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.

This patch allows the OpenGLES rendering library to use Unix
sockets instead of TCP ones when communicating with its clients.
On certain benchmarks (e.g. 0xBench teapot), this provides a
noticeable improvement (x1.05 fps) without any other changes.
On practice, Unix sockets are faster than TCP sockets, even
local ones. Also, this introduces a moderate amount of
abstraction that will allow us to use Win32 named pipes
on Windows (where TCP sockets are much slower than they
are on Unix).
Note that by default, TCP streams are still used.
The client (emulator) must call the new API 'setStreamMode'
to change it to STREAM_MODE_UNIX between 'initLibrary' and
'startOpenglRenderer' calls.
+ Adjust callers / user appropriately.

This patch improves the performance of the TcpStream implementation
on the host by disabling the Nagle algorithm, thus improving the
bandwidth of small packets.
When used with the corresponding change in the emulator, this
significantly improves the speed of OpenGLES emulation for many
applications.

Make the event pump loop in the renderer process we do on Windows
exit when the Framebuffer's subwindow is destroyed.
Fixed TcpStream to close the socket using 'closesocket' on windows,
otherwise the other end of the socket does not sense that the socket
is closed.
+ Use WS_DISABLED to ensure that our GL subwindow doesn't receive
any input events.

This patch modifies the guest libraries to use the new
fast qemu "opengles" pipe to communicate with the host
renderer process.
Note that the renderer is still listening on a TCP socket
on port 22468.

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).

Move system/OpenglCodecCommon into shared/OpenglCodecCommon so it's code
can be shared among more components of the project.
Move tests/ut_renderer/TimeUtils.* into a the common area
Annotate ErrLog.h and GLDecoderContextData.h with the project license statement
