This happens when glGetMultisamplefv (or any other non-draw function) is
called, which doesn't invoke the VBO module to update _DrawArrays and
the pointer is invalid at that point.
However st/mesa still dereferences it to setup vertex buffers ==> crash.

The main GL context's swtnl_im field is the VBO module's vbo_context
structure. Using the name "swtnl" in the name is confusing since
some drivers use hardware texturing and lighting, but still rely on the
VBO module for drawing.
v2: Forward declare the type and use that instead of void *
(suggested by Eric Anholt).
v3: Remove unnecessary cast (pointed out by by Topi Pohjolainen).

The previous commit introduced extra words, breaking the formatting.
This text transformation was done automatically via the following shell
command:
$ git grep 'THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY' | sed 's/:.*$//' | xargs -I {} sh -c 'vim -e -s {} < vimscript
where 'vimscript' is a file containing:
/THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY/;/\*\// !fmt -w 78 -p ' * '

This brings the license text in line with the MIT License as published
on the Open Source Initiative website:
http://opensource.org/licenses/mit-license.php
Generated automatically be the following shell command:
$ git grep 'THE AUTHORS BE LIABLE' | sed 's/:.*$//g' | xargs -I '{}' \
sed -i 's/THE AUTHORS/THE AUTHORS OR COPYRIGHT HOLDERS/' {}
This introduces some wrapping issues, to be fixed in the next commit.

The intention here is to protect all authors, not just Brian Paul. I
believe that was already the sensible interpretation, but spelling it
out is probably better.
More practically, it also prevents people from accidentally copy &
pasting the license into a new file which says Brian is not liable when
he isn't even one of the authors.

The functions were broken, because they converted ints to floats.
Now we can finally advertise OpenGL 3.0. ;)
In this commit, the vbo module also tracks the type for each attrib
in addition to the size. It can be one of FLOAT, INT, UNSIGNED_INT.
The little ugliness is the vertex attribs are declared as floats even though
there may be integer values. The code just copies integer values into them
without any conversion.
This implementation passes the glVertexAttribI piglit test which I am going
to commit in piglit soon. The test covers vertex arrays, immediate mode and
display lists.
NOTE: This is a candidate for the stable branches.

The vbo module recomputes its states if _NEW_ARRAY is set, so it shouldn't use
the same flag to notify the driver. Since we've run out of bits in NewState
and NewState is for core Mesa anyway, we need to find another way.
This patch is the first to start decoupling the state flags meant only
for core Mesa and those only for drivers.
The idea is to have two flag sets:
- gl_context::NewState - used by core Mesa only
- gl_context::NewDriverState - used by drivers only (the flags are defined
by the driver and opaque to core Mesa)
It makes perfect sense to use NewState|=_NEW_ARRAY to notify the vbo module
that the user changed vertex arrays, and the vbo module in turn sets
a driver-specific flag to notify the driver that it should update its vertex
array bindings.
The driver decides which bits of NewDriverState should be set and stores them
in gl_context::DriverFlags. Then, Core Mesa can do this:
ctx->NewDriverState |= ctx->DriverFlags.NewArray;
This patch implements this behavior and adapts st/mesa.
DriverFlags.NewArray is set to ST_NEW_VERTEX_ARRAYS.
Core Mesa only sets NewDriverState. It's the driver's responsibility to read
it whenever it wants and reset it to 0.

In the future we'd like to treat vertex arrays as a state and
not as a parameter to the draw function. This is the first step
towards that goal. Part of the goal is to avoid array re-validation
for every draw call.
This commit adds:
const struct gl_client_array **gl_context::Array::_DrawArrays.
The pointer is changed in:
* vbo_draw_method
* vbo_rebase_prims - unused by gallium
* vbo_split_prims - unused by gallium
* st_RasterPos

It's not nice when you have several variables pointing to the same array
and you wanna ask your editor "where is this used" and you only get an answer
for one of the four currval, legacy_currval, generic_currval, mat_currval,
which is quite useless, because you never see the whole picture.
Let's get rid of the additional pointers.

vbo/vbo_save* are the last members on the omit list. Test FEATURE_dlist
in the sources and remove the omit list.

If we're running a vertex program to emulated fixed-function, we still need
to treat vertex arrays/attributes as if we're in fixed-function mode.
This should probably be back-ported to Mesa 7.5 after a bit more testing.

NV_vertex_program implementation has slightly incorrect aliasing
behaviour. I think this is reasonable given the simplification and
the fact that the mainstream ARB_vp continues to have the correct
behaviour.

rather than VBO's - VBOs are easy but need to look closer at the
driver interface. The trivial/tri demo works.
