The arrays specified by ctx->Array._DrawArrays are used for all
vertex drawing via vbo_context::draw_prims(). Different arrays are
used for immediate mode, vertex arrays, display lists, etc. Changing
from one to another requires updating derived/driver array state.
Before, we indirectly specifid the arrays with the gl_draw_method values.
Now we just directly specify the arrays instead. This is simpler and
will allow a subsequent display list optimization.
In the future, it might make sense to get rid of ctx->Array._DrawArrays
entirely and just pass the arrays as another parameter to
vbo_context::draw_prims().

After the context is initialized, the API and context flags won't
change. So, we can compute whether vertex attribute 0 aliases
vertex position just once.
This should make the glVertexAttrib*() functions a little quicker.

It's now basically a single expression, so it probably makes sense to
have it inlined into the callers.

The term "client array" is a legacy thing dating back to the pre-VBO
era when _all_ vertex arrays lived in client memory.
Nowadays, it only contains vertex array state which is derived from
gl_array_attributes and gl_vertex_buffer_binding. It's used by the
VBO module and some drivers.

_mesa_enable_vertex_array_attrib
Pulls the parts of enable_vertex_array_attrib that aren't just parameter
validation out into a function that can be called from other parts of
Mesa (e.g., meta).
_mesa_enable_vertex_array_attrib can also be used to enable
fixed-function arrays.

Fredrik's implementation of ARB_vertex_attrib_binding introduced new
gl_vertex_attrib_array and gl_vertex_buffer_binding structures, and
converted Mesa's older gl_client_array to be derived state. Ultimately,
we'd like to drop gl_client_array and use those structures directly.
One hitch is that gl_client_array::_MaxElement doesn't correspond to
either structure (unlike every other field), so we'd have to figure out
where to store it. The _MaxElement computation uses values from both
structures, so it doesn't really belong in either place. We could put
it in the VAO, but we'd have to pass it around everywhere.
It turns out that it's only used when ctx->Const.CheckArrayBounds is
set, which is only set by the (rarely used) classic swrast driver.
It appears that drivers/x11 used to set it as well, which was intended
to avoid segmentation faults on out-of-bounds memory access in the X
server (probably for indirect GLX clients). However, ajax deleted that
code in 2010 (commit 1ccef926be46dce3b6b5c76e812e2fae4e205ce7).
The bounds checking apparently doesn't actually work, either. Non-VBO
attributes arbitrarily set _MaxElement to 2 * 1000 * 1000 * 1000.
vbo_save_draw and vbo_exec_draw remark /* ??? */ when setting it, and
the i965 code contains a comment noting that _MaxElement is often bogus.
Given that the code is complex, rarely used, and dubiously functional,
it doesn't seem worth maintaining going forward. This patch drops it.
This will probably mean the classic swrast driver may begin crashing on
out of bounds vertex buffer access in some cases, but I believe that is
allowed by OpenGL (and probably happened for non-VBO accesses anyway).
There do not appear to be any Piglit regressions, either.

The derived state approach currently used (_RestartIndex) doesn't work:
in the GL_PRIMITIVE_RESTART_FIXED_INDEX case, the restart index depends
on the index buffer's data type, and that isn't known until draw time.
The existing code also fails to obey the GL 4.3 rules which say that
FIXED_INDEX takes precedence over normal primitive restart.
This helper function correctly determines the restart index, and will
replace the derived state.
NOTE: This is a candidate for the 9.1 branch.
