qapi: update the qobject visitor to use QNUM_U64
Switch to use QNum/uint where appropriate to remove i64 limitation. The input visitor will cast i64 input to u64 for compatibility reasons (existing json QMP client already use negative i64 for large u64, and expect an implicit cast in qemu). Note: before the patch, uint64_t values above INT64_MAX are sent over json QMP as negative values, e.g. UINT64_MAX is sent as -1. After the patch, they are sent unmodified. Clearly a bug fix, but we have to consider compatibility issues anyway. libvirt should cope fine, because its parsing of unsigned integers accepts negative values modulo 2^64. There's hope that other clients will, too.
