668e3cac4f qjson: Improve debugging
Add an assert() to qobject_from_jsonf() to assure that the returned
QObject is not NULL. Currently this is duplicated in the callers.

ff06ea2197 json: escape u0000 .. u001F when outputting json
Markus Armbruster pointed out:

JSON requires control characters in strings to be escaped.  RFC 4627
section 2.5:

   A string begins and ends with quotation marks.  All Unicode
   characters may be placed within the quotation marks except for the
   characters that must be escaped: quotation mark, reverse solidus, and
   the control characters (U+0000 through U+001F).

We've been quoting the special escape sequences that JSON defines but we
haven't been encoding the full control character range.  This patch fixes that.

8ff5a7d346 QJSON: Introduce qobject_from_jsonv()
It accepts a va_list and will be used by QError. Also simplifies
the code a little, as the other qobject_from_() functions can
use it.
