This function creates a collection of self-describing refcount
structures (including a new refcount table) at the end of a qcow2 image
file. Optionally, these structures can also describe a number of
additional clusters beyond themselves; this will be important for
preallocated truncation, which will place the data clusters and L2
tables there.
For now, we can use this function to replace the part of
alloc_refcount_block() that grows the refcount table (from which it is
actually derived).

Some tests produce format-dependent output. Either the difference is
filtered out and ignored, or the test case is format-specific so we
don't need to worry about per-format output differences.
There is a third case: the test script is the same for all image formats
and the format-dependent output is relevant. An ugly workaround is to
copy-paste the test into multiple per-format test cases. This
duplicates code and is not maintainable.
This patch allows test cases to add per-format golden output files so a
single test case can work correctly when format-dependent output must be
checked:
123.out.qcow2
123.out.raw
123.out.vmdk
...
This naming scheme is not composable with 123.out.nocache or 123.pc.out,
two other scenarios where output files are split. I don't think it
matters since few test cases need these features.

POSIX says that backslashes in the arguments to 'echo', as well as
any use of 'echo -n' and 'echo -e', are non-portable; it recommends
people should favor 'printf' instead. This is definitely true where
we do not control which shell is running (such as in makefile snippets
or in documentation examples). But even for scripts where we
require bash (and therefore, where echo does what we want by default),
it is still possible to use 'shopt -s xpg_echo' to change bash's
behavior of echo. And setting a good example never hurts when we are
not sure if a snippet will be copied from a bash-only script to a
general shell script (although I don't change the use of non-portable
\e for ESC when we know the running shell is bash).
Replace 'echo -n "..."' with 'printf %s "..."', and 'echo -e "..."'
with 'printf %b "...\n"', with the optimization that the %s/%b
argument can be omitted if the string being printed is a strict
literal with no '%', '$', or '`' (we could technically also make
this optimization when there are $ or `` substitutions but where
we can prove their results will not be problematic, but proving
that such substitutions are safe makes the patch less trivial
compared to just being consistent).
In the qemu-iotests check script, fix unusual shell quoting
that would result in word-splitting if 'date' outputs a space.
In test 051, take an opportunity to shorten the line.
In test 068, get rid of a pointless second invocation of bash.

A user may specify a relative path for accessing qemu, qemu-img, etc.
through environment variables ($QEMU_PROG and friends) or a symlink.
If a test decides to change its working directory, relative paths will
cease to work, however. Work around this by making all of the paths to
programs that should undergo testing absolute. Besides "realpath", we
also have to use "type -p" to support programs in $PATH.
As a side effect, this fixes specifying these programs as symlinks for
out-of-tree builds: Before, you would have to create two symlinks, one
in the build and one in the source tree (the first one for common.config
to find, the second one for the iotest to use). Now it is sufficient to
create one in the build tree because common.config will resolve it.

By default the PBKDF algorithm used with LUKS is tuned
based on the number of iterations to produce 1 second
of running time. This makes running the I/O test with
the LUKS format orders of magnitude slower than with
qcow2/raw formats.
When creating LUKS images, set the iteration time to
a 10ms to reduce the time overhead for LUKS, since
security does not matter in I/O tests.
Previously a full 'check -luks' would take
$ time ./check -luks
Passed all 22 tests
real 23m9.988s
user 21m46.223s

Now it takes

This adds support for using LUKS as an encryption format
with the qcow2 file, using the new encrypt.format parameter
to request "luks" format. e.g.
# qemu-img create --object secret,data=123456,id=sec0 \
-f qcow2 -o encrypt.format=luks,encrypt.key-secret=sec0 \
test.qcow2 10G
The legacy "encryption=on" parameter still results in
creation of the old qcow2 AES format (and is equivalent
to the new 'encryption-format=aes'). e.g. the following are
equivalent:
# qemu-img create --object secret,data=123456,id=sec0 \
-f qcow2 -o encryption=on,encrypt.key-secret=sec0 \
test.qcow2 10G
# qemu-img create --object secret,data=123456,id=sec0 \
-f qcow2 -o encryption-format=aes,encrypt.key-secret=sec0 \
test.qcow2 10G
With the LUKS format it is necessary to store the LUKS
partition header and key material in the QCow2 file. This
data can be many MB in size, so cannot go into the QCow2
header region directly. Thus the spec defines a FDE
(Full Disk Encryption) header extension that specifies
the offset of a set of clusters to hold the FDE headers,
as well as the length of that region. The LUKS header is
thus stored in these extra allocated clusters before the
main image payload.
Aside from all the cryptographic differences implied by
use of the LUKS format, there is one further key difference
between the use of legacy AES and LUKS encryption in qcow2.
For LUKS, the initialiazation vectors are generated using
the host physical sector as the input, rather than the
guest virtual sector. This guarantees unique initialization
vectors for all sectors when qcow2 internal snapshots are
used, thus giving stronger protection against watermarking
attacks.

