Thiago Macieira 0c355e78f0 QRandomGenerator: add support for hardware-based random generators
This commit adds support for the x86 RDRAND instruction for
QRandomGenerator. This is the same that libstdc++-v3 uses for
std::random_device() by default. If it fails because the hardware does
not have enough entropy collected, we fall back to the operating system
generator, which often has more entropy collected from other sources.
