This patches add MESA_copy_sub_buffer support to the dri sw loader and
then to gallium state tracker, llvmpipe, softpipe and other bits.
It reuses the dri1 driver extension interface, and it updates the swrast
loader interface for a new putimage which can take a stride.
I've tested this with gnome-shell with a cogl hacked to reenable sub copies
for llvmpipe and the one piglit test.
I could probably split this patch up as well.
v2: pass a pipe_box, to reduce the entrypoints, as per Jose's review,
add to p_screen doc comments.
v3: finish off winsys interfaces, add swrast classic support as well.

Commit b77316ad75
st/dri: always copy new DRI front and back buffers to corresponding MSAA buffers
introduced creating a pipe_context for every call to validate, which is not required
because the callers have a context anyway.
Only exception is egl_g3d_create_pbuffer_from_client_buffer, can someone test if it
still works with NULL passed as context for validate? From examining the code I
believe it does, but I didn't thoroughly test it.

The flag is currently only generated by st/dri on SwapBuffers.

There seems to have been two different ways to communicate the

remove the profile flags and use ST_PROFILE_DEFAULT (compatibility

instead.
Also change the values of the ST_CONTEXT_FLAG_DEBUG and

The api and the state tracker manager code as well as the state tracker code
assumed that only a single context could be bound to a drawable. That is not
a valid assumption, since multiple contexts can bind to the same drawable.
Fix this by making it the state tracker's responsibility to update all
contexts binding to a drawable
Note that the state trackers themselves don't use atomic stamps on
frame-buffers. Multiple context rendering to the same drawable should
be protected by the application.

The drivers have been changed so that they behave as if all of the flags
were set. This is already implicit in most hardware drivers and required
for multiple contexts.
Some state trackers were also abusing the PIPE_FLUSH_RENDER_CACHE flag
to decide whether flush_frontbuffer should be called.
New flag ST_FLUSH_FRONT has been added to st_api.h as a replacement.
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).

rename first/last_layer to something even more generic which could also

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.

Get rid of layout and offset parameter in pipe_surface - the former was

on-demand or driver can use subclass of pipe_surface.
Also make create_surface() use a template to be more consistent with
other functions.

util: adapt to interface changes
amazing how much code changes just due to some subtle interface changes?

gallium: more interface fail, docs
this also changes flush_frontbuffer to use a pipe_resource instead of
a pipe_surface - pipe_surface is not meant to be (or at least no longer)
an abstraction for standalone 2d images which get passed around.
(This has also implications for the non-rendering state-trackers.)

gallium: fix array texture interface changes bugs, docs

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).
Fixes this GCC warning.

Allows applications to dump surfaces to file without
referencing gallium/auxiliary entry points statically.
Existing test apps have been modified such that
they save the contents of the fronbuffer only
when the `-o' option's specified.
Add struct st_context_attribs to describe context profiles and
attributes. Modify st_api::create_context to take the new struct
instead of an st_visual.
st_context_attribs can be used to support GLX_ARB_create_context_profile
and GLX_EXT_create_context_es2_profile in the future. But the
motivation for doing it now is to be able to replace ST_API_OPENGL_ES1
and ST_API_OPENGL_ES2 by profiles.
Having 3 st_api's to provide OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is
not a sane abstraction, since all of them share glapi for current
context/dispatch management.
Keith prefers a clean separation between graw applications and
implementations, where apps do not link libgallium.a but instead
get all functionality they need via graw interface.
Although this is not incompatible with late loading of graw drivers, it
it would make it very hard to maintain, as wrappers for every utility
symbol exposed in graw would have to be written or generated somehow.
This allows to build multiple graws libs simultaneously and avoid
unnecessary rebuilds of the tests.
Also remove graw_util.c from inside the graw implementation -- it was
only being provided by one implementation, and graw tests were linking
against gallium anyway.
The callback is used by st/vega to check if a visual specifies the
depth/stencil format. It forces st/vega to be loaded by st/egl to
perform the check. As noted in EGL spec, the depth/stencil format of a
visual should not affect OpenVG. It should be better to ignore the
field and always allocate the depth/stencil texture.
This interfacre replaces the drm_api api it works very much the same
way as drm_api but with the exception that its meant for the target
to implement it. And it does not export a get function and neither a
destroy function.
