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.

Change-Id: I8ca64cd1acd6cabf915bf54689ec2e5f6dfa495a
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.

better fix for [3028370] GL get error should return a valid error if no context is bound.
it turns out that we cannot return INVALID_OPERATION from glGetError() because the
GL spec says that it must be called in a loop until it returns GL_NO_ERROR.
now, we always return 0 from GL functions called from a thread with no
context bound. This means that glGetError() will return NO_ERROR in this case,
which is better than returning a random value (which could trap the app in a loop).
if this happens in the main thread of a process, we LOG an error message once.

improve a bit the implementation of eglGetProcAddress
rework how our EGL wrapper manages EGLConfig:
- we now store the EGLConfig with the EGLSurface and EGLContext
so that we can have easy access to it from eglQueryContext
and eglQuerySurface.
- EGLConfig now are an index into a sorted table of egl_config_t,
we use a binary search to retrieve our EGLConfig (the index) from
the implementation's EGLConfig.
- egl_config_t keeps track of the implementation's index,
EGLConfig and CONFIG_ID as well as our CONFIG_ID.
In many ways, this implementation is simpler and more robust, as it doesn't
assume anything about the number of implementations nor what EGLConfig is
made of (the previous code assumed EGLConfig didn't usem more than 24-bits).

Previously we imlpemented the standard semantics for
eglInitialize / eglTerminate, which are that
eglInitialize may be called any number of times,
but the first call to eglTerminate will terminate
the display.
Now we follow reference-countins semantics, which
means that eglTerminate will only terminate the
display when the reference count returns to zero.
This change allows EGL to be used by multiple
independently written modules in the same process.
(Otherwise there is no way for the independent
modules to coordinate their use of the display.)
Duplicate ARCH_ARM_HAVE_TLS_REGISTER BoardConfig to proprocessor
HAVE_ARM_TLS_REGISTER define from Bionic's libc Android.mk to ensure that

Adds support for formerly-unimplemented methods:
glCurrentPaletteMatrixOES
glLoadPaletteFromModelViewMatrixOES
glMatrixIndexPointerOES
glWeightPointerOES
The bulk of the changes are related to implementing the two PointerOES
methods, which are implemented pretty much the same way as the existing
Pointer methods were implemented.
This change also changes the way glPointSizePointerOES is implemented,
making it act like all the other Pointer methods. (Previously it was
not handling non-direct-buffer arguments correctly.)
Fixes bug 2308625 "Support matrix palette skinning
in JSR239 and related APIs"
Also updated GLLogWraper to fix two bugs in GLLogWrapper that were
discovered while testing matrix palette skinning support:
a) Handle trying to print the contents of null-but-enabled buffers.
(It's not legal to draw with null-but-enabled buffers, and
in fact some OpenGL drivers will crash if you try to render in this
state, but there's no reason the GLLogWrapper should crash while trying
to debug this situation.
b) Don't read off the end of a vertex buffer with non-zero position when
printing the entire contents of the vertex buffer. Now we only print from
the current position to the end of the buffer.
add a way to convert a mapped "pushbuffer" buffer to a gralloc handle
which then can be safely used by surfaceflinger, without including
gralloc_priv.h
Instead of using a different function pointer table for ES 1.x and ES 2.x,
we use a single one that is the union (sort|uniq) of both tables. Two
instances of this table are initialized with pointers to GL ES 1.x and GL ES 2.x
entry-points.
When a context is created, we store its version number and when it is bound to a
thread we set the approruiate table based on the stored version.
This introduce no penalty while dispatching gl calls to the right API version.
[Pending Dr No approval for MR1]
this change fixes the lifetime mgt of EGLSurface, EGLContext and EGLImageKHR in the EGL wrapper.
EGLDisplay is still somewhat bogus and libagl's EGL is still incorrect.
The idea of the change is that EGL objects are put in a list when created and removed when destroyed.
Before each use, we first verify if the object is in the list and if so a reference is taken and kept
for the scope of the whole EGL API being called, if not, an error is returned.
Upon object destruction, the object is simply marked as "terminated" (this is not protected by a lock
because it doesn't really matter). This flag is only used to deny access to the object by other APIs
while it's still valid (for instance current or being used by another function in another thread).
A reference is also removed and the object can then actually be destroyed when going out of scope.
refactored the code so that:
- EGL APIs that can be called before or after eglInitialize() will work by loading the drivers first
- make eglGetDisplay() a lot more efficient
- make sure that EGL drivers are loaded in a thread-safe way
- don't unload the drivers upon calling eglTerminate(), they're now never unloaded, since there is no safe way to do it (some thread could be running)
- updated our EGL version to 1.4
- return better error codes if errors happen during initialization

ANDROID_swap_rectangle allows to specify the rectangle affected by eglSwapBuffers(), anything outside of this rectangle is unchanged. in particular EGL_BUFFER_DESTROYED only applies to that rectangle. This extension as well as EGL_BUFFER_PRESERVED allow major optimizations on surfaceflinger, which can redraw only the dirty area during compositing.
However, ANDROID_swap_rectangle allows further optimizations in EGL by reducing the amount of copy-back needed. ANDROID_swap_rectangle is particularily important for software implementations.
