gallium: new raw gallium interface to support standalone tests

Provides basic window system integration behind a simple interface,
allowing tests to be written without dependency on either the driver
or window system.

With a lot of work, could turn into something like glut for gallium.

+# rasterizers into a single driver.  A software rasterizer is defined
+# as any driver which takes an sw_winsys pointer as the only argument
+# to create_screen.
+#
+# XXX: unfortunately users of this driver still need to link in any
+# extra libraries needed for the particular driver (eg llvm for
+# llvmpipe).  Not sure how to get around this.
