fix glGetAttachedShaders
NULL is allowed in count parameter
fix problem with nvidia driver which returned invalid count

needed changes to support glEGLImageTargetRenderbufferStorageOES,
added implementation in egl and added tokens to renderControl.
Also fixed function pointers returned by eglGetProcAddress to
return functions that works independant of the current context,
see system/egl/ClientAPIExts.cpp
That makes the egl_image conformance test to pass on the guest.

some applications and conformance tests expects to have
non-zero bit counts for all red,green and blue channels.
The translator expose all EGL compliant configs, including
monochrome and RG configs.
We now filter those out and expose to the guest only the RGB
configs.

Uniform locations are 32-bit values which the application queries
from the driver after a shader program is linked. It seems that Cordy
game (possibly all Unity based apps) store the returned location as
16-bit value. Intel driver returns location values in the upper 16-bit
range :(
This is a workaround for this issue, when a program is linked we check
the locations of all uniforms, if all locations are within the upper
16-bit range (as with Intel driver) we shift the location value before
returning to the application. Also override all functions which take
a location parameter and do the reverse shift before sending a location
value to the host.

The GLES and OpenGL specs for glFramebufferTexture2D are different, which
caused valid GLES calls to fail when moved over to OpenGL. Specifically,
a framebuffer in OpenGL must have a color attachment in order to be valid
for draw, while in GLES it doesn't. So add a validate function, and call
it from each drawing API call.
This patch also contains a workaround for a bug in the ATI driver, where
changing the framebuffer attachments requires a rebind of the framebuffer.

to overcome a bug in intel driver which returnes incorrect precision
and range for integers. query the driver for precision format only
for floats. for integers, we return values defined in gles spec.
Change-Id: Idfec2826d811220873c18f301cf4268fc54dabee
fix the default values of vertex attrib array to match gles spec
size should be initialized to 4, and type should be initialized to GL_FLOAT

genName in the globalNameSpace now calls the glGen* function of opengl
to generate a global name instead of inventing one.
this is to overcome a bug in intel driver which raises glError when
binding a framebuffer/renderbuffer with a name that was not generated
by opengl.

resize the internal pbuffer we use for a WindowSurface
when a color buffer of different size is attached to the "window".
That fixes "Glyder 2 by glu" application view while loading.
