This patch modifies GLDispatch.cpp in the translator libraries
to open the Darwin GL library as a framework. Using a hard-coded
system path prevents the requirement to modify LD_LIBRARY_PATH
or DYLD_LIBRARY_PATH to point to the directory that contains the
library.
In this specific case, this is equivalent to
/System/Frameworks/OpenGL.framework/Libraries/libGL.dylib
But is the "kosher" way to open it the library.

You can still re-enable them by uncommenting one line in
development/tools/emulator/opengl/Android.mk

These libraries are only used by libOpenglRender, so make them
static so that their code is included in this shared library
instead. This reduces the shared library dependencies that
will be required from the emulator.

This patch forces the default definition of BUILD_EMULATOR_OPENGL_DRIVER
to true by default, which is the common case where we will build the
goldfish-specific gralloc hardware module to allow SurfaceFlinger to
use GLES emulation exclusively.
The only reason to define thi to 'false' today is to debug specific
apps, but this requires displaying the GL output in a different window
than the emulator to be usable.

It is possible to move the final installation path of a shared
library by using LOCAL_MODULE_PATH/LOCAL_UNSTRIPPED_PATH in its
module declaration.
We do this for example to put certain libraries under /system/lib/egl
or /system/lib/hw.
However, the Android build system has a small bug where you cannot
depend on these shared libraries because it will complain it doesn't
find them under /system/lib, the default install location.
More precisely, consider libfoo defined as:
include $(CLEAR_VARS)
LOCAL_MODULE := libfoo
LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)/egl
...
include $(BUILD_SHARED_LIBRARY)
Its final binary will be installed to /system/lib/egl/libfoo.so
Now, let's write a module that depends on it, as:
include $(CLEAR_VARS)
LOCAL_MODULE := libbar
LOCAL_SHARED_LIBRARIES += libfoo
...
include $(BUILD_SHARED_LIBRARY)
The build system will complain there is no rule to define the target
/system/lib/libfoo.so, but the target should be /system/lib/egl/libfoo.so.
A work-around is to define libbar as follows instead:
include $(CLEAR_VARS)
LOCAL_MODULE := libbar
LOCAL_ADDITIONAL_DEPENDENCIES := $(TARGET_OUT_SHARED_LIBRARIES)/egl/libfoo.so
...
include $(BUILD_SHARED_LIBRARY)
This works if you don't need to link against the library when building your
shared library (which is fortunately the case for the GLES emulation
libraries).
That's essentially what this patch implements under common.mk. We update
emugl-set-shared-library-subpath to record that a module has been "moved",
and we avoid adding them to the LOCAL_SHARED_LIBRARIES variable of the
modules that export it.
+ Simplify three Android.mk files accordingly.

Do not redefine SDL_CONFIG to avoid conflicts with the emulator's
build system which depend on its definition. Note that this has
been fixed in another patch (https://review.source.android.com/25684)
but it is also cleaner to do this here.

add drawValidate when calling glCheckFramebufferStatus
in the draw validate, a color attachement will be added to the
framebuffer if there is no target attached to COLOR_ATTACHMENT
of the framebuffer.
opengl does not allow framebuffer with no color attachement
so CheckFramebufferStatus would return INCOMPLETE status.
We already call drawValidate before any draw, the call was
missing at glCheckFramebufferStatus.

There is a flashing effect we see on Mac when switching between
drawables (pbuffer and a window) on the same context.
This change make the FrameBuffer object in the renderer to use
two different OpenGL contexts, one which is used while the pbuffer
drawable is bound and another which is used when the subwindow is
bounded during swap. The two contexts share textures so both contexts
have access to all allocated color buffers.
While this fixes the flashing effect on Mac, it should be more effective on
other platforms as well.

Wrong share group was set up when two user contexts are sharing !
That means that shared context was not really worked before, now it does.

This make the EGL/GLESv1/GLESv2 libraries on the guest to use
the OPENGL bionic tls slot for faster tls access.
Note that we still setting the slower tls in order to have the
tls destructor which allow us to close the host connection
when the thread exits.
Gives slightly performance improvement, the avg score for the
teapot test in 0xBench goes from 34 to 37 fps. (This test is
near immediate mode since it renders a lot of small primitives
so it is a good candicate to be improved).

This change removes the 'blitFromPbuffer' path in the renderer
which uses binding pbuffer to texture. This path does not work
on all platforms and is not relavent any more. It simplifies
a lot the FBConfig filtering code.
Also, added a check to fail the renderer initialization if
the translator plugin does not support EGL_KHR_gl_texture_2d_image
and GL_OES_EGL_IMAGE (by both GLES implementations [1 and 2])
since our implementation requires it.

That replaces the readback to host we do at the end of each frame
with two blits on the GPU, one to copy the pixels into a texture
and another to render the texture to another in order to flip
the image.
