The destination registers of SIMD signed compare instructions
(fcmp*<16|32>) are not FP registers but general purpose r registers.
Comparisons should be freg_rs1 CMP freg_rs2, that were reversed.

Spice worker does no longer process commands when it is stopped.
Otherwise, it might crash during migration when attempting to process
commands while the guest is not completely loaded.

In snapshotting there is no guest involved, so we can safely use a writeback
mode and do the flushes in the right place (i.e. at the very end). This
improves the time that creating/restoring an internal snapshot takes with an
image in writethrough mode.

qemu-img.c wants to count allocated file size of image. Previously it
counts a single bs->file by 'stat' or Window API. As VMDK introduces
multiple file support, the operation becomes format specific with
platform specific meanwhile.
The functions are moved to block/raw-{posix,win32}.c and qemu-img.c calls
bdrv_get_allocated_file_size to count the bs. And also added VMDK code
to count his own extents.

The return type of get_cluster_offset was an offset that use 0 to denote
'not allocated', this will be no longer true for flat extents, as we see
flat extent file as a single huge cluster whose offset is 0 and length
is the whole file length.
So now we use int return value, 0 means success and otherwise offset
invalid.

'tag' is just an abstraction to identify the command
from the driver. So we should make that explicit by
replacing 'tag' with a driver-defined pointer 'hba_private'.
This saves the lookup for driver handling several commands
in parallel.
'tag' is still being kept for tracing purposes.

A host chardev could close just before the guest sends some data to be
written. This will cause an -EPIPE error. This shouldn't be propagated
to virtio-serial-bus.
Ideally we should close the port once -EPIPE is received, but since the
chardev interface doesn't return such meaningful values to its users,
all we get is -1 for any kind of error. Just return 0 for now and wait
for chardevs to return better error messages to act better on the return
messages.
