update documentation to reflect new unpin support

As requested, the protocol now includes memory unpinning support.
This has been implemented in a non-optimized manner, in such a way
that one could devise an LRU or other workload-specific information...
