Currently, qdict_array_split() only splits off entries with a key prefix
of "%u.", packing them into a new QDict. This patch makes it support
entries with the plain key "%u" as well, directly putting them into the
new QList without creating a QDict.
If there is both an entry with a key of "%u" and other entries with keys
prefixed "%u." (for the same index), the function simply terminates.
To do this, this patch also adds a static function which tests whether a
given QDict contains any keys with the given prefix. This is used to test
whether entries with a key prefixed "%u." do exist in the source QDict
without modifying it.

Reversing qdict_array_split(), qdict_flatten() should flatten QLists as
well by interpreting them as QDicts where every entry's key is its
index.
This allows bringing QDicts with QLists from QMP commands to the same
form as they would be given as command-line options, thereby allowing
them to be parsed the same way.

This function splits a QDict consisting of entries prefixed by
incrementally enumerated indices into a QList of QDicts.

Nested QDicts used to be both entered recursively in order to move their
entries to the target QDict and also be moved themselves to the target
QDict like all other objects. This is harmless because for the top
level, qdict_do_flatten() will encounter the (now empty) QDict for a
second time and then delete it, but at the same time it's obviously
unnecessary overhead. Just delete nested QDicts directly after moving
all of their entries.

qdict_flatten(): For each nested QDict with key x, all fields with key y
are moved to this QDict and their key is renamed to "x.y". This operation
is applied recursively for nested QDicts.
