Replace GSQueue with BLI_Stack for image filling

Was doing a malloc per pixel, and a redundant memcmp,
BLI_Stack chunks memory more efficiently.

BGE debug API and actuator

This patch adds some new debug methods to the KX_GameObject for manually adding the debug list and bge.render for controlling the debug visualization.
It also adds a new debug actuator, which allows to control the same functions.

This patch is a updated version of T33701.

Correct error in BM_face_split_edgenet when no faces are split

Fix potential bug in loop normals code.

Even if we cannot use computed lnor, we still have to empty the fan stack of lnors!

Another attempt for T40981, clipping border does not work with GLSL on
ATIs.

This is actually a test to see if this can be enabled on ATI cards.
According to various sources, newer ATI cards supporting GLSL 3.0
support gl_ClippingDistance in shaders, which is the forward compatible
way to do custom clipping.

This fix will bind 6 additional varying variables on ATIs, which may
lead to some shaders not compiling due to limiting out of those
variables, or to performance degradation. Also I do not have an ATI
handy to test.

Having those in mind, this commit may well be reverted later.

Clipping planes are usually 4 (6 is for cube clipping), but making
shaders depend on viewport state is really bad, and would lead to
recompilation, so I took the worst case here to avoid that.
Hopefully driver does some optimization there.
