The was a bug in the calculation of the pixels data size, caused by wrong usage
of pack/unpack alignment.
Pack should be used for glReadPixels, while unpack should be used for glTexImage and such.
Also fixes crash in "Angry Birds" & "Angry Birds Rio"

This is needed to support the rare, but still legal scenario,
when glDrawElemets is used with some index array data is stored in VBO's
while the actual attributes (vertices) data is in immediate mode.
When in immediate mode, we need to process the incodes, in order to know
which vertex data to send, which was impossible without the caching.
This commit introduces a new class GLSharedGroup, which will hold all data
that can be shared by shared contexts (buffers are such data).
This also makes the "Jet Cars Stunts" app work properly.

Thought the spec doesn't speak about null in data parameter,
it is checked in covgl - so we'll base it on glTexImage2D and allow
null in data.

Sometimes we need to check parameter values before encoding
to prevent crashes, for example:
glDeleteBufferes(-1, ptr); - would crash
For that we need to check some gl errors on the guest.
The change adds error state to the encoder and also
adds new feature to emugen which allows to insert
parameter check code into the attribute file.
Added such parameter check code in the appropiate
gl functions in gl.attrib and gl2.attrib

The shaders fail to compile if we don't omit those changes (Cordy game for example).
Anyways, they have no semantic meaning in GLSL, quote for GLSL 4.1 spec:
"Precision qualifiers are added for code portability with OpenGL ES, not for functionality. They have the
same syntax as in OpenGL ES, as described below, but they have no semantic meaning, which includes no
effect on the precision used to store or operate on variables."
Also removed an anoying print in the encoder.
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.

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.

This is the first commit for the GLESv1 implementation.
It also includes needed fixes in emugen to support const types.
Also, changed glFinish definition in gl.in to match the
definition as in gl.h.

glShaderSource strings are concatenated into a single string
before sent over the wire protocol. The wire protocol transfer is
done using a special api call 'glShaderString'
Change-Id: I90c157df66fe82fee17c460a1e7852d370c77088
Shader strings are sent over the wire protocal as one concatenated
string. a special api call - glShaderString is used to handle the
encoding and decoding of this string.
