qmp_output_get_qobject() increments the qobject's reference count. Since
we currently pass this straight into qobject_to_json() so we can feed
the data into a QMP input visitor, we never actually free the underlying
qobject when qmp_output_visitor_cleanup() is called. This causes leaks
on all of the QMP serialization tests.
Fix this by holding a pointer to the qobject and decref'ing it before
returning from qmp_deserialize().

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 replacement character is U+FFFD.

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.
