eglGetProcAddress should return a function pointer that does not
depends on the current bounded context (if any), when the user
calls one of the function pointers returned from eglGetProcAddress
for one of the GLES extension functions, the GLESv1 or GLESv2
version of the extension function shold be called depending on
the current bounded context.
For this we have added a ClientAPI (GLES) extension dispatch
table in the EGL level which points to static functions in libEGL
where each function checks in runtime the current bound context and
calls down to the GLES_CM -or- GLESv2 library function.
See ClientAPIExts.cpp, when new GLES extension functions are added
to GLESv1 or GLESv2 its definition should be added to
ClientAPIExts.in as well.
This fixes the segfault in egl_image conformance test.

Handle EGL context and surfaces destrouction using ref counting
pointer (SmartPtr) rather then maintaining a "markForDeletion" flag.
This has required to re-arrange the ThreadInfo structure to be local
to EGL rather then in the GLcommon area so that we will be able to
place a ref-counted pointer to the current context in the TLS.
That fixes the crash during exit of covgl conformance test.

The was a bug in the calculation of the pixels data size, caused by wrong usage
of pack/unpack alignment.
Pack should be used for glReadPixels, while unpack should be used for glTexImage and such.
Also fixes crash in "Angry Birds" & "Angry Birds Rio"

This is needed to support the rare, but still legal scenario,
when glDrawElemets is used with some index array data is stored in VBO's
while the actual attributes (vertices) data is in immediate mode.
When in immediate mode, we need to process the incodes, in order to know
which vertex data to send, which was impossible without the caching.
This commit introduces a new class GLSharedGroup, which will hold all data
that can be shared by shared contexts (buffers are such data).
This also makes the "Jet Cars Stunts" app work properly.

In case we're receiving packets larger then the initial size
of the read buffer, we dynamicaly grow (X2 steps) the size of
the buffer. An example for this large buffer is a 4MB texture
in JetCarStunts.

On every swapBuffers, we make sure to decRef on the prev buffer,
and incRef on the current buffer. This fixes all the anoying
crashes on application exit, and also after the speech windows
on Replica Island

This change modifies the function declarations under
developement/tools/emulator/opengl/host/include/render_api.h
to make them callable from C.
This is preparation work for integrating the rendering library
into the emulator. The plan is to dlopen() the library dynamically
and using non-mangled function names makes using dlsym() both
easier and more portable.

Adds GLSL built in constants defined in GLSL ES but not in GLSL.
Makes biConstant conformance test to pass on Mac (where ES2_compatability is not
present).
Also fixed the GLSL parser to insert our additions to the shader
only after the "#version" token if exist in the original shader.
Also renamed env var GOOGLE_GLES_FORCE_GLSL_VERSION to
GOOGLE_GLES_DEFAULT_GLSL_VERSION to better match its functionality since
we use it only if no specific version exist in the shader code.

Both the ATI and nVidia OpenGL drivers return the wrong answer on
glGetIntegerv(GL_ALPHA_TEST_REF). So Implement this functionality
in our code.
Change-Id: I022b1475f7edb9f1d0f48ebcaf9f6e9f5c4f344e
enable workarounds by default
added environemnt variable GOOGLE_GLSL_FORCE_GLES_VERSION
to the shader parser

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

Turns out that updating crtbegin_so.o and crend_so.o is not
enough for the standalone toolchain. We also need to update
the object files used to generate static and dynamic
executables.
This fixes the standalone toolchain NDK tests.
