Commit 1a339b6c(st/mesa: prefer native texture formats when possible)
introduced two new arguments to the st_choose_format() functions.
This patch fixes the order and passes the correct internal_target
rather than GL_NONE

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.

Instead of using a chain of manually maintained if/else blocks to
handle "#extension" directives, we now consult a table that specifies,
for each extension, the circumstances under which it is available, and
what flags in _mesa_glsl_parse_state need to be set in order to
activate it.
This makes it easier to add new GLSL extensions in the future, and
fixes the following bugs:
- Previously, _mesa_glsl_process_extension would sometimes set the
"_enable" and "_warn" flags for an extension before checking whether
the extension was supported by the driver; as a result, specifying
"enable" behavior for an unsupported extension would sometimes cause
front-end support for that extension to be switched on in spite of
the fact that back-end support was not available, leading to strange
failures, such as those in
https://bugs.freedesktop.org/show_bug.cgi?id=38015.
- "#extension all: warn" and "#extension all: disable" had no effect.
Notes:
- All extensions are currently marked as unavailable in geometry
shaders. This should not have any adverse effects since geometry
shaders aren't supported yet. When we return to working on geometry
shader support, we'll need to update the table for those extensions
that are available in geometry shaders.
- Previous to this commit, if a shader mentioned
ARB_shader_texture_lod, extension ARB_texture_rectangle would be
automatically turned on in order to ensure that the types
sampler2DRect and sampler2DRectShadow would be defined. This was
unnecessary, because (a) ARB_shader_texture_lod works perfectly well
without those types provided that the builtin functions that
reference them are not called, and (b) ARB_texture_rectangle is
enabled by default in non-ES contexts anyway. I eliminated this
unnecessary behavior in order to make the behavior of all extensions
consistent.

These were previously 1-bit-wide bitfields. Changing them to bools
has a negligible performance impact, and allows them to be accessed by
offset as well as by direct structure access.

From the OpenGL docs for GL_ARB_explicit_attrib_location:
This extension provides a method to pre-assign attribute locations to
named vertex shader inputs and color numbers to named fragment shader
outputs.
This was accidentally implemented for fragment shader inputs. This
patch fixes it to apply to fragment shader outputs.
Fixes piglit tests

The scissor state was incorrectly in a .prepare function instead of
.emit, so the packet would end up in the batch before the
STATE_BASE_ADDRESS. It appears that this doesn't actually hurt, as
the scissor address gets dereferenced according to the current SBA at
draw time.
All it's going to do is generate lots and lots and lots of
'warning: visibility attribute not supported in this configuration; ignored'
warnings

Considering fbdev as an in-kernel window system,
- opening a device opens a connection
- there is only one window: the framebuffer
- fb_var_screeninfo decides window position, size, and even color format
- there is no pixmap
Now EGL is built on top of this window system. So we should have
- the fd as the handle of the native display
- reject all but one native window: NULL
- no pixmap support
modeset support is still around, but it should be removed soon.
The system routine requires m0 be reserved for saving off architectural
state. Moved the allocation to start at 2 instead of 0.

Previously, if max_depth were 1, the following code would see the
first if-statement (correctly) not get flattened, but the second
if-statement would (incorrectly) get flattened:
void main()
{
if (a)
gl_Position = vec4(0);
if (b)
gl_Position = vec4(1);
}
This is because the visit_leave(ir_if*) method would not decrement the
depth before returning on the first if-statement.

Typically this was done by having a surface creation function fail if
the format was not supported.
However, in some situations when changing hardware surface formats,
it's desirable to do this check before attempting costly readback operations.
Also updated the surface_redefine interface.
Bump minor.
