mesa, mesa/st: handle read color clamping properly
(I'll squash the st/mesa part to a separate commit. -Marek)
We set IMAGE_CLAMP_BIT in the caller based on _ClampReadColor, where
the operation mandates it.
TODO: did I get the set of operations mandating it right?

mesa: clamp color queries if and only if fragment clamping is enabled
commit 9940a3e31c2fb76cc3d28b15ea78dde369825107

mesa: introduce derived _ClampXxxColor state resolving FIXED_ONLY
To do this, we make ClampColor call FLUSH_VERTICES with the appropriate
_NEW flag.
We introduce _NEW_FRAG_CLAMP since fragment clamping has wide-ranging
effects, despite being in the Color attrib group.
This may be easily changed by s/_NEW_FRAG_CLAMP/_NEW_COLOR/g

mesa: add unclamped color parameters
makedepend would crash when a source includes a header indirectly, such
as
#define HEADER "some-header.h"
#include HEADER
Do not define HEADER (makedepend would detects this as an incomplete
include) and add the dependency manually in the Makefile.
This should hopefully fix bug #33374.
GLES can be enabled by running scons with
$ scons gles=yes
When gles=yes is given, the build is changed in three ways. First,
libmesa.a will be built with FEATURE_ES1 and FEATURE_ES2. This makes
DRI drivers and libEGL support and advertise GLES support. Second, GLES
libraries will be created. They are libGLESv1_CM, libGLESv2, and
libglapi. Last, libGL or opengl32 will link to libglapi. This change
is required as _glapi_* will be declared as __declspec(dllimport) in
libmesa.a on windows. libmesa.a expects those symbols to be defined in
another DLL. Due to this change to GL, GLES support is marked
experimental.
Note that GLES requires libxml2-python to generate some of its sources.
When --enable-shared-glapi is specified, libGL will share libglapi with
OpenGL ES instead of defining its own copy of glapi. This makes sure an
app will get only one copy of glapi in its address space.
The new option is disabled by default. When enabled, libGL and libglapi
must be built from the same source tree and distributed together. This
requirement comes from the fact that the dispatch offsets used by these
libraries are re-assigned whenever GLAPI XMLs are changed.
For GLX, indirect rendering for has_different_protocol() functions is
tricky. A has_different_protocol() function is assigned only one
dispatch offset, yet each entry point needs a different protocol opcode.
It cannot be supported by the shared glapi. The fix to this is to make
glXGetProcAddress handle such functions specially before calling
_glapi_get_proc_address.
Note that these files are automatically generated/re-generated
src/glx/indirect.c
src/glx/indirect.h
src/mapi/glapi/glapi_mapi_tmp.h
Move _glapi_* symbols from libGLESv1_CM.so and libGLESv2.so to
libglapi.so. This makes sure an app will get only one copy of glapi in
its address space.
Note that with this change, libGLES* and libglapi must be built from the
same source tree and distributed together. This requirement comes from
the fact that the dispatch offsets used by these libraries are
re-assigned whenever GLAPI XMLs are changed.
gl_and_es_API.xml defines OpenGL ES 1.1 and 2.0 API as well as OpenGL
API. It consists of gl_API.xml and the newly added es_EXT.xml,
ARB_get_program_binary.xml, OES_single_precision.xml, and
OES_fixed_point.xml.
Rename MAPI_GLAPI_SOURCES to MAPI_UTIL_SOURCES. Rename macro
MAPI_GLAPI_CURRENT to MAPI_MODE_UTIL. Update the comments to make it
clear that mapi may be used in two ways and how.
Fixes nasty bug where some parts of the code didn't define WIN32_THREADS
and were using the integer mutex implementation, causing even confusion
to the debuggers.
And there is little interest of other thread implemenation on Win32
besides Win32 threads.
This code was for the old GLcore build of the software rasteriser. The
X server switched to a DRI driver for software indirect GLX long ago.

Use scons target and dependency system instead of ad-hoc options.
Now is simply a matter of naming what to build. For example:
scons libgl-xlib
scons libgl-gdi
scons graw-progs
scons llvmpipe
and so on. And there is also the possibility of scepcified subdirs, e.g.
scons src/gallium/drivers
If nothing is specified then everything will be build.
There might be some rough corners over the next days. Please bare with me.
Move defines in glapioffsets.h to glapidispatch.h. Rename
_gloffset_FIRST_DYNAMIC to _gloffset_COUNT, which is equal to the number
of entries in _glapi_table.
Consistently use SET_by_offset, GET_by_offset, CALL_by_offset, and
_gloffset_* to recursively define all SET/GET/CALL macros.
glapioffsets.h exists for the same reason as glapidispatch.h does. It
is of no use to glapi. This commit also drops the use of glapioffsets.h
in glx as glx is considered an extension to glapi when it comes to
defining public GL entries.
glapidispatch.h exists so that core mesa (libmesa.a) can be built for
DRI drivers or for non-DRI drivers as a compile time decision (whether
IN_DRI_DRIVER is defined). It is of no use to glapi. This commit also
drops the use of glapidispatch.h in glx and libgl-xlib as they are
considered extensions to glapi when it comes to defining public GL
entries.
A number of other files had to be updated as well because const
qualifiers were added to the glMultiDrawArrays() function.
Also, GL_FIXED is now defined in glext.h.
This reverts commit b9abc6139a and the
follow on fixes (7aae704 and 6fe1b47). It's changing the glapi/driver
ABI and causes a number of problems for debug/non-debug builds.
There's a useful feature buried in glapi to log all API calls to stderr.
Unfortunately it requires editing the code and then it's enabled
unconditionally for that build. This patch builds in API logging for
debug builds and makes it run-time switchable by setting MESA_DEBUG=dispatch.
glapi defines an interface that is used by DRI drivers. It must not be
changed in an ABI incompatible way. This commit moves all
functions/variables belong to the interface to glapi.h. Instead of
including u_current.h from glapi.h, u_current.h now includes glapi.h.
Specifically, move all or most of
glapi/glapi.c to mapi/u_current.c,
glapi/glapi_execmem.c to mapi/u_execmem.c,
glapi/glthread.[ch] to mapi/u_thread.[ch]
and remove their dependencies on core Mesa headers.
