P1: Replaces the old per-ioctl C handlers with a unified dispatch through\nredox_drm_simple_ioctl(), adds VirtGPU NR mappings (MAP, EXECBUFFER,\nGETPARAM, RESOURCE_CREATE, GET_CAPS, etc.), and special handlers for\nEXECBUFFER (inline command buffer) and GET_CAPS (variable response). P2: Adds __redox__ blocks to drmParsePciBusInfo, drmParsePciDeviceInfo,\nand drmGetDevice2 using the DRM scheme GET_PCI_INFO ioctl to populate\nPCI device identification without /sys access.
