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.

The drive-backup command is similar to the drive-mirror command, except
no guest data written after the command executes gets copied. Add a
sync mode argument which determines whether the entire disk is copied,
just allocated clusters, or only clusters being written to by the guest.
Currently only sync mode 'full' is supported - it copies the entire disk.
For read-only point-in-time snapshots we may only need sync mode 'none'
since the target can be a qcow2 file using the guest's disk as its
backing file (no need to copy the entire disk). Finally, sync mode
'top' is useful if we wish to preserve the backing chain.
Note that this patch just adds the sync mode argument to drive-backup.
It does not implement sync modes 'top' or 'none'. This patch is
necessary so we can add a drive-backup HMP command that behaves like the
existing drive-mirror HMP command and takes a sync mode.

bd07684aac added a test to ensure BSY
flag is set when a flush request is in flight. It does this by setting
a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE.
It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset.
The actual unsetting of BSY does not occur until ide_flush_cb gets
called in a bh, however, so in some cases this check will race with
the actual completion.
Fix this by polling the ide status register until BSY flag gets unset
before we do our final sanity checks. According to
f68ec8379e this is in line with how a guest
would determine whether or not the device is still busy.

With the introduction of native list types, we now have types such as
int64List where the 'value' field is not a pointer, but the actual
64-bit value.
On 32-bit architectures, this can lead to situations where 'next' field
offset in GenericList does not correspond to the 'next' field in the
types that we cast to GenericList when using the visit_next_list()
interface, causing issues when we attempt to traverse linked list
structures of these types.
To fix this, pad the 'value' field of GenericList and other
schema-defined/native *List types out to 64-bits.
This is less memory-efficient for 32-bit architectures, but allows us to
continue to rely on list-handling interfaces that target GenericList to
simply visitor implementations.
In the future we can improve efficiency by defaulting to using native C
array backends to handle list of non-pointer types, which would be more
memory efficient in itself and allow us to roll back this change.

Known bugs in to_json():
* A start byte for a three-byte sequence followed by less than two
continuation bytes is split into one-byte sequences.
* Start bytes for sequences longer than three bytes get misinterpreted
as start bytes for three-byte sequences. Continuation bytes beyond
byte three become one-byte sequences.
This means all characters outside the BMP are decoded incorrectly.
* One-byte sequences with the MSB are put into the JSON string
verbatim when char is unsigned, producing invalid UTF-8. When char
is signed, they're replaced by "\\uFFFF" instead.
This includes \xFE, \xFF, and stray continuation bytes.
* Overlong sequences are happily accepted, unless screwed up by the
bugs above.
* Likewise, sequences encoding surrogate code points or noncharacters.
* Unlike other control characters, ASCII DEL is not escaped. Except
in overlong encodings.
My rewrite fixes them as follows:
* Malformed UTF-8 sequences are replaced.
Except the overlong encoding \xC0\x80 of U+0000 is still accepted.
Permits embedding NUL characters in C strings. This trick is known
as "Modified UTF-8".
* Sequences encoding code points beyond Unicode range are replaced.
* Sequences encoding code points beyond the BMP produce a surrogate
pair.
* Sequences encoding surrogate code points are replaced.
* Sequences encoding noncharacters are replaced.
* ASCII DEL is now always escaped.

The gthread coroutine backend is broken and does not produce a working
QEMU; it is only useful for some very limited debugging situations.
Clean up the backend selection logic in configure so that it now runs
"if on windows use windows; else prefer ucontext; else sigaltstack".
To do this we refactor the configure code to separate out "test
whether we have a working ucontext", "pick a default if user didn't
specify" and "validate that user didn't specify something invalid",
rather than having all three of these run together. We also simplify
the Makefile logic so it just links in the backend the configure
script selects.

Instead of just checking once in exactly this order if there are
dependendies, non-COW clusters and new allocation, this starts looping
around these. This way we can, for example, gather non-COW clusters after
new allocations as long as the host cluster offsets stay contiguous.
Once handle_dependencies() is extended so that COW areas of in-flight
allocations can be overwritten, this allows to continue with gathering
other clusters (we wouldn't be able to do that without this change
because we would have missed a possible second dependency in one of the
next clusters).
This means that in the typical sequential write case, we can combine the
COW overwrite of one cluster with the allocation of the next cluster as
soon as something like Delayed COW gets actually implemented. It is only
by avoiding splitting requests this way that Delayed COW actually starts
improving performance noticably.

This should be based on the virtual disk size, not on the size of the
image.
Interesting observation: With some VM state stored in the image file,
percentages higher than 100% are possible, even though snapshots
themselves are ignored. This is a qcow2 bug to be fixed another day: The
VM state should be discarded in the active L2 tables after completing
the snapshot creation.

A comment explains that -nographic hangs test case 007. This is no
longer the case so add -nographic. This makes the test suite faster and
more pleasant to run since no windows pop up.
I am not sure exactly when -nographic starting working for this case but
there is no fundamental reason why graphics are needed here. Make sure
the serial port is not on stdio, it would conflict with the monitor.
Also remove unnecessary trailing whitespace on these lines.

If zero clusters are erroneously treated as unallocated, "qemu-img rebase"
will copy the backing file's contents onto the cluster.
The bug existed also in image streaming, but since the root cause was in
qcow2's is_allocated implementation it is enough to test it with qemu-img.

Now that each AioContext has a ThreadPool and the main loop AioContext
can be fetched with bdrv_get_aio_context(), we can eliminate the concept
of a global thread pool from thread-pool.c.
The submit functions must take a ThreadPool* argument.
block/raw-posix.c and block/raw-win32.c use
aio_get_thread_pool(bdrv_get_aio_context(bs)) to fetch the main loop's
ThreadPool.
tests/test-thread-pool.c must be updated to reflect the new
thread_pool_submit() function prototypes.

As of glib 2.35.4, glib changed its logic for ordering test cases:
https://bugzilla.gnome.org/show_bug.cgi?id=694487
This was causing failures in rtc-test. Group the reordered test
cases into their own suite, which maintains the original ordering.

The previous implementation incorrectly used same macro to detect overflow
for addition and subtraction. This patch makes distinction between these
two, and creates separate macros. The affected routines are changed
accordingly.
This change also includes additions to the existing tests for SUBQ_S_PH and
SUBQ_S_W that would trigger the fixed issue, and it removes dead code from
the test file. The last test case in subq_s_w.c is a bug found/reported/
isolated by Klaus Peichl from Dolby.
