This patch adds two improvements:
1. Protobuf messages are buffered and sent in chunks.
2. Multiple EGL contexts are handled properly: Corresponding
to each EGLContext, a GLTraceContext with a unique ID is created.
On eglMakeCurrent, the appropriate GLTraceContext is set and is
used while tracing subsequent GL Calls in that thread.

Currently, gltrace always attaches the contents of the currently
bound framebuffer. This patch changes it to attach the contents
of FB0 on eglSwap, and the currently bound framebuffer for the
glDraw* calls.

Currently, the contents of the FrameBuffer are sent by encoding
them as the last argument to the function call. As a result, it is
not possible to know if a message has the framebuffer encoded in it
without looking at the function type.
This patch modifies the protobuf definition to include a separate
optional framebuffer message.

This patch provides a framework for tracing GLES 1.0 and 2.0
functions. It is missing a lot of features, but here are the
things it accomplishes:
- Stop building the glesv2dbg library, and build the
glestrace library instead.
- Replace the hooks for glesv2dbg with the ones for glestrace.
- Add the basics for the trace library. Currently, this
traces all GL functions, but not all required data is
sent for all the functions. As a result, it will not
be possible to reconstruct the entire GL state on the
host side.
The files gltrace.pb.* and gltrace_api.* are both generated
using the tools/genapi.py script.

This change explicitly sets swap interval 1 on the window when an
EGLSurface is created to render to it.

This change introduces two new BoardConfig variables to control the size
limits of the EGL blob cache. MAX_EGL_CACHE_ENTRY_SIZE is the size
limit for values inserted into the cache, and MAX_EGL_CACHE_SIZE is the
size limit for all entries in the entire cache (including both keys and
values). If either of these BoardConfig variables are not defined then
a default size limit is used instead.

- don't advertise extensions that are not supported
by any implementation
- remove EGL_ANDROID_swap_rectangle which is not
implemented by anybody and confuses people
- add some comments about mandatory extensions

the code that validated EGL objects dereferenced the object
to access its EGLDisplay -- needed for validation (!).
This was wrong for two reasons, first we dereferenced the object
before validating it (potentially leading to a crash), secondly
we didn't validate that the object existed in the right EGLDisplay.
We now use the EGLDisplay passed by the user API.

This change adds the ANDROID suffix to the all the types and functions
defined by the EGL_ANDROID_blob_cache extension.

This does not happen on high end gfx devices. This happens
only if only one EGL context is initialized in the current
process.

This change causes any insertions into the EGL cache to trigger an
attempt to save the cache contents to disk. The save operation is
deferred to allow multiple cache insertions to be batched up.

This change adds support for saving and loading the contents of the EGL
cache. It also adds some simple tests for the EGL cache.

This patch modifies the library loaded in libEGL.so to
handle the case of GLES emulation as follows:
- if we detect that we run inside the emulator, check the
GPU emulation status through ro.kernel.qemu.gles, which
will be set to 1 if supported, or 0 otherwise.
When trying to run on an older version of the emulator,
the kernel parameter will not be defined at all.
- if GPU emulation is supported, use egl.cfg as usual.
It will contain a line like "0 0 emulation" that will
load libEGL_android.so appropriately.
- nothing is changed if we don't run inside the emulator.
NOTE: Ideally, we would modify libEGL_emulation.so to
redirect all calls to libEGL_android.so in this case.
However, this turns out to be extremely tedious to implement
(too many functions with different signatures).
As such, it is much simpler to make the check before
loading the library.

This change moves the call to native_window_api_disconnect from
eglDestroySurface to the egl_surface_t destructor. The egl_surface_t
can outlive the external EGLSurface if eglDestroySurface is called while
the surface is made current on a thread.

the original connect/disconnect hooks are deprecated
and replace by api_connect/api_disconnect. the original
hooks are no no-ops.
api_connect/api_disconnect is now only called from the
android framework.

This change adds an enum value and a description of the expected
implementations to the EGL_ANDROID_recordable extension specification.
It also adds the new enum value to the 'eglext.h' header.

This change fixes how the Android EGL layer overrides the size and
format of an ANativeWindow in eglCreateWindowSurface. The new behavior
is to leave the size untouched when overriding the format. The previous
behavior was to reset the ANativeWindow to use the default size set by
the ANativeWindow implementation.
It also adds two new 'perform' methods to the ANativeWindow interface:
set_buffers_dimensions and set_buffers_format, and redefines the
behavior of set_buffers_geometry to be the combination of these two new
methods.
Additionally, this change adds an error check for the return value of
the new native_window_set_buffers_format call, which required adding a
(stub) handler for to FramebufferNativeWindow.
