As out-of-tree builds are preferred for qemu, running the qemu-iotests
in that out-of-tree build should be supported as well. To do so, a
symbolic link has to be created pointing to the check script in the
source directory. That script will check whether it has been run through
a symlink, and if so, will assume it is run in the build tree. All
output and temporary operations performed by iotests are then redirected
here and, unless specified otherwise by the user, QEMU_PROG etc. will be
set to paths appropriate for the build tree.
Also, drop making every test case executable if it is not yet, as this
would modify the source tree which is not desired for out-of-tree runs
and should be fixed in the repository anyway.

The _rm_test_img() function in common.rc did not quote the image

This adds the VHDX format to the qemu-iotests format, and adds
a read test. The test reads from an existing sample image, that
was created with Hyper-V under Windwos Server 2012.
The image file is a 1GB dynamic image, with 32MB blocks.
The pattern 0xa5 exists from 0MB-33MB (past a block size boundary)
The pattern 0x96 exists from 33MB-66MB (past another block boundary,
and leaving a partial blank block)
From 66MB-1024MB, all reads should return 0.
Although 1GB dynamic image with 66MB of data, the bzip2'ed image
file size is only 874 bytes.
This also adds in the IMGFMT_GENERIC flag, so r/o images can be
tested (e.g. ./check -vhdx) without failing tests that assume
r/w support.

In _img_info, filter out additional information specific to the image
format provided by qemu-img info, since tests designed for multiple
image formats would produce different outputs for every image format
otherwise.
In a human-readable dump, that new information will always be last for
each "image information block" (multiple blocks are emitted when
inspecting the backing file chain). Every block is separated by an empty
line. Therefore, in this case, everything starting with the line "Format
specific information:" up to that empty line (or EOF, if it is the last
block) has to be stripped.
The JSON dump will always emit pretty JSON data. Therefore, the opening
and closing braces of every object will be on lines which are indented
by exactly the same amount, and all lines in between will have more
indentation. Thus, in this case, everything starting with a line
matching the regular expression /^ *"format-specific": {/ until /^ *},?/
has to be stripped, where the number of spaces at the beginning of the
respective lines is equal.

For image formats that are not "QEMU native", but supported for
compatibility, it is useful to verify that an image created with
the 'gold standard' native tool can be read / written to successfully
by QEMU.
In addition to testing non-native images, this could also be useful to
test against image files created by older versions of QEMU.
This provides a directory to store small sample images, for use by
scripts in tests/qemu-iotests.
Image files should be compressed with bzip2.
To use a sample image from a bash script, the _use_sample_img function
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
be the decompressed sample image copy. To cleanup, call
_cleanup_test_img as normal.

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).
