Before, it used type 's', which strips quotes and interprets escapes,
and is quite inappropriate for QMP.

Negative arguments are no flushed to zero.  Before, they were cast to
uint32_t, which wrecked the sign.

Ridiculously large arguments including infinities are now rejected.
Before, they were interpreted as zero.  Same for NaN.
