Currently most places assume reliable primary(master) <> render node
mapping. Although this may work in some cases, it is not correct.
Add a couple of helpers that hide the details and provide the name of
the master or render device name, given an fd. The latter may belong to
either the master, control or render node device.
v2:
- Rename Device and Primary to Master (aka the /dev/dri/cardX device).
- Check for the file via readdir_r() rather than stat().
- Wrap the check into a single function.
- Return NULL for non-linux platforms.
v3:
- Don't segfault if name is NULL.
- Update function names, as suggested by Frank Binns.
v4:
- Update commit message to reflect the function name changes.

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.

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.

Hi Alex,
Enclosed is a revised version of the patch sent on Mar 18, against
the master branch of the drm userspace (i.e. libdrm). Details
summarised in this thread:
http://lists.freedesktop.org/archives/dri-devel/2011-March/009499.html
This patch reconciles libdrm with the the kernel change that Dave
pushed this morning. It *supersedes* the previously sent patch (i.e.
apply it to the master branch as it exists at the time of this writing,
not as an incremental patch to the one sent previously).
Regards,
Ilija
