Small fix for Glew

This is easy config for Android
First you have to have Android toolcahain
See instructions inside

It turns off most of the flags because they aren't supported.
Essentually, it will move inside main CMake and work as any other OS

This is essentually enables Android build using cmake on linux
Mac might be used too, but you need to modify CmakeList
Full instructions will be posted later
It still kinda complicated because it involves a lot of manual steps
WITH_ANDROID - to enable
Libs comming up

We have seperate glew for Android and OpenGL ES
It eliminates X11 dependency and provides stub for functions
Still, it must be more flexible

OpenGL Policy - Assume vertex arrays are disabled, enabled the ones needed, disable all when done.

BGE was assuming that it was the only module using vertex arrays.

Hive main patch
===============
Give the possibility to pass the game control to a python script, the game engine ends when the python script returns. This patch is necessary for the hive system because it needs to control the main loop.

To active this feature, add a custom property "__main__" to the startup scene and set it to the name of a text block that contains the python script.
"NextFrame" python function is provided in the GameLogic module to execute one frame of the BGE, i.e. logic bricks, physics and render. The function returns FALSE if the game hit an exit condition, TRUE otherwise.
Example:

# this python will reproduce the behavior of the BGE (with poor timing):
import GameLogic, time
while GameLogic.NextFrame():
time.sleep(0.016)

Notes: * This feature is used internally by the hive system.
* This interface is unstable, it may change in the future
* It is not yet possible to load a new game or restart the game from python

removed unused typedef

misc. fixes and optimizations of gpuImmediate

* Need to know the lock count of gpuImmediate, not just if its locked
* Use ClientActiveTexture before TexCoordPointer, not ActiveTexture
* Only set blending state one when drawing text
* Do not use gpuBegin right away because the texture hasn't been loaded yet
* The maximum number of texture units calculation depends on the GL version

Missed CMakeLists.txt in last commit

Added GPU_STRING_MARKER calls to text_draw.c

Added GPU_utility.h

Contains GPU_STRING_MARKER macro for using the glStringMarkerGREMEDY function that lets send messages to an OpenGL debugger.

gcc fixes 2

difference between (void) and ()

pointer type difference (GLenum* <-> GLint*)

too many arguments for gpuEnd()

fixes for gcc

difference between (void) and ()

gave GPU_IMMEDIATE an initializer so it was not considered "common"

conflicting qualifiers on certain functions

fixed include file capitalization issue

fixed some asserts that fire in debug mode

been building in release all day for profiling and forgot to check

Cannot use restrict with a function pointer.

Merged r46824-r46992

missing header file

Improved the pathological behavior of the text editor.

Now batches up multiple characters to draw at once. My changes could use some refactoring, but I'd like to put it on the back shelf. All I needed to do for now is keep it from being unusable.
