The new code-generated version of _mesa_create_exec_table() populates
the entire dispatch table (except for dynamic functions) by itself; it
no longer calls separate functions to initialize parts of the dispatch
table. This patch removes those no-longer-needed functions.

This script generates the file api_exec.c, which contains just the
function _mesa_create_exec_table(), based on the XML files in
src/mapi/glapi/gen.
The following XML attributes, in particular, are used:
- "es1" indicates functions that should be available in ES1 contexts.
- "es2" indicates functions that should be available in ES2/ES3
contexts.
- "exec" indicates which Mesa function should be dispatched to. E.g.
if the GL function is glFoo(), then:
- exec="mesa" (the default) dispatches to _mesa_Foo().
- exec="check" dispatches to _check_Foo().
- exec="es" dispatches to _es_Foo().
- exec="loopback" dispatches to loopback_Foo().
- exec="skip" or exec="dynamic" causes this function to be skipped;
either it is not yet supported ("skip"), or its dispatch table
entry will be dynamically populated based on GL state ("dynamic").
- "desktop" indicates functions that should be available in desktop GL
(non-ES) contexts.
- "deprecated" indicates functions that should not be available in
core contexts.
- "mesa_name" indicates functions whose implementation in Mesa has a
different suffix than the corresponding GL function name.
The generated code looks roughly like this (showing just a single
statement in each block for brevity):
struct _glapi_table *
_mesa_create_exec_table(struct gl_context *ctx)
{
struct _glapi_table *exec;
exec = _mesa_alloc_dispatch_table(_gloffset_COUNT);
if (exec == NULL)
return NULL;
if (_mesa_is_desktop_gl(ctx)) {
SET_ActiveProgramEXT(exec, _mesa_ActiveProgramEXT);
/* other functions not shown */
}
if (_mesa_is_desktop_gl(ctx) || _mesa_is_gles3(ctx)) {
SET_BeginQueryARB(exec, _mesa_BeginQueryARB);
/* other functions not shown */
}
if (_mesa_is_desktop_gl(ctx) || ctx->API == API_OPENGLES) {
SET_GetPointerv(exec, _mesa_GetPointerv);
/* other functions not shown */
}
if (_mesa_is_desktop_gl(ctx) || ctx->API == API_OPENGLES || ctx->API == API_OPENGLES2) {
SET_ActiveTextureARB(exec, _mesa_ActiveTextureARB);

}
if (_mesa_is_desktop_gl(ctx) || ctx->API == API_OPENGLES2) {

gl_XML.py's gl_function class keeps track of an entry_point_api_map
property that tracks, for each set of aliased functions, which ES1 or
ES2 version the given function name first appeared in.
This patch aggregates that information together across aliased
functions, into an easier-to-use api_map property.
Future patches will use this information when code generating
_mesa_create_exec_table(), to determine which set of dispatch table
entries should be populated based on the API.

Some of the functions that we store in the dispatch table are declared
as non-static in their .c files and are inserted into the dispatch
table directly by _mesa_create_exec_table(). Other functions are
declared as static, and are inserted into the dispatch table by a
dedicated function that lives in the same .c file
(e.g. _mesa_loopback_init_api_table() in api_loopback.c).
This patch makes all of these functions non-static, and creates
appropriate prototypes for them, so that in future patches we can
populate the entire dispatch table using a single code-generated
function.

When the XML lists one or more GL api functions as aliases for another
GL function, the mesa function that implements the functionality is
usually named after the canonical version of the function (the one
that is the target of the aliases). For example, FogCoordd is listed
as an alias of FogCoorddEXT, and the Mesa function implementing the
functionality is called loopback_FogCoorddEXT.
However, there are exceptions. For example, Enablei is listed as an
alias of EnableIndexedEXT, but the Mesa function implementing the
functionality is called _mesa_EnableIndexed.
To account for these anomalies, this patch annotates the XML with
"mesa_name" attributes, which describe how to adjust the function name
to find the corresponding Mesa function.
For example:
<function name="EnableIndexedEXT" mesa_name="-EXT">...</function>
<function name="IsProgramNV" mesa_name="-NV+ARB">...</function>
means that EnableIndexedEXT is implemented by a Mesa function called
_mesa_EnableIndexed, and IsProgramNV is implemented by a Mesa function
called _mesa_IsProgramARB.
Future patches will use this annotation when code generating
_mesa_create_exec_table(), to determine the name of the Mesa function
that should be stored in each dispatch table entry.

The decompression is done in-place and only the compressed tiles are
decompressed. Note: R6xx-R7xx can do that only with Z16 and Z32F.
The texture unit is programmed to use non-displayable tiling and depth
ordering of samples, so that it can fetch the texture in the native DB format.
The latest version of the libdrm surface allocator is required for stencil
texturing to work. The old one didn't create the mipmap tree correctly.
We need a separate mipmap tree for stencil, because the stencil mipmap
offsets are not really depth offsets/4.
There are still some known bugs, but this should save some memory and it also
improves performance a little bit in Lightsmark (especially with low
resolutions; tested with Radeon HD 5000).
The DB->CB copy is still used for transfers.

The functions were broken, because they converted ints to floats.
Now we can finally advertise OpenGL 3.0. ;)
In this commit, the vbo module also tracks the type for each attrib
in addition to the size. It can be one of FLOAT, INT, UNSIGNED_INT.
The little ugliness is the vertex attribs are declared as floats even though
there may be integer values. The code just copies integer values into them
without any conversion.
This implementation passes the glVertexAttribI piglit test which I am going
to commit in piglit soon. The test covers vertex arrays, immediate mode and
display lists.
