ac9524dc55 qemu-iotests: filter QEMU monitor \r\n
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.

If an explicit driver option is present, but doesn't specify a valid
driver, then bdrv_open() should fail instead of probing the format.

b04b6b6ec3 block: Print its file name if backing file opening failed
If backing file doesn't exist, the error message is confusing and
misleading:

    $ qemu /tmp/a.qcow2
    qemu: could not open disk image /tmp/a.qcow2: Could not open file: No
    such file or directory

But...

    $ ls /tmp/a.qcow2
    /tmp/a.qcow2

    $ qemu-img info /tmp/a.qcow2
    image: /tmp/a.qcow2
    file format: qcow2
    virtual size: 8.0G (8589934592 bytes)
    disk size: 196K
    cluster_size: 65536
    backing file: /tmp/b.qcow2

Because...

    $ ls /tmp/b.qcow2
    ls: cannot access /tmp/b.qcow2: No such file or directory

This is not intuitive. It's better to have the missing file's name in
the error message. With this patch:

    $ qemu-io -c 'read 0 512' /tmp/a.qcow2
    qemu-io: can't open device /tmp/a.qcow2: Could not open backing
    file: Could not open '/stor/vm/arch.raw': No such file or directory
    no file open, try 'help open'

Which is a little bit better.

4f8a066b5f blockdev: Remove IF_* check for read-only blockdev_init
IF_NONE allows read-only, which makes forbidding it in this place
for other types pretty much pointless.

Instead, make sure that all devices for which the check would have
errored out check in their init function that they don't get a read-only
BlockDriverState. This catches even cases where IF_NONE and -device is
used.

2c78857bf6 qemu-iotests: Adjustments due to error propagation
When opening/creating images, propagating errors instead of immediately
emitting them on occurrence results in errors generally being printed on
a single line rather than being split up into multiple ones. This in
turn requires adjustments to some test results.

Also, test 060 used a sed to filter out the test image directory and
format by removing everything from the affected line after a certain
keyword; this now also removes the error message itself, which can be
fixed by using _filter_testdir and _filter_imgfmt.

Finally, _make_test_img in common.rc did not filter out the test image
directory etc. from stderr. This has been fixed through a redirection of
stderr to stdout (which is already done in _check_test_img and
_img_info).

98289620e0 block: Don't parse protocol from file.filename
One of the major reasons for doing something new for -blockdev and
blockdev-add was that the old block layer code parses filenames instead
of just taking them literally. So we should really leave it untouched
when it's passing using the new interfaces (like -drive
file.filename=...).

This allows opening relative file names that contain a colon.
