qemu-iotests: filter QEMU_PROG in 051.out

Filter the name of the QEMU executable so the output can be diffed no
matter what QEMU_PROG is (e.g. qemu-system-x86_64).

ide: refuse WIN_READ_NATIVE_MAX on empty device

What is the highest addressable sector on an empty CD-ROM? Nothing is
addressable so produce an error.

This patch prevents a divide-by-zero in ide_set_sector() since
s->sectors and s->heads would be 0. Not to mention that a sector=-1...

block: Add support for Secure Shell (ssh) block device.

qemu-system-x86_64 -drive file=ssh://hostname/some/image

QEMU will ssh into 'hostname' and open '/some/image' which is made
available as a standard block device.

You can specify a username (ssh://user@host/...) and/or a port number...

block: ssh: Use libssh2_sftp_fsync (if supported by libssh2) to flush to disk.

libssh2_sftp_fsync is an extension to libssh2 to support fsync(2) over
sftp, which is itself an extension of OpenSSH.

If both libssh2 and the ssh daemon support it, this will allow...

iotests: Add 'check -ssh' option to test Secure Shell block device.

Note in order to run these tests on ssh, you must be running a local
ssh daemon, and that daemon must accept loopback connections, and
ssh-agent has to be set up to allow logins on the local daemon. In...

rbd: add an asynchronous flush

The existing bdrv_co_flush_to_disk implementation uses rbd_flush(),
which is sychronous and causes the main qemu thread to block until it
is complete. This results in unresponsiveness and extra latency for
the guest.

Fix this by using an asynchronous version of flush. This was added to...

savevm: Implement block_writev_buffer()

Instead of breaking up RAM state into many small chunks, pass the iovec
to the block layer for better performance.
