This fixes three issues:
1. glGet(GL_2d_TEXTURE_BINDING) should be handled by the translator rather
than by OpenGL.
2. glIsTexture shoud return GL_TRUE only if the texture was bound at some
point - add a wasBound member to the TextureData and maintain it.
3. glTexParameter(GL_GENERATE_MIPMAP) did not work. The first problem was
that it was not allowed by our validator - fixed. The next issue is that
this enum is not necessarily supported by the OpenGL implementation - it
is in OpenGL 2.x, but was replaced by an extension in 3.x. So in case the
extension does not exist, and GL_GENERATE_MIPMAP is required, save this info
in a new requiresAutoMipmap member of TextureData and call glGenerateMipmapExt
whenever glTex(Sub)Image2D is called.
There is a theoretical case where neither GL_GENERATE_MIPMAP nor glGenerateMipmap
is supported by the OpenGL implementation - this is not likely to happen, but
if we find such an implementation it might require implementing a mipmap
generation software algorithm (which is bad).
There is a set of glGets which query the client state of the
binded arrays. The data exists in the translator context and is not
passed to GL, so the glGets should be handled internaly.
This is done by implementing four glGet*v methods in GLEScontext, which
return a boolean value indicating whether we have set the return value
or not, and are called by the glGet*v functions in GLEScmImp.
Two of the glGets are handled by GLEScontext, and the other 15 by
GLEScmContext since they are specific to GLES 1.1. The same should be
done for 2.0 specific glGets in a later patch.
Also. bufferName is now saved in GLESPointer in to allow the
GL_*_ARRAY_BUFFER_BINDING get.
Our implementation of eglGetProcAddress() resolves the function addresses
in run time. Typically this is not an issue, but when a gl function is
also implemented by the calling app the address was resolved to the calling
app's version of the function rather than ours. This is the case with the
glDrawTex{isfx}OES functions in the 1.1 conformance test.
The solution is to add the -Bsymbolic switch when linking our libraries,
so all symbol resolution is done internaly.
The same fix should probably be done for Mac.
inserting some of the logic which was scattered over some parts
of the GLESContext class to be encpsulated inside the ConversionArrays
so that the code will be more clea and organized.
fix shader and program names in glDeleteShader/Program
fix object name manager to accept objects with name 0
fix unbinding of buffers,framebuffers and renderbuffers
separate getPointer to have specific implementation for gles 1 and 2
fix number of supported texture images to match GL
fix incorrect optimization that skips draw on false conditions
set its glFormat to GL_RGB since GL_RGB565_OES is not supported on the host.
This also fixes the wallpaper issue, making it visible.

fixed functions calling conventions in dispatch tables,
added link flag to translator libraries to produce an alias
function for all exported functions with stdcall name mangling.

The GL2Encoder::m_compressedTextureFormats member wasn't initialized, so the d'tor
would sometimes crash trying to delete it. Also init m_num_compressedTextureFormats.

Added GLESv2 library to system.
Made fixes to the host libOpenGLRender to
compile and support GLESv2 (defined WITH_GLES2).
Other fixes required to make GLESv2 to work.

Added a return value for rcFlushWindowColorBuffer and
rcUpdateColorBuffer in order to make those calls to block
with a round-trip to the host. This is to make sure that
the color buffer is up-to-date before the flinger use it
for rendering.
Also added a call to the native windows's lock function after
EGL is attached and bound to render on the window. This call
was missed before.
This syncronization can be optimized by removing the round-trip
and insert sync primitive to the stream at every draw command that
reads from a color buffer to make the sync happen on the host
before rendering the color buffer and remove the need for the
guest to wait for that update.

The config_size argument in rcChooseConfig should match the number
of requested configs and not the size in bytes to store it.
Moved the configs array size computation into rendeerControl.attrib.

This fix performs a flip software copy to match our coords with those expected by the flinger.
We may think of a better implementation in the future.

This patch is a major rework of the build opengl-emulation
build scripts. See README for details.
In a nutshell, this introduces various functions that considerably
simplify the declaration of the 26+ modules in this implementation,
by handling auto-generation of sources and module imports/exports.

Fixed bug in list implementation in gralloc_free which caused a crash,
also removed some log prints.

Added rcGetGLString token to renderControl to query
a GL string constant from the current context from the host.
Implement glGetString functinality in EGL so that the string
value can be cached in the context structure and also
implementation can be shared between GLESv1 and GLESv2.
Also, fixed clientAPI context initialization check in
eglMakeCurrent. The check was for the previously bounded
context instead for the newly bounded context.

Initialize EGL extensions functions in the EGLDispatch
table using eglGetProcAddress instead of dlsym.
(try dlsym if eglGetProcAddress failed).
Change-Id: I256c4c5f9f3728a5b0e4d5bbcc75b83aa8a85f29
Fixed eglGetProcAddress when called for egl
extension functions.
Also fixed a typo in the EGL extension string.

The created texture format which represents the color buffer must
be of type GL_RGB or GL_RGBA also for the 565/5551 surface formats.

When re-binding the same context the resoult was that the
surfaces got unbinded from the context.
Fixed that situation and added an optimization to do nothing
in case of re-binding the same context to the same binded surfaces.
