This adds tests for live snapshots, both through the single
snapshot command, and the transaction group snapshot command.
The snapshots are done through the QMP interface, using the
following commands for snapshots:
Single snapshot:
{ 'execute': 'blockdev-snapshot-sync', 'arguments':
{ 'device': 'virtio0', 'snapshot-file':'...',
'format': 'qcow2' } }"
Group snapshot:
{ 'execute': 'transaction', 'arguments':
{'actions': [
{ 'type': 'blockdev-snapshot-sync', 'data' :
{ 'device': 'virtio0', 'snapshot-file': '...' } },
{ 'type': 'blockdev-snapshot-sync', 'data' :
{ 'device': 'virtio1', 'snapshot-file': '...' } } ]
} }

Using an invalid option for a block device that is opened with

The 071 test is designed for IMGFMT=qcow2 because it uses the l2_load
blkdebug event. Its output filtering also assumes that IMGFMT is not
raw since 071.out contains "format=raw" but IMGFMT=raw would filter the
output to "format=IMGFMT".
Perhaps the test case can be rewritten to be more generic, but for now
let's document that it was only supposed to work with qcow2.

This test is not written in Python, although it uses QMP. This is
because it invokes the qemu-io HMP command, which outputs errors to

output is easier in a shell script than with the Python infrastructure.

It should be possible to use a format as a driver for a file which in
turn requires another file, i.e., nesting file formats.
Allowing nested file formats results in e.g. qcow2 BlockDriverStates
never being directly passed to bdrv_open_common() from bdrv_file_open(),
but instead being handed through bdrv_open(). This changes the error
message when trying to give a filename to qcow2, i.e. trying to use it
as a driver for the protocol level. Therefore, change the reference
output of I/O test 051 accordingly.

SMTP does not preserve newlines. This is normally not a problem if the
email body uses DOS or UNIX newlines consistently. In 051.out we mix
UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n).
This patch filters the QEMU monitor output so the golden master file
uses UNIX newlines exclusively.
The result is that patches touching 051.out will apply cleanly without
mangling newlines after this commit.
