gallium: support for array textures and related changes

resources have a array_size parameter now.
get_tex_surface and tex_surface_destroy have been renamed to create_surface
and surface_destroy and moved to context, similar to sampler views (and
create_surface now uses a template just like create_sampler_view). Surfaces
now really should only be used for rendering. In particular they shouldn't be
used as some kind of 2d abstraction for sharing a texture. offset/layout fields
don't make sense any longer and have been removed, width/height should go too.
surfaces and sampler views now specify a layer range (for texture resources),
layer is either array slice, depth slice or cube face.
pipe_subresource is gone array slices (or cube faces) are now treated the same
as depth slices in transfers etc. (that is, they use the z coord of the
respective functions).

    gallium: rename element_offset/width fields in views to first/last_element

    This is much more consistent with the other fields used there
    (first/last level, first/last layer).
    Actually thinking about removing the ugly union/structs again and
    rename first/last_layer to something even more generic which could also
    be used for buffers (like first/last_member) without inducing headaches.

    gallium: remove PIPE_SURFACE_LAYOUT_LINEAR definition

    This was only used by the layout field of pipe_surface, but this
    driver internal stuff is gone so there's no need for this driver independent
    layout definition neither.

    gallium: separate depth0 and array_size in the resource itself.

    These fields are still mutually exclusive (since no 3d array textures exist)
    but it ultimately seemed to error-prone to adapt all code accept the new
    meaning of depth0 (drivers stick that into hardware regs, calculate mipmap
    sizes etc.). And it isn't really cleaner anyway.
    So, array textures will have depth0 of 1, but instead use array_size,
    3D textures will continue to use depth0 (and have array_size of 1). Cube
    maps also will use array_size to indicate their 6 faces, but since all drivers
    should just be fine by inferring this themselves from the fact it's a cube map
    as they always used to nothing should break.

    gallium: more interface changes

    In particular to enable usage of buffers in views, and ability to use a
    different pipe_format in pipe_surface.
    Get rid of layout and offset parameter in pipe_surface - the former was
    not used in any (public) code anyway, and the latter should either be computed
    on-demand or driver can use subclass of pipe_surface.
    Also make create_surface() use a template to be more consistent with
    other functions.

    this also changes flush_frontbuffer to use a pipe_resource instead of

    an abstraction for standalone 2d images which get passed around.
    (This has also implications for the non-rendering state-trackers.)

    gallium: interface changes for array textures and related cleanups

    This patch introduces array textures to gallium (note they are not immediately
    usable without the associated changes to the shader side).
    Also, this abandons pipe_subresource in favor of using level and layer
    parameters since the distinction between several faces (which was part of
    pipe_subresource for cube textures) and several z slices (which were not part
    of pipe_subresource but instead part of pipe_box where appropriate for 3d
    textures) is gone at the resource level.
    Textures, be it array, cube, or 3d, now use a "unified" set of parameters,
    there is no distinction between array members, cube faces, or 3d zslices.
    This is unlike d3d10, whose subresource index includes layer information for
    array textures, but which considers all z slices of a 3d texture to be part
    of the same subresource.
    In contrast to d3d10, OpenGL though reuses old 2d and 3d function entry points
    for 1d and 2d array textures, respectively, which also implies that for instance
    it is possible to specify all layers of a 2d array texture at once (note that
    this is not possible for cube maps, which use the 2d entry points, although
    it is possible for cube map arrays, which aren't supported yet in gallium).
    This should possibly make drivers a bit simpler, and also get rid of mutually
    exclusive parameters in some functions (as z and face were exclusive), one
    potential downside would be that 3d array textures could not easily be supported
    without reverting this, but those are nowhere to be seen.

    Also along with adjusting to new parameters, rename get_tex_surface /
    tex_surface_destroy to create_surface / surface_destroy and move them from
    screen to context, which reflects much better what those do (they are analogous
    to create_sampler_view / sampler_view_destroy).

    PIPE_CAP_ARRAY_TEXTURES is used to indicate if a driver supports all of this
    functionality (that is, both sampling from array texture as well as use a range
    of layers as a render target, with selecting the layer from the geometry shader).
