Because of the way the SDK and Android system images are branched,
host code that goes into the SDK tools can't live in the same
repository as code that goes into the system image. This change keeps
the emugl host code in sdk.git/emulator/opengl while moving the emugl
system code to development.git/tools/emulator/opengl.
A few changes were made beyond simply cloning the directories:
(a) Makefiles were modified to only build the relevant components. Not
doing so would break the build due to having multiple rule
definitions.
(b) Protocol spec files were moved from the guest encoder directories
to the host decoder directories. The decoder must support older
versions of the protocol, but not newer versions, so it makes
sense to keep the latest version of the protocol spec with the
decoder.
(c) Along with that, the encoder is now built from checked in
generated encoder source rather than directly from the protocol
spec. The generated code must be updated manually. This makes it
possible to freeze the system encoder version without freezing the
host decoder version, and also makes it very obvious when a
protocol changes is happening that will require special
backwards-compatibility support in the decoder/renderer.
(d) Host-only and system-only code were removed from the repository
where they aren't used.
(e) README and DESIGN documents were updated to reflect this split.
No actual source code was changed due to the above.

The emulator GLES support has two interfaces: a host shared library
interface used by QEMU, and a protocol between the platform and the
host. The host library interface is not versioned; QEMU and the GLES
renderer must match. The protocol on the other hand must be backwards
compatible: a new GLES renderer must support an older platform image.
Thus for branching purposes it makes more sense to put the GLES
renderer in sdk.git, which is branched along with qemu.git for SDK
releases. Platform images will be built against the protocol version
in the platform branch of sdk.git.

* commit '76780669f9867587693563358ccdc903e9cdcbba':
Added rules to build 64-bit libraries for 64-bit emulator

All ten libraries can now be built in 64-bit named "lib64*" (*)
in addition to the original 32-bit form named "lib*".
Also, dlopen "lib64*so" in 64-bit.
(*) eg. In Ubuntu, all can be built with the following command:
make out/host/linux-x86/lib/lib64OpenglRender.so \
out/host/linux-x86/lib/lib64EGL_translator.so \
out/host/linux-x86/lib/lib64GLES_CM_translator.so \
out/host/linux-x86/lib/lib64GLES_V2_translator.so
Rules to build static libraries lib64log.a, lib64cutils.a and lib64utils.a
they depend were added in other CLs.

1. "emugen" generates four *dec.cpp files containing code like this
to decode offset to pointer in stream
tmp = *(T *)(ptr + 8 + 4 + 4 + 4 + *(size_t *)(ptr +8 + 4 + 4));
If *dec.cpp are compiled in 64-bit, size_t is 8-byte and dereferencing of
it is likley to get wild offset for dereferencing of *(T *) to crash the
code. Solution is to define tsize_t for "target size_t" instead
of using host size_t.
2. Cast pointer to "uintptr_t" instead of "unsigned int" for 2nd param of
ShareGroup::getGlobalName(NamedObjectType, ObjectLocalName/*64bit*/).
3. Instance of EGLSurface, EGLContext and EGLImageKHR are used as 32-bit
key for std::map< unsigned int, * > SurfacesHndlMap, ContextsHndlMap,
and ImagesHndlMap, respectively. Cast pointer to uintptr_t and assert
upper 32-bit is zero before passing to map::find().
4. Instance of GLeglImageOES is used to eglAttachEGLImage() which expect
"unsigned int". Cast it to uintptr_t and assert upper 32-bit is zero.
5. The 5th param to GLEScontext::setPointer is GLvoid* but contains 32-bit
offset to vbo if bufferName exists. Cast it to uintptr_t and assert
upper 32-bit is zero.
6. Use %zu instead of %d to print size_t
7. Cast pointer to (uintptr_t) in many other places

Off-by-two bug when removing textures from the tracking array could
overwrite malloc's mem chunk data structure, usually resulting in a
heap corruption abort on a later malloc/realloc/free.

* Disable verbose debug spam.
* Add missing GL enum to utility function. The default case was
returning the correct size, so this doesn't fix any bugs, just
removes some logcat spam.
* Comment and whitespace corrections.

EmuGL: implement OES_EGL_image_external for GLESv1
|

| |

GLESv2 support will come in a followup change but will take advantage
of the GLClientState changes.

This patches fixes a minor invalid usage of delete (instead of delete[])
and reformats the source code a little to make it more obvious.

This patch allows an auto-generated GLES encoder function to write
'isLarge' buffers with a custom writer, instead of calling stream->readFully()
directly.
This is intended to allow writing pixel or vertex data that is stored
with a specific stride.
Another patch will introduce the corresponding changes to the .attrib files

This patch modifies the guest encoding libraries to avoid
un-necessary copies when sending large buffers (e.g. pixels)
to the host. Instead, the data is sent directly through a
new IOStream method (writeFully()).
On my machine, this improves the NenaMark2 benchmark
(from 50.8 to 57.1 fps). More importantly, this speeds up
the display of non-GL surfaces too, which are sent through
the special rcUpdateColorBuffer() function in gralloc_goldfish.
This is noticeable in many parts of the UI (e.g. when scrolling
through lists).
To tag a given parameter, use the new 'isLarge' variable flag
in the protocol .attrib file.
Implemented for the following encoding functions:
rcUpdateColorBuffer
glTexSubImage2D
glTexImage2Di
glBufferData
glBufferSubData
glCompressedTexImage2D
glCompressedTexSubImage2D
glTexImage3DOES
glTexSubImage3DOES
glCompressedTexImage3DOES
glCompressedTexSubImage3DOES
+ Optimize the auto-generated encoder functions to avoid
repeated function calls (for size computations).

The modules here are only built when BUILD_EMULATOR_OPENGL is defined to true
in your environment or your BoardConfig.mk (see tools/emulator/opengl/Android.mk)
