This patch adds to the QObject system a method to encode JSON
objects. It also adds printf-like capabilities where you can
write %{a.b} in a format string and the method will walk a
QDict to find the "a" first and "b" in a QDict inside that one
(and then print what's found).
Since QEMU does not have (or I could not find...) a variable-length
string buffer object, I added that to QString, thus making it mutable.
I talked to Luiz and he mentioned that QString were immutable not
by design, but rather due to not having the need so far.
