glTexImage3D that caused me so many problems during the re-development
of the API scripts reared its ugly head again. This has been fixed by
tracking the parameter string for each entry-point individually.
This has the annoying side-effect that the names of the parameters in
all aliases of a function must be the same or gl_apitemp.py will
generate bad code. :( The changes in
src/mesa/glapi/{gl_API.xml,glapitable.h} and src/glx/x11/* are caused
by fixing the parameter names in various function aliases that didn't
match.

Romanick for pointing it out. Please review.

src/mesa/glapi. Basically, the scripts that did simple things (like
gl_offsets.py) were simple, and the scripts that did more complicated things
(like glX_proto_send.py) were getting progressively more and more out of
control. So, I re-write the foundation classes on which everything is based.
One problem with the existing code is that the division between the GL API
database representation and the way the output code is generated was either
blury or nonexistant. The new code somewhat follows the
Model-View-Controller pattern, minus the Controller. There is a distinct
set of classes that model the API data, and there is a distinct set of
classes that generate code from that data.
One big change is in the class that represents GL functions (was glFunction,
is now gl_function). There used to be an instance of this calls for each
function and for each alias to that function. For example, there was an
instance for PointParameterivSGIS, PointParameterivEXT, PointParameterivARB,
and PointParameteriv. In the new code, there is one instance. Each
instance has a list of entrypoint names for the function. In the next
revision, this will allow a couple useful things. The script will be able
to verify that the parameters, return type, and GLX protocol for a function
and all it's aliases match.
It will also allow aliases to be represented in the XML more compactly.
Instead of repeating all the information, an alias can be listed as:
<function name="PointParameterivARB" alias="PointParameterivEXT"/>
Because the data representation was changed, the order that the alias
functions are processed by the scripts also changed. This accounts for at
least 2,700 of the ~3,600 lines of diffs in the generated code.
Most of the remaining ~900 lines of diffs are the result of bugs *fixed* by
the new scripts. The old scripts also generated code with some bugs in it.
These bugs were discovered while the new code was being written.
These changes were discussed on the mesa3d-dev mailing list back at the end
of May:

fixes bugzilla #2747.
Remove the 'ignore="true"' from glVertexAttrib4bvARB. This fixes bugzilla
#2746.

for these extensions (as well as ARB_vertex_program and ARB_matrix_palette)
was just approved by the ARB on 8-Mar-2005. Now the only extension missing
for 1.5 support is ARB_vertex_buffer_object.
The opcodes for ARB_matrix_palette were also added to gl_API.xml. Since
this extension isn't supported by Mesa, no code is generated for it. Some
tabs were also converted to spaces in the comment for
GetCompressedTexImageARB.

setup_single_request, and setup_vendor_request to the global functions
__glXReadPixelReply, __glXReadReply, __glXSetupSingleRequest, and
__glXSetupVendorRequest. This will make it easier to add handcoded Single /
VendorPrivate / VendorPrivteWithReply functions.

code. With proper compiler optimization settings, it also decreases the
size of libGL.so by about 3KB.
