This is not really a bug, but the nVidia shader compiler is much more
liberal than the GLSL spec, and allows compilation of shaders which
do not comply with the spec. This is an issue for passing the
conformance tests, but more importantly it will allow bad shader written
by the app developer to pass on the emulator and then to fail on the device.
Adding "#version 100" definition to the head of a shader source disables
this liberal behavior. For now this is activated in run time by the "NV_WAR"
environment variable.

When calling RenderbufferStorage with internalformat=GL_RGB565
we will create one with internal format GL_RGB
the same for glTexImage2D
Change-Id: I1e464dd36142f586beef6bf895456c7aab1b8237
support different binding to GL_TEXTURE_2D and GL_TEXTURE_CUBE_MAP
targets
create 2 default texture object, to be bound when BindTexture( ... ,0)
is called.
in order to do this, we must ensure their names are internal only, so the user can't
use these names by accident.
the object name manager local name is now 64 bit to allow generation of internal names

Do not allow glLinkProgram to succeed if only one shader type has been
attached to the program, GL allows this, but GLES2 does not.
added state tracking for program objects to check which shaders are
attached to the program object.
add a way to define object data type being held for each object in objectNameManager
ProgramData and ShaderParser are both valid objectData for objects in SHADER namespace
we need a way to determine object type to generate correct errors

This fixes the Windows build of the opengl emulation code.
The official is not broken because you still need to define
BUILD_EMULATOR_OPENGL=true in your environment to enable the
code to be built.

Instead of calling the dispatcher directly. This will make sure all Translator's
internals (such as TextureData data) are updated properly.
This also fixes the bug in "Replica Island" - when the green robot was invisible,
because it's TextureData wasn't updated by doCompressedTexImage2D
The pointer to glTexImage2D is passed as a parameter to doCompressedTexImage2D,
otherwise Windows resolve the glTexImage2D symbol in the external libGL rather
than the translator's code. Longer term, we will remove the translator's link
to libGL, at which point this parameter will be removed.
The getGlobalName function returns 0 on error. There are many places
were no error checking is done after calling it to get a shader or
program name. Typically this shouldn't be an issue, since the follwing
OpenGL call using a value of 0 will generated the required GL_INVALID_VALUE,
but this does not always happen.

This fixes a crash caused by covgl (on Nvidia linux driver) when our implementation
of glDrawTexOES calls glDrawArrays with GL_TEXTURE_COORD_ARRAY enabled - but none of texture
units are enabled and no data passed by glTexCoordPointer

The ARB_ES2_compatibility extension supports several GLES 2.0 enums
and functions on OpenGL 2.0. Seems it exists on nVidia drivers, but
not on ATI's. So implement its functionality in case it doesn't
exist on the host.

in Windows platform we previously defined EGLNativeDisplaytype to be WinDisplay*
( this was defined in include/EGL/eglplatform.h) this was OK as long as we used the
the EGL_DEFAULT_DISPLAY as parameter for eglGetDisplay meaning we were generating
a native display by oureselv and wrapping it, but there was aproblem when we got the
EGLNativeDisplayType from the user (as HDC in Windows) but interpret it as WinDisplay*
this caused a big memory corupption.
so to overcome this problem we now define two types EGLNativeDisplayType to be
HDC and EGLNativeInternalDisplayTypeto be WinDisplay*, and when we get in eglGetDisplay
a parameter different from EGL_DEFAULT_DISPLAY we wrap it with the struct of WinDisplay
and return it to the user.
this change caused a change in all the declerations of EglOsApi.h changing
EGLNativeDisplayType -> EGLNativeInternalDisplayType

This commit does few things:
1. Gets doCompressedTexImage2D out of the context and TextureUtils
2. Gets palette textures out of TextureUtils and into PaletteTexture
3. Makes TextureUtils generic for all compressed textures
4. Moves the glGet's dealing with compressed textures from GLEScontext to the impl.
