* Brings us closer to core profile, all matrices are working, and apart
from a problem with text drawing, Blender is working fine.
* Reduce the coding overhead of having to setup/teardown when
alternating between 2D and 3D drawing sessions.
* Gives us fewer modes and states we need to keep track of.
Unfortunatelly this also "rejects a fundamental change" the original
design was trying to make - that 2D is different from 3D and
deserves its own best implementation.
That said, it is still aligned with the function API design as
originally implemented (i.e., it still uses gpuTranslate2D, ...).
Finally, if you build with core profile and this patch you get:

[The text glitch is an unrelated issue].

On Apple we use OpenGL 2.1 + an ARB extension for framebuffers.
The glFramebufferTexture function is part of OpenGL 3.0 but not part of the ARB extension. This commit fills that gap.
All other platforms are using GL 3.0+ already so it's not an issue there. All platforms (Mac too) will use GL 3.3+ soon so this workaround will be removed.
These were the last few glGetUniformLocation calls in source/blender.
The new system gets uniform information once when a shader is created, then uses this cached info every time after that.
This removes glGetBooleanv queries for GL_LIGHTING. This has been #ifdef'd
out with legacy opengl disabled. Thus a false positive still shows up in
the gl queries. Also, note that this removes support for wireframes in
opensubdiv, when desabling legacy opengl, which should be fixed later.

Some elbeem debug functions had old gl drawing calls. I removed the
functions instead of converting, because Blender doesn't even build
with them enabled anymore, because some elbeem debug libs got removed
at some point.

This supports our common character animation workflow, where a character,
its rig, and the custom bone shapes are all part of a group. This group
is then linked into the scene, the rig is proxified and animated. Such
a group can now be exported. Use "Renderable objects only" to prevent
writing the custom bone shapes to the Alembic file.
The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

... even though 3x3 feels better.
This is a compromise to get core profile up & running sooner. Eventually I'd like to finish the original 3x3 plans, but this commit will let us get on with other tasks.
External API stays (almost) the same. Our GLSL shaders can use this without any changes.

These functions mark the beginning and end of 3D drawing, causing the matrix API to use our own implementation instead of legacy OpenGL.
Part of T49450
Look up "name[0]" when asked for "name", since that marks the beginning of the array.
We're comparing to the name stored in ShaderInterface which comes from glGetActiveUniform.
This eliminates tons of glGetUniformLocation calls from the drawing loop. Vast majority of code can keep making the same function calls. They're just faster now!

- immUniform*
- gpuBindMatrices
