This helper function is used during mipmap generation to prepare space
for the destination mipmap levels.
This improves/fixes two things:
1. If the texture object was created with glTexStorage2D, calling
_mesa_TexImage2D() to allocate the new image would generate
INVALID_OPERATION since the texture is marked as immutable.
2. _mesa_TexImage2D() always frees any existing texture image memory
before allocating new memory. That's inefficient if the existing
image is the right size already.

Namely:
- EXT_transform_feedback
- ARB_transform_feedback2
- ARB_transform_feedback_instanced
The old interface was not useful for OpenGL and had to be reworked.
This interface was originally designed for OpenGL, but additional
changes have been made in order to make st/d3d1x support easier.
The most notable change is the stream-out info must be linked
with a vertex or geometry shader and cannot be set independently.
This is due to limitations of existing hardware (special shader
instructions must be used to write into stream-out buffers),
and it's also how OpenGL works (stream outputs must be specified
prior to linking shaders).
Other than that, each stream output buffer has a "view" into it that
internally maintains the number of bytes which have been written
into it. (one buffer can be bound in several different transform
feedback objects in OpenGL, so we must be able to have several views
around) The set_stream_output_targets function contains a parameter
saying whether new data should be appended or not.
Also, the view can optionally be used to provide the vertex
count for draw_vbo. Note that the count is supposed to be stored
in device memory and the CPU never gets to know its value.
OpenGL way | Gallium way
------------------------------------
BeginTF = set_so_targets(append_bitmask = 0)
PauseTF = set_so_targets(num_targets = 0)
ResumeTF = set_so_targets(append_bitmask = ~0)
EndTF = set_so_targets(num_targets = 0)
DrawTF = use pipe_draw_info::count_from_stream_output
v2: * removed the reset_stream_output_targets function
* added a parameter append_bitmask to set_stream_output_targets,
each bit specifies whether new data should be appended to each
buffer or not.
v3: * added PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME for ARB_tfb2,
note that the draw-auto subset is always required (for d3d10),
only the pause/resume functionality is limited if the CAP is not
advertised
v4: * update gallium/docs
v5: * compactified struct pipe_stream_output_info, updated dump/trace

It's like DrawArrays, but the count is taken from a transform feedback
object.
This removes DrawTransformFeedback from dd_function_table and adds the same
function to GLvertexformat (with the function parameters matching GL).
The vbo_draw_func callback has a new parameter
"struct gl_transform_feedback_object *tfb_vertcount".
The rest of the code just validates states and forwards the transform
feedback object into vbo_draw_func.

Backends indicate that they support this extension by returning
EGL_TRUE when native_display::get_param() is called with
NATIVE_PARAM_PRESENT_REGION and NATIVE_PARAM_PRESERVE_BUFFER.
native_present_control is extended to include the region that should
be presented. When native_present_control::num_rects is zero,
the whole surface is to be presented.

Now that we have miptrees for everything, we can more easily test for
!has_separate_stencil completeness. Also, test for whether the
stencil rb is the wrong kind of format for separate stencil, or if we
are trying to do packed to different images of a single miptree.

Now there's the thing that CALLOCs and sets up window system vtable,
and the thing that CALLOCs and sets up user renderbuffer vtable. The
user renderbuffer vtable gets replaced later by
intel_renderbuffer_update_wrapper for wrapped renderbuffers (things
with name == ~0).

The cool part was that in the "fbo-depthstencil -drawpixels
GL_DEPTH24_STENCIL8 32F_24_8_REV" testcase, the shifting happened to
end up with a value awfully close to the expected value, except for
every other pixel being 0 (the stencil value, shifted away to
nothing).

Invalid shaders containing the character % at an unexpected location
would cause Bison to call yyerror with a message of:
syntax error, unexpected '%'
Bison expects yyerror() to take a string, while _mesa_glsl_error() is a
printf-style function. This hit the classic printf string escape issue:
_mesa_glsl_error(loc, state, "unexpected '%'"); // invalid!
_mesa_glsl_error(loc, state, "%s", "unexpected '%'"); // correct.
This caused assertion failures after ralloc_asprintf_append called
vsnprintf to determine the length of the text that would be printed:
vsnprintf would see the invalid format and return -1, an invalid length.
The solution is to define a proper yyerror() wrapper function that calls
_mesa_glsl_error with the "%s". Since we compile with -p "_mesa_glsl",
yyerror is defined as:
#define yyerror _mesa_glsl_error
So we have to #undef yyerror in order to be able to declare it.

glx: Remove swap barrier and hyperpipe support
Never implemented in any open source driver. The implementation
assumed explicit DDX driver knowledge of how the client-side driver
worked, since at the time the server's GL renderer was not a DRI driver.
But now, it is, so any implementation of these should be done with
additional DRI driver API, like the swap control extension.
