KVM selftests changes for 7.3, part 2 - Fix several issues with seeding KVM's pRNG, and rework the pRNG APIs to that the pRNG can be sanely used in host code, not just guest code. - Add an IRQ test to validate virtual IRQ deliverty for IRQs wired up via KVM_IRQFD + KVM_SET_GSI_ROUTING, with optional support for triggering IRQs via writes to an assigned VFIO device. - Add syscall wrappers to assert success on a variety of pthreads and CPU affinity APIs. - Set vCPU pthread affinity as early as possible to reduce contention issues that were surfaced by PREEMPT_LAZY, which result in runtimes of over a minute on large hosts, versus the expected ~5 seconds. - Rework the PMU counters test to run each testcase using a single VM with many vCPUs for each sub-testcase, instead of using a unique VM for each sub-testcase. This cuts the runtime by ~20x.
