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.

* EGLImageTargetRenderbufferStorageOES was incorrectly accepting
TEXTURE_EXTERNAL_OES as a target. Revert that; the host GL will
correctly reject it with INVALID_ENUM.
* Handle the REQUIRED_TEXTURE_IMAGE_UNITS_OES texparameter query.
* Validate texture parameters set on TEXTURE_EXTERNAL textures;
otherwise invalid parameters would work on the emulator but not on a
real device.

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

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.
Change-Id: I580cda82ba0fb44f12b75aa0bbacf5cd9f15f744
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.

Also changed emugen to generates gl_ftable.h needed for
getProcAddress implementation.
Added not_api attrib to emugen's gl.attrib to exclude from the
generated ftable.
Change-Id: I03786ea5d5a640bbcf5efccadca5bf2ec3e09fca
This is the first commit for the GLESv1 implementation.
It also includes needed fixes in emugen to support const types.
Also, changed glFinish definition in gl.in to match the
definition as in gl.h.
