st/vbo: clone vbo module and rename structs to st_vbo

Want to acheive a couple of things here:
1) Build a better immediate vertex handler
2) Build gallium vertex buffer/element state directly from st_vbo module
3) Avoid breaking all the DRI drivers in the process

The vbo code is pretty fragile and even small changes there seem to
break DRI drivers left & right.  In part that's due to the lack of a
strong interface between the shared code and the drivers, and also to
the fairly ill-defined interface between core mesa and the VBO module.

Hopefully this branch will help figure out a better interface between
mesa and the vertex code, and will be able to do so without breaking
other drivers in the process.

If this branch turns out well, it may be interesting to back-port some
of the changes here to the original VBO module.

+ * \mainpage The ST_VBO builder module
+ *
+ * This module hooks into the GL dispatch table and catches all vertex
+ * building and drawing commands, such as glVertex3f, glBegin and
+ * glDrawArrays.  The module stores all incoming vertex data as arrays
+ * in GL vertex buffer objects (ST_VBOs), and translates all drawing
+ * commands into calls to a driver supplied DrawPrimitives() callback.
+ *
+ * The module captures both immediate mode and display list drawing,
+ * and manages the allocation, reference counting and deallocation of
+ * vertex buffer objects itself.
+ * 
+ * The DrawPrimitives() callback can be either implemented by the
+ * driver itself or hooked to the tnl module's _tnl_draw_primitives()
+ * function for hardware without tnl capablilties or during fallbacks.

+    *
+    * In the case of hardware tnl, we want to avoid starting the
+    * upload at zero, as it will mean every draw call uploads an
+    * increasing amount of not-used vertex data.  Worse - in the
+    * software tnl module, all those vertices might be transformed and
+    * lit but never rendered.
+    *
+    * If we just upload or transform the vertices in start..end,
+    * however, the indices will be incorrect.
+    *
+    * At this level, we don't know exactly what the requirements of
+    * the backend are going to be, though it will likely boil down to
+    * either:
+    *
+    * 1) Do nothing, everything is in a ST_VBO and is processed once
+    *       only.
+    *
+    * 2) Adjust the indices and vertex arrays so that start becomes
+    *    zero.
+    *
+    * Rather than doing anything here, I'll provide a helper function
+    * for the latter case elsewhere.

+/* Display list compiler attempts to store lists of vertices with the
+ * same vertex layout.  Additionally it attempts to minimize the need
+ * for execute-time fixup of these vertex lists, allowing them to be
+ * cached on hardware.
+ *
+ * There are still some circumstances where this can be thwarted, for
+ * example by building a list that consists of one very long primitive
+ * (eg Begin(Triangles), 1000 vertices, End), and calling that list
+ * from inside a different begin/end object (Begin(Lines), CallList,
+ * End).  
+ *
+ * In that case the code will have to replay the list as individual
+ * commands through the Exec dispatch table, or fix up the copied
+ * vertices at execute-time.
+ *
+ * The other case where fixup is required is when a vertex attribute
+ * is introduced in the middle of a primitive.  Eg:
+ *  Begin(Lines)
+ *  TexCoord1f()           Vertex2f()
+ *  TexCoord1f() Color3f() Vertex2f()
+ *  End()
+ *
+ *  If the current value of Color isn't known at compile-time, this
+ *  primitive will require fixup.
+ *
+ *
+ * The list compiler currently doesn't attempt to compile lists
+ * containing EvalCoord or EvalPoint commands.  On encountering one of
+ * these, compilation falls back to opcodes.  
+ *
+ * This could be improved to fallback only when a mix of EvalCoord and
+ * Vertex commands are issued within a single primitive.
