* Copy offloading for qemu-img convert (iSCSI, raw, and qcow2)
If the underlying storage supports copy offloading, qemu-img convert will
use it instead of performing reads and writes. This avoids data transfers
and thus frees up storage bandwidth for other purposes. SCSI EXTENDED COPY

It does not get the RDMA_CM_EVENT_DISCONNECTED event after rdma_disconnect sometime.
According to IB Spec once active side send DREQ message, it should wait for DREP message
and only once it arrived it should trigger a DISCONNECT event. DREP message can be dropped
due to network issues.
For that case the spec defines a DREP_timeout state in the CM state machine, if the DREP is
dropped we should get a timeout and a TIMEWAIT_EXIT event will be trigger.
Unfortunately the current kernel CM implementation doesn't include the DREP_timeout state
and in above scenario we will not get DISCONNECT or TIMEWAIT_EXIT events.
So it should not invoke rdma_get_cm_event which may hang forever, and the event channel
is also destroyed in qemu_rdma_cleanup.

migration: Don't activate block devices if using -S
Activating the block devices causes the locks to be taken on
the backing file. If we're running with -S and the destination libvirt
hasn't started the destination with 'cont', it's expecting the locks are
still untaken.
Don't activate the block devices if we're not going to autostart the VM;
'cont' already will do that anyway. This change is tied to the new
migration capability 'late-block-activate' that defaults to off, keeping
the old behaviour by default.

migration: discard non-migratable RAMBlocks
On the POWER9 processor, the XIVE interrupt controller can control
interrupt sources using MMIO to trigger events, to EOI or to turn off
the sources. Priority management and interrupt acknowledgment is also
controlled by MMIO in the presenter sub-engine.
These MMIO regions are exposed to guests in QEMU with a set of 'ram
device' memory mappings, similarly to VFIO, and the VMAs are populated
dynamically with the appropriate pages using a fault handler.
But, these regions are an issue for migration. We need to discard the
associated RAMBlocks from the RAM state on the source VM and let the
destination VM rebuild the memory mappings on the new host in the
post_load() operation just before resuming the system.
To achieve this goal, the following introduces a new RAMBlock flag
RAM_MIGRATABLE which is updated in the vmstate_register_ram() and
vmstate_unregister_ram() routines. This flag is then used by the
migration to identify RAMBlocks to discard on the source. Some checks
are also performed on the destination to make sure nothing invalid was
sent.
This change impacts the boston, malta and jazz mips boards for which
migration compatibility is broken.

The idea of the optimization was to avoid ping-pongs between threads by
keeping the Big QEMU Lock held across non-blocking (!timeout) main loop
iterations.
A warning is printed when the main loop spins without releasing BQL for
long periods of time. These warnings were supposed to aid debugging but
in practice they just alarm users. They are considered noise because
the cause of spinning is not shown and is hard to find.
Now that the lock optimization has been removed, there is no danger of
hogging the BQL. Drop the spin counter and the infamous warning.

OPOST flag in c_oflag enables output processing letting other flags in

causes crlf to be sent in place of lf. This breaks binary transmissions.
Unsetting OPOST flag turns off any output processing which fixes the bug.
