To enable multi-touch on a tethered device, allow a callback to be
registered with the OpenGL renderer. On every frame, the framebuffer
is read into system memory and provided to the callback, so it can be
mirrored to the device.
This change is co-dependent on Idae3b026d52ed8dd666cbcdc3f3af80175c90ad3
in external/qemu.

All ten libraries can now be built in 64-bit named "lib64*" (*)
in addition to the original 32-bit form named "lib*".
Also, dlopen "lib64*so" in 64-bit.
(*) eg. In Ubuntu, all can be built with the following command:
make out/host/linux-x86/lib/lib64OpenglRender.so \
out/host/linux-x86/lib/lib64EGL_translator.so \
out/host/linux-x86/lib/lib64GLES_CM_translator.so \
out/host/linux-x86/lib/lib64GLES_V2_translator.so
Rules to build static libraries lib64log.a, lib64cutils.a and lib64utils.a
they depend were added in other CLs.

1. "emugen" generates four *dec.cpp files containing code like this
to decode offset to pointer in stream
tmp = *(T *)(ptr + 8 + 4 + 4 + 4 + *(size_t *)(ptr +8 + 4 + 4));
If *dec.cpp are compiled in 64-bit, size_t is 8-byte and dereferencing of
it is likley to get wild offset for dereferencing of *(T *) to crash the
code. Solution is to define tsize_t for "target size_t" instead
of using host size_t.
2. Cast pointer to "uintptr_t" instead of "unsigned int" for 2nd param of
ShareGroup::getGlobalName(NamedObjectType, ObjectLocalName/*64bit*/).
3. Instance of EGLSurface, EGLContext and EGLImageKHR are used as 32-bit
key for std::map< unsigned int, * > SurfacesHndlMap, ContextsHndlMap,
and ImagesHndlMap, respectively. Cast pointer to uintptr_t and assert
upper 32-bit is zero before passing to map::find().
4. Instance of GLeglImageOES is used to eglAttachEGLImage() which expect
"unsigned int". Cast it to uintptr_t and assert upper 32-bit is zero.
5. The 5th param to GLEScontext::setPointer is GLvoid* but contains 32-bit
offset to vbo if bufferName exists. Cast it to uintptr_t and assert
upper 32-bit is zero.
6. Use %zu instead of %d to print size_t
7. Cast pointer to (uintptr_t) in many other places

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 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
in your environment or your BoardConfig.mk (see tools/emulator/opengl/Android.mk)
