COPY_TRANSFER3D was designed to handle transfers
to host. This patch is making it possible to use
this CCMD in both directions.
If guest would like to have this data available
immediately, then it should encode, flush and wait on
the guest side.
The data is copied from host to iovec attached to resource.
In most cases resource is a staging buffer.

Add a new command associated to glLinkProgram. With this we should be
able to compile and link shaders when requested by the user.
Together with the command we expect an array of shader handles attached
to the program, where each position of the array corresponds to a pipe
shader type.

Although anisotropic filtering uses a float value, most hw doesn't
care below integer levels, so just transmit 1-16 for the sampler value
not the full float.

the protocol failed to handle larger shaders, this allow
the renderer to reassemble large shaders and recombined
the chunks before passing them to the GLSL translation.
This also enhances the renderer protocol to allow
for some more info in the shader object, and removes
the separate vs/gs/fs variants in favour of a type field
in the shader.
This fixes a number of issues with how transform feedback works
it does requires ARB_transform_feedback3 to work at all, but
hopefully this extension is widespread enough, if not we can
revisit later.
It uses transform feedback objects to store the stream out
state.
