gallium/util: make util_copy_framebuffer_state(src=NULL) work
Be more consistent with the other u_inlines util_copy_xyz_state()
helpers and support NULL src.

gallium: Put no.of {samples,layers} into pipe_framebuffer_state
Here we store the number of samples and layers directly in the
pipe_framebuffer_state so that in the case of
ARB_framebuffer_no_attachment we may make use of them directly.
Further, we adjust various gallium/auxiliary helper functions
accordingly.
V2:
Convert branches in util_framebuffer_get_num_layers() and
util_framebuffer_get_num_samples() to their canonical form.
V3:
'git stash pop' the typo fix of 'cbufs' which should be
'nr_cbufs' that was missing in V2, woops! Thanks Marek for
pointing this out yet again.
V4:
Squash in the following patch:
'gallium/util: Ensure util_framebuffer_get_num_samples() is valid'
Upon context creation, internal driver structures are malloc()'ed
and memset() to zero them. This results in a invalid number of
samples 'by default'. Handle this in the simplest way to avoid
elaborate and probably equally sub-optimial solutions.

st/mesa: bind NULL colorbuffers as specified by glDrawBuffers
An example why it is required:
Let's say there's a fragment shader writing to gl_FragData[0..1].
The user calls: glDrawBuffers(2, {GL_NONE, GL_COLOR_ATTACHMENT0});
That means gl_FragData[0] is unused and gl_FragData[1] is written
to GL_COLOR_ATTACHMENT0.
st/mesa was skipping the GL_NONE draw buffer, therefore gl_FragData[0]
was written to GL_COLOR_ATTACHMENT0, which was wrong.
This commit fixes it, but drivers must also be fixed not to crash when
binding NULL colorbuffers. There is also a new set of piglit tests for this.
The MSAA state also had to be fixed not to crash when reading fb->cbufs[0].

gallium/util: implement layered framebuffer clear in u_blitter
All bound layers (from first_layer to last_layer) should be cleared.
This uses a vertex shader which outputs gl_Layer = gl_InstanceID, so each
instance goes to a different layer. By rendering a quad and setting
the instance count to the number of layers, it will trivially clear all
layers.
This requires AMD_vertex_shader_layer (or PIPE_CAP_TGSI_VS_LAYER), which only
radeonsi supports at the moment. r600 could do this too. Standard DX11
hardware will have to use a geometry shader though, which has higher overhead.

auxiliary: fix util_framebuffer_copy
util_framebuffer_copy was attempting to copy all elements of the
source framebuffer state.
However, this breaks if the user does not zero initialize the structure.
Instead, only copy the elements up to nr_cbufs, and clear elements up
to dst->nr_cbufs, if the destination was larger than the source.
