Marco Cavenati 04a191cb36 migration: add FEATURE_SEEKABLE to QIOChannelBlock ...

Enable the use of the mapped-ram migration feature with savevm/loadvm
snapshots by adding the QIO_CHANNEL_FEATURE_SEEKABLE feature to
QIOChannelBlock. Implement io_preadv and io_pwritev methods to provide
positioned I/O capabilities that don't modify the channel's position
pointer.
