This allows a more generic mechanism for passing user configurations
into drivers by accessing the dri options directly.

This follows the model of imx (display) and etnaviv (render): pl111 is a
display-only device, so when asked to do GL for it, we see if we have a
vc4 renderer, make the vc4 screen, and have vc4 call back to pl111 to do
scanout allocations.
The difference from etnaviv is that we share the same BO between vc4 and
pl111, rather than having a vc4 bo and a pl11 bo and copies between the
two. The only mismatch between their requirements is that vc4 requires
4-pixel (at 32bpp) stride alignment, while pl111 requires that stride
match width. The kernel will reject any modesets to an incorrect stride,
so the 3D driver doesn't need to worry about that.

val_bool and val_int are in a union. val_bool gets the first byte, which
happens to work on LE when setting via the int, but breaks on BE. By
setting the value properly, we are able to use DRI3 on BE architectures.
Tested by running glxgears with a NV34 in a G5 PPC.

Reminiscent from the pre-loader days, were we had multiple instances of
the loader logic in separate places and one could build a "GALLIUM_ONLY"
version.
Since that is no longer the case and the loaders (glx/egl/gbm) do not
(and should not) require to know any classic/gallium specific we can
drop the argument and the related code.

Render nodes have been around for quite some time. Removing support via

compilation and simplify the build greatly.
For example currently we the pipe-loader, which explicitly links against
xcb and friends (for X auth) if found at compile-time. That
would cause problems as one will be forced to use X/xcb, even if it's a
headless system that is used for opencl.

The goal is to have a uniform interface to create winsys and
pipe_screen instances for any driver, exposing the device enumeration
capabilities that might be supported by the operating system (for now
there's a "drm" back-end using udev and a "sw" back-end that always
returns the same built-in devices).
The typical use case of this library will be:
>
> struct pipe_loader_device devs[n];
> struct pipe_screen *screen;
>
> pipe_loader_probe(&devs, n);
>[pick some device from the array...]
>
> screen = pipe_loader_create_screen(dev, library_search_path);
>[do something with screen...]
>
> screen->destroy(screen);
> pipe_loader_release(&devs, N);
>
A part of the code was taken from targets/gbm/pipe_loader.c, which
will be removed and replaced with calls into this library by a future
commit.
