This fixes the definition of the emulator-specific egl.cfg file
used to indicate to our EGL system library which support modules
are available in the emulator.
We need to list two modules here:
'emulation' corresponding to GPU emulation
'android' corresponding to the software renderer
The indices before each name correspond to the 'display' and 'impl'
numbers that are expected by frameworks/base/opengl/libs/EGL/Loader.cpp
In a nutshell, 'display' should always be 0, and 'impl' should be 0
for the software renderer, and 1 for a hardware-based one. See the code
under framewors/base/opengl/libs/EGL/egl.cpp for mode details.

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.

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).

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.

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.

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

Support for eglChooseConfig with configs==NULL.
Also added small change to query EGL_LARGEST_PBUFFER attrib of surfaces.
Fixed error print in QemuPipeStream::readFully.
Those changes make sure that covegl completes & passes on the emulator with Translator
on linux in the backend.

Added GLESv2 library to system.
Made fixes to the host libOpenGLRender to
compile and support GLESv2 (defined WITH_GLES2).
Other fixes required to make GLESv2 to work.
Change-Id: I9eb198e6092e7fa3550342c50929dd1714282cb3
Added a return value for rcFlushWindowColorBuffer and
rcUpdateColorBuffer in order to make those calls to block
with a round-trip to the host. This is to make sure that
the color buffer is up-to-date before the flinger use it
for rendering.
Also added a call to the native windows's lock function after
EGL is attached and bound to render on the window. This call
was missed before.
This syncronization can be optimized by removing the round-trip
and insert sync primitive to the stream at every draw command that
reads from a color buffer to make the sync happen on the host
before rendering the color buffer and remove the need for the
guest to wait for that update.

The config_size argument in rcChooseConfig should match the number
of requested configs and not the size in bytes to store it.
Moved the configs array size computation into rendeerControl.attrib.

Added rcGetGLString token to renderControl to query
a GL string constant from the current context from the host.
Implement glGetString functinality in EGL so that the string
value can be cached in the context structure and also
implementation can be shared between GLESv1 and GLESv2.
Also, fixed clientAPI context initialization check in
eglMakeCurrent. The check was for the previously bounded
context instead for the newly bounded context.

We need to share the cb_hande_t between gralloc/EGL/GLES, moved it
into the opengl system common lib.
Also added eglSwapBuffers implementation.
