[Qemu-devel] [PULL 04/32] qapi: Use qemu_strtod_finite() in qobject-input-visitor

[Markus Armbruster <armbru@redhat.com>]

From: David Hildenbrand <david@redhat.com>

Let's use the new function. Just as current behavior, we have to
consume the whole string (now it's just way clearer what's going on).
