Move emugl system code to development.git
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.

Move emulator GLES from development.git to sdk.git
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.

emulator: opengl: 'large' buffer optimization
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).

emulator: opengl: Back-port GLES emulation from the master tree.
The modules here are only built when BUILD_EMULATOR_OPENGL is defined to true

opengles emulator: fixed renderer termination flow
Handling clean exit of the renderer when stopOpenGLRenderer
is called. This is done by openning a connection to the renderer
and flag that it should exit. Added 'clientFlags' field which must
be send after every connection is made to the renderer for this purpose.
The server will wait for running rendering threads to exit and then will
close all EGL/GL resources and will exit. The stopOpenGLRenderer will
return only when the renderer has exited.

Moved IOStream.h to be used in external API for libOpenGLRender.
This change includes four changes:
1) moved IOStream.h into host/include/libOpenGLRender, this directory
will include the api interface into the libOpenGLRender which will be
used later by the emulator and we need this interface to use IOStream.h
2) Updated Andorid.mk files to include the new directory location of IOStream.h
in the LOCAL_C_INCLUDE.
3) Added new function "read" to IOStream which reads a message without a givven
size.
4) Updated TcpStream to use "cutils/sockets.h" instead of using directly the socket api for portability reasons. (It now compiles on windows as well).
