We have to use _mesa_inside_dlist_begin_end instead of
_mesa_inside_begin_end to see if we are inside a glBegin/glEnd block in
case of display lists.
So split the is_vertex_position function used in vertex attribute processing
into a imm and dlist variant and use the appropriate _mesa_inside_begin_end
variant.

Factor out struct gl_vertex_format from array attributes.
The data type is supposed to describe the type of a vertex
element. At this current stage the data type is only used
with the VAO, but actually is useful in various other places.
Due to the bitfields being used, special care needs to be
taken for the glGet code paths.
v2: Change unsigned char -> GLubyte.
Use struct assignment for struct gl_vertex_format.

Instead of keeping a copy of the vertex array content in
struct gl_vertex_array only keep pointers to the first order
information originaly in the VAO.
For that represent the current values by struct gl_array_attributes
and struct gl_vertex_buffer_binding.
v2: Change comments.
Remove gl... prefix from variables except in the i965 directory where
it was like that before. Reindent because of that.

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().

This patch splits the context's CurrentDispatch pointer into two
pointers, CurrentClientDispatch, and CurrentServerDispatch, so that
when doing multithread marshalling, we can distinguish between the
dispatch table that's being used by the client (to serialize GL calls
into the marshal buffer) and the dispatch table that's being used by
the server (to execute the GL calls).

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.

If the attribute type is changing, we would have found that earlier in
the ATTR_UNION() macro and would have called vbo_exec_fixup_vertex().
So move the assignment into that function so we don't do it every time.

In bc4e0c4 (vbo: Use a bitmask to track the active arrays in vbo_exec*.)
we stopped looping over all the attributes and resetting all slots.
Which exposed an issue in vbo_exec_bind_arrays() for handling GENERIC0
vs. POS.
Split out a helper which can reset a particular slot, so that
vbo_exec_bind_arrays() can re-use it to reset POS.
This fixes an issue with 0ad (and possibly others).

Very long line loops which spanned 3 or more vertex buffers were not
handled correctly and could result in stray lines.
The piglit lineloop test draws 10000 vertices by default, and is not
long enough to trigger this. Even 'lineloop -count 100000' doesn't
trigger the bug.
For future reference, the issue can be reproduced by changing Mesa's
VBO_VERT_BUFFER_SIZE to 4096 and changing the piglit lineloop test to
use glVertex2f(), draw 3 loops instead of 1, and specifying -count
1023.

When long GL_LINE_LOOP primitives don't fit in one vertex buffer they
have to be split across buffers. The code to do this was basically correct
but drivers had to pay special attention to the _mesa_prim::begin,end flags
in order to draw the sections of the line loop properly. Apparently, the
only drivers to do this were those using the old 'tnl' module for software
vertex processing.
Now we convert the split pieces of GL_LINE_LOOP prims into GL_LINE_STRIP
primitives so that drivers don't have to worry about the special begin/end
flags. The only time a driver will get a GL_LINE_LOOP prim is when the
whole thing fits in one vertex buffer.
Mostly fixes bug 81174, but not completely. There's another bug somewhere
in the src/gallium/auxiliary/draw/ code. If the piglit lineloop test is
run with -count 4096, rendering is correct, but with -count 4097 there are
stray lines. 4096 is a magic number in the draw code (search for "4096").
Also note that this does not fix long line loops in display lists. The
next patch fixes that.
v2: fix incorrect -1 in vbo_compute_max_verts(), per Charmaine. Remove
incorrect assertion which was added in vbo_copy_vertices().
