Add a new function, drmOpenRender, that can be used to open render nodes. This
can be used in the same way that drmOpenControl is used to open control nodes.

Now that there are render nodes it doesn't seem appropriate for the type of
the card nodes to be DRM_NODE_RENDER. For this reason, rename this type to
DRM_NODE_PRIMARY as this name better represents the purpose of these nodes.

drmOpenByName() is a static function that is only called by drmOpen().
drmOpen() already checks drmAvailable(), so the check in
drmOpenByName() is redundant.

The debug message's format string doesn't contain any conversion
specifiers, therefore making the fd argument unused.

These functions all take a format string and either a list of variable
arguments or a va_list. Use the new DRM_PRINTFLIKE macro to tell the
compiler about it so that the arguments can be checked against the
format string.

If clock_gettime did fail, it would return -1 and set errno.
What we really want to strerror() is the errno.

These are just basic ioctl wrappers around the prime ioctls,
along with the capability reporting.

_DRM_MALLOC hasn't been a relevant concern since we split libdrm out
from xserver.

This works in conjunction with newer kernels. If we succeed in requesting
interface 1.4, the we know the kernel provides proper domain numbers. If
not, ignore the domain number as it's bogus (except on Alpha).

DRM_MAJOR is platform specific, but not used outside of xf86drm.c
that I can find.

Determines the /dev filename of the drm fd argument.
