  migration: convert socket server to QIONetListener

Instead of creating a QIOChannelSocket directly for the migration
server socket, use a QIONetListener. This provides the ability
to listen on multiple sockets at the same time, so enables
full support for IPv4/IPv6 dual stack.

For example,   '$QEMU -incoming tcp::9000' now correctly listens
on both 0.0.0.0 and :: at the same time, instead of only on 0.0.0.0.

  migration: Fix rate limiting issue on RDMA migration

RDMA migration implement save_page function for QEMUFile, but
ram_control_save_page do not increase bytes_xfer. So when doing
RDMA migration, it will use whole bandwidth.

  migration/block: limit the number of parallel I/O requests

the current implementation submits up to 512 I/O requests in parallel
which is much to high especially for a background task.
This patch adds a maximum limit of 16 I/O requests that can
be submitted in parallel to avoid monopolizing the I/O device.

only read_done blocks are in the queued to be flushed to the migration
stream. submitted blocks are still in flight.

  migration: Fix block migration flag case

Fix the case where when a migration with a bad protocol is tried,
we leave the block migration capability set.

(This is a cut down version of my 'migration: Fix block failure cases'
where it's other case was fixed by Peter's dd0ee30caeebbd )
