* 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.

The emulator EGL implementation tried to hold its own reference to
buffers acquired/released with dequeueBuffer/queueBuffer, but was
missing an incRef after dequeueBuffer during swapBuffers.
Since the native window holds a reference to the buffer between
dequeueBuffer and queueBuffer, the EGL reference isn't needed anyway.

The glBufferData, glBufferSubData, and glDeleteBuffers entry points
had interception routines in GL2Encoder which cache the data, but they
weren't hooked up. So when glDrawElements tried to retrieve the cached
data it wasn't there.

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

When remapping a GLES texture to a different GL texture in
glEGLImageTargetTexture2DOES(), the GLES texture's previous GL texture was
deleted unconditionally. This is bad when it came from an EGLImage and is
therefore owned by (and will continue to be used by) some other object.
The code now skips deleting the old GL texture if it came from an EGLImage.
This mirrors the logic in glDeleteTextures().

The EGL->GL translator implementation of glEGLImageTargetTexture2DOES was
properly replacing uses of the target texture object with the texture object
associated with the EGLImage in the host GL library, but wasn't updating its
own info about the texture (dimensions, etc.). This broke places where the
translator relied on knowing this, e.g. when implementing the GLES glDrawTexi
call on top of GL glDrawArrays.

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 adds a rather extensive document explaining the design
of our OpenGLES emulation, both on the guest and the host.

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

This patch adds support for Win32 named pipes for the communication
channel between the Opengl renderer library and its clients.
Named pipes should be much faster than local TCP sockets on this
platform. Note that by default, TCP sockets are still used. The
emulator needs to call setStreamMode(STREAM_MODE_PIPE) to be able
to use these.
Change-Id: I86d36624cf2b7fdd50f41e1e43c908348dca4657
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 re-enables the build of the gralloc GLES emulation library.
This is only for experimentation / debugging purpose. GLES emulation
is still disabled by default in the emulator. Even if you force-enable
it by using the '-gpu on' flag, this module will not properly yet
and nothing will be displayed.

This fixes the definition of the emulator-specific egl.cfg file
used to indicate to our EGL system library which support modules
are available in the emulator.
We need to list two modules here:
'emulation' corresponding to GPU emulation
'android' corresponding to the software renderer
The indices before each name correspond to the 'display' and 'impl'
numbers that are expected by frameworks/base/opengl/libs/EGL/Loader.cpp
In a nutshell, 'display' should always be 0, and 'impl' should be 0
for the software renderer, and 1 for a hardware-based one. See the code
under framewors/base/opengl/libs/EGL/egl.cpp for mode details.

The gralloc.goldfish module cannot build in master because
the gralloc interface evolved considerably since gingerbread
(which the current code is based on).
For now, disable it completely, this will make it impossible
to test GPU emulation in the internal master tree for now.
We'll have to port this module to the new world-order to solve
this.

This adds an initLibrary() function to libOpenglRender.
It will be used by the emulator to fallback on software rendering
if the library cannot be initialized properly, e.g. if it is not
possible to load the host EGL/GLES libraries.
