- don't return random values to the caller
- don't leak fd's.

include sys/param.h for MIN/MAX, needed when building in pkgsrc

soon by X crashing and refusing to start again until the machine is
rebooted, at least in my case.

Implement drmParsePciBusInfo and drmParsePciDeviceInfo.

Uses drmGetBusid for bus info, and pciN with libpci for device info.

Aims to address PR pkg/51795 without needing the kernel changes

confirm before closing any PRs.
