Peter Lieven 1d8c11d631 ide: add support for IDEBufferedRequest
this patch adds a new aio readv compatible function which copies
all data through a bounce buffer. These buffered requests can be
flagged as orphaned which means that their original callback has
already been invoked and the request has just not been completed
by the backend storage. The bounce buffer guarantees that guest
memory corruption is avoided when such a orphaned request is
completed by the backend at a later stage.

This trick only works for read requests as a write request completed
at a later stage might corrupt data as there is no way to control
if and what data has already been written to the storage.
