Eric added some new code to check if offset < obj_size before computing
_MaxElement but my original code was still present afterward and it
clobbered the _MaxElement value.
Not sure if this came from a bad merge or what.
The _TriangleCaps bit is deprecated, not updated when we require, and
is set based on state that hasn't been updated at that point in
_mesa_update_state_locked().
Fixes incorrect clear color in glsl/twoside.c with meta_clear_tris.
Otherwise, a pointer greater than the size would underflow and give a large
maximum element.

Used to be done in the glVertex/Normal/Color/etc/Pointer() calls but
if the VBO was reallocated the size could change.
New _NEW_BUFFER_OBJECT state flag.
This state flag will be used to indicate that vertex/fragment program
constants have changed. _NEW_PROGRAM will be used to indicate changes
to the vertex/fragment shader itself, or misc related state.
_NEW_PROGRAM_CONSTANTS is also set whenever a program parameter that's
tracking GL state has changed. For example, if the projection matrix is
in the parameter list, calling glFrustum() will cause _NEW_PROGRAM_CONSTANTS
to be set. This will let to remove the need for dynamic state atoms in
some drivers.
For now, we still set _NEW_PROGRAM in all the places we used to. We'll no
longer set _NEW_PROGRAM in glUniform() after drivers/etc have been updated.
This fixes a regression in fbotest1 on 915, where a transition from
color+vertex array enabled to texcoord0+vertex array enabled wouldn't trigger
program update on the second _mesa_update_state of DrawArrays, and we'd sample
a constant texcoord of 0,0,0,1 instead of the array.
The double state update in DrawArrays from
1680ef8696 still needs fixing.
When a hw driver fell back to swrast, swrast wasn't always getting informed
of program changes. When fixed function is translated into shaders, flags
like _NEW_LIGHT, _NEW_TEXTURE, etc. should really signal _NEW_PROGRAM.
In this case, swrast wasn't seeing _NEW_PROGRAM when new fragment shaders
were generated.
This is the big merge of the gallium-0.2 branch into master.
gallium-master-merge was just the staging area for it.
Both gallium-0.2 and gallium-master-merge are considered closed now.

This fixes a regression introduced in 46ae1abbac
Break program validation into two steps, do part before texture state
validation and do the rest after:
1. Determine Vertex/Fragment _Enabled state.
2. Update texture state.
3. Determine pointers to current Vertex/Fragment programs (which may involve
generating new "fixed-function" programs).
See comments in the code for more details of the dependencies.
Program state needs to be updated before texture state since the later depends
on the former.
Fixes piglit texgen failure. The second time through the modes (press 't'
three times) we disable the fragment program and return to conventional texture
mode. State validation failed here because update_texture() saw stale fragment
program state.
There was a note in state.c about _Active deserving to die, and there were
potential issues with it due to i965 forgetting to set _UseTexEnvProgram.
Removing both simplifies things.

Patch provide by Keith.
Used in state tracker by DrawPixels to indicate that the state tracker (driver)
is using its own vertex program. This prevents the texenvprogram code from
replacing conventional shader inputs with state vars.
Fixes glDraw/CopyPixels regressions.
Keep track of enabled/active vertex attributes.
Keep track of potential vertex program outputs.
When generating fragment program, replace references to fragment attributes
which are effectively non-varying and non-computed passthrough attributes with
references to the new CURRENT_ATTRIB tracked state value.
Only downside is slight ugliness in VBO code where we need to validate state
twice in succession.
Also, check the FEATURE flags in many places.