Historically the qcow & qcow2 image formats supported a property
"encryption=on" to enable their built-in AES encryption. We'll
soon be supporting LUKS for qcow2, so need a more general purpose
way to enable encryption, with a choice of formats.
This introduces an "encrypt.format" option, which will later be
joined by a number of other "encrypt.XXX" options. The use of
a "encrypt." prefix instead of "encrypt-" is done to facilitate
mapping to a nested QAPI schema at later date.
e.g. the preferred syntax is now
qemu-img create -f qcow2 -o encrypt.format=aes demo.qcow2

We document that *file is valid if the return is not an error and
includes BDRV_BLOCK_OFFSET_VALID, but forgot to obey this contract
when a driver (such as blkdebug) lacks a callback. Messed up in
commit 67a0fd2 (v2.6), when we added the file parameter.
Enhance qemu-iotest 177 to cover this, using a sequence that would
print garbage or even SEGV, because it was dererefencing through
uninitialized memory. [The resulting test output shows that we
have less-than-ideal block status from the blkdebug driver, but
that's a separate fix coming up soon.]
Setting *file on all paths that return BDRV_BLOCK_OFFSET_VALID is
enough to fix the crash, but we can go one step further: always
setting *file, even on error, means that a broken caller that
blindly dereferences file without checking for error is now more
likely to get a reliable SEGV instead of randomly acting on garbage,
making it easier to diagnose such buggy callers. Adding an
assertion that file is set where expected doesn't hurt either.

Most callback commands in qemu-io return 0 to keep the interpreter
loop running, or 1 to quit immediately. However, open_f() just
passed through the return value of openfile(), which has different
semantics of returning 0 if a file was opened, or 1 on any failure.
As a result of mixing the return semantics, we are forcing the
qemu-io interpreter to exit early on any failures, which is rather
annoying when some of the failures are obviously trying to give
the user a hint of how to proceed (if we didn't then kill qemu-io
out from under the user's feet):
$ qemu-io
qemu-io> open foo
qemu-io> open foo
file open already, try 'help close'
$ echo $?
0
In general, we WANT openfile() to report failures, since it is the
function used in the form 'qemu-io -c "$something" no_such_file'
for performing one or more -c options on a single file, and it is
not worth attempting $something if the file itself cannot be opened.
So the solution is to fix open_f() to always return 0 (when we are
in interactive mode, even failure to open should not end the
session), and save the return value of openfile() for command line
use in main().
Note, however, that we do have some qemu-iotests that do 'qemu-io
-c "open file" -c "$something"'; such tests will now proceed to
attempt $something whether or not the open succeeded, the same way
as if the two commands had been attempted in interactive mode. As
such, the expected output for those tests has to be modified. But it
also means that it is now possible to use -c close and have a single
qemu-io command line operate on more than one file even without
using interactive mode. Although the '-c open' action is a subtle
change in behavior, remember that qemu-io is for debugging purposes,
so as long as it serves the needs of qemu-iotests while still being
reasonable for interactive use, it should not be a problem that we
are changing tests to the new behavior.
This has been awkward since at least as far back as commit
e3aff4f, in 2009.

When we have a BDS with unallocated clusters, but asking the status
of its underlying bs->file or backing layer encounters an end-of-file
condition, we know that the rest of the unallocated area will read as
zeroes. However, pre-patch, this required two separate calls to
bdrv_get_block_status(), as the first call stops at the point where
the underlying file ends. Thanks to BDRV_BLOCK_EOF, we can now widen
the results of the primary status if the secondary status already
includes BDRV_BLOCK_ZERO.
In turn, this fixes a TODO mentioned in iotest 154, where we can now
see that all sectors in a partial cluster at the end of a file read
as zero when coupling the shorter backing file's status along with our
knowledge that the remaining sectors came from an unallocated cluster.
Also, note that the loop in bdrv_co_get_block_status_above() had an
inefficent exit: in cases where the active layer sets BDRV_BLOCK_ZERO
but does NOT set BDRV_BLOCK_ALLOCATED (namely, where we know we read
zeroes merely because our unallocated clusters lie beyond the backing
file's shorter length), we still ended up probing the backing layer
even though we already had a good answer.

Existing tests do not touch the virtqueue used ring. Instead they poll
the virtqueue ISR register and peek into their request's device-specific
status field.
It turns out that the virtqueue ISR register can be set to 1 more than
once for a single notification (see commit
83d768b564 "virtio: set ISR on dataplane
notifications"). This causes problems for tests that assume a 1:1
correspondence between the ISR being 1 and request completion.
Peeking at device-specific status fields is also problematic if the
device has no field that can be abused for EINPROGRESS polling
semantics. This is the case if all the field's values may be set by the
device; there's no magic constant left for polling.
It's time to process the used ring for completed requests, just like a
real virtio guest driver. This patch adds the necessary APIs.

Sending a break on a serial console can be useful for debugging the
guest. But not all chardev backends support sending breaks (only telnet
and mux do). The chardev-send-break command allows to send a break even
if using other backends.

When qemu is exited, all running jobs should be cancelled successfully.
This adds a test for this for all types of block jobs that currently
exist in qemu.

After _cleanup_qemu(), test cases should be able to start the next qemu
process and call _cleanup_qemu() for that one as well. For this to work
cleanly, we need to improve the cleanup so that the second invocation
doesn't try to kill the qemu instances from the first invocation a
second time (which would result in error messages).

We add the following cross-compile targets:
- mipsel-softmmu,mipsel-linux-user,mips64el-linux-user
- armeb-linux-user
While I was rolling I discovered we could also back out a bunch of the
emdebian hacks as the newly released stretch handles cross compilers
as first class citizens. Unfortunately this also meant I had to drop
the powerpc support as that is no longer in Debian stable.
