Alexey Perevalov 65ace06045 migration: add postcopy total blocktime into query-migrate 
Postcopy total blocktime is available on destination side only.
But query-migrate was possible only for source. This patch
adds ability to call query-migrate on destination.
To be able to see postcopy blocktime, need to request postcopy-blocktime
capability.

The query-migrate command will show following sample result:
{"return":
    "postcopy-vcpu-blocktime": [115, 100],
    "status": "completed",
    "postcopy-blocktime": 100
}}

postcopy_vcpu_blocktime contains list, where the first item is the first
vCPU in QEMU.

This patch has a drawback, it combines states of incoming and
outgoing migration. Ongoing migration state will overwrite incoming
state. Looks like better to separate query-migrate for incoming and
outgoing migration or add parameter to indicate type of migration.

/*
* Notably absent: Proper permission management. This is sad, but it seems
* almost impossible to achieve without changing the semantics and thereby
* limiting the use cases of the qemu-io HMP command.
*
* In an ideal world we would unconditionally create a new BlockBackend for
* qemuio_command(), but we have commands like 'reopen' and want them to
* take effect on the exact BlockBackend whose name the user passed instead
* of just on a temporary copy of it.
*
* Another problem is that deleting the temporary BlockBackend involves
* draining all requests on it first, but some qemu-iotests cases want to
* issue multiple aio_read/write requests and expect them to complete in
* the background while the monitor has already returned.
*
* This is also what prevents us from saving the original permissions and
* restoring them later: We can't revoke permissions until all requests
* have completed, and we don't know when that is nor can we really let
* anything else run before we have revoken them to avoid race conditions.
*
* What happens now is that command() in qemu-io-cmds.c can extend the
* permissions if necessary for the qemu-io command. And they simply stay
* extended, possibly resulting in a read-only guest device keeping write
* permissions. Ugly, but it appears to be the lesser evil.
