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.

opengles emulator: fix the uniform location WAR for intel platforms
Fixed the location shift WAR to work for arrays that starts at
location 0. Fixed conformance regressions made by this workaround.
The conversion should be smarter than just shifting 16-bits back
and forth, it should take into account if array element is being
accessed.

opengles emulator: fix uniform name translation to apps
add special handling of locations smaller or equal to 0
do not translate location -1 (this location means the
uniform is not found)
location 0 does not need translation, it has no effect

opengles emulator: Workaround Cordy (Unity) bug with intel driver.
Uniform locations are 32-bit values which the application queries
from the driver after a shader program is linked. It seems that Cordy
game (possibly all Unity based apps) store the returned location as
16-bit value. Intel driver returns location values in the upper 16-bit
range :(
This is a workaround for this issue, when a program is linked we check
the locations of all uniforms, if all locations are within the upper
16-bit range (as with Intel driver) we shift the location value before
returning to the application. Also override all functions which take
a location parameter and do the reverse shift before sending a location
value to the host.

opengles emulator: fix glGetUnifrom
added state tracking for uniforms in program objects
for each active uniform in index i we will save its starting location
,size and type, so when calling glGetUniform on its location,
we can tell how many bytes we should read from the stream according to
the uniform's type
add some type and size definitions to functions
that calculate size from enum
some other fixes to the codec

opengles emulator: cache all buffer 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.
