add drawValidate when calling glCheckFramebufferStatus
in the draw validate, a color attachement will be added to the
framebuffer if there is no target attached to COLOR_ATTACHMENT
of the framebuffer.
opengl does not allow framebuffer with no color attachement
so CheckFramebufferStatus would return INCOMPLETE status.
We already call drawValidate before any draw, the call was
missing at glCheckFramebufferStatus.

We re-organized the code to live in one of the existing packages and
therefore we no longer need the tests to be run on their own.

Added basic stylus and hover support to the sample to illustrate
the usage of pressure, size, orientation, distance, tilt and tool type
information.

There is a flashing effect we see on Mac when switching between
drawables (pbuffer and a window) on the same context.
This change make the FrameBuffer object in the renderer to use
two different OpenGL contexts, one which is used while the pbuffer
drawable is bound and another which is used when the subwindow is
bounded during swap. The two contexts share textures so both contexts
have access to all allocated color buffers.
While this fixes the flashing effect on Mac, it should be more effective on
other platforms as well.

Wrong share group was set up when two user contexts are sharing !
That means that shared context was not really worked before, now it does.

This make the EGL/GLESv1/GLESv2 libraries on the guest to use
the OPENGL bionic tls slot for faster tls access.
Note that we still setting the slower tls in order to have the
tls destructor which allow us to close the host connection
when the thread exits.
Gives slightly performance improvement, the avg score for the
teapot test in 0xBench goes from 34 to 37 fps. (This test is
near immediate mode since it renders a lot of small primitives
so it is a good candicate to be improved).

This change removes the 'blitFromPbuffer' path in the renderer
which uses binding pbuffer to texture. This path does not work
on all platforms and is not relavent any more. It simplifies
a lot the FBConfig filtering code.
Also, added a check to fail the renderer initialization if
the translator plugin does not support EGL_KHR_gl_texture_2d_image
and GL_OES_EGL_IMAGE (by both GLES implementations [1 and 2])
since our implementation requires it.

That replaces the readback to host we do at the end of each frame
with two blits on the GPU, one to copy the pixels into a texture
and another to render the texture to another in order to flip
the image.

This patch improves the performance of the TcpStream implementation
on the host by disabling the Nagle algorithm, thus improving the
bandwidth of small packets.
When used with the corresponding change in the emulator, this
significantly improves the speed of OpenGLES emulation for many
applications.
