Add an improved drmOpenWithType(..) clone which fixes some serious
flaws. Some highlights:
- using busid works only with PCI devices
- open() w/o O_CLOEXEC
- when build w/o udev - it creates a node: mkdir, chown(root), chmod, mknod
- calls back into Xserver/DDX module
- last but no least - borderline hacks with massive documentation [1]
to keep this running.

Why do this in mesa rather than fixing (or adding a new version if
necessary for backwards compatibility) to the libdrm code?
mesa is not the only place that we need to find the node path based on a
driver name to avoid hard coding or putting brittle paths in config files.
There is at least drm_hwcomposer as well for Android and probably others.
(drm_hwc currently uses a hard coded path overridable by a system property):
property_get("hwc.drm.device", path, "/dev/dri/card0");
Regards,
Martin
