[Mesa-dev] glapi dispatch table isn't built correctly with --shared-glapi

[Jon TURNEY]

This is with git master, but the same issue exists since at least mesa-7.11.2.

./configure --enable-shared-glapi --disable-driglx-direct --with-driver=dri
--with-dri-drivers=swrast --with-gallium-drivers=swrast

$ gdb --args ./glean -r foo -o -t vertProg1 --quick
...
(gdb) b __indirect_glProgramParameters4fvNV
Function "__indirect_glProgramParameters4fvNV" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y

(gdb) r

Note that glean is calling glGenPrograms, but we are ending up in
glProgramParameters4fvNV.

It seems the indirect dispatch table isn't being built correctly.  The
dispatch table layouts in glapi_map_tmpi.h and glapitable.h are inconsistent
when buiding shared glapi, as shared-glapi/glapi_mapi_tmp.h is generated from
gl_and_es_API.xml, whereas glapitable.h is generated from gl_API.xml
