Contrary what the name may suggest, LLVM's opaque types are used for
recursive types -- types whose definition refers itself -- so opaque
types correspond to pre-declaring a structure in C. E.g.:

struct link {

struct node *next;
};
struct node {
struct link link;
}
Void pointers are also disallowed by LLVM. So the suggested way of creating

softpipe: check for null pointers during context create/destroy
See http://bugs.freedesktop.org/show_bug.cgi?id=32309
Apparently, malloc() is failing during context creation. Not
checking for nulls here led to crashes elsewhere.

graw: fix logic error in pixel format selection
The loop to choose a pixel format for the window was incrementing
'i' after we succeeded in creating the window so if we chose format[0]
for graw_create_window_and_screen() we were putting format[1] in
the pipe_resource template for creating the render target.
This only worked because of the order of the elements in the formats[]
array.
The graw_xlib.c code now properly compares the requested gallium pixel
format against the visual's color layout.
Update all the graw demos to fix the off-by-one-i error.
