r600: use gallium list macros instead of making our own.
before this change, r600 glxinfo segfaulted in the list code, and I wasn't
debugging another linked list implementation, its 2010 after all.
So add the two missing list macros to the gallium header from X.org list header file (after fixing them), then port all r600 lists to the new header.
