Mesa core doesn't need to have mapi sanity check that our aliases all map
to the same offset. That's a build-time decision.

On Linux, the static glapi path sees libGL.so implementing the static
glapi, and the drivers (libgallium_dri.so) updating/reading the TLS
vars.
On Windows, to allow libgallium_wgl.dll to be a full ICD, it's
responsible for implementing the actual static glapi. However, before
this change, OpenGL32.dll was also implementing the static glapi,
meaning that GL API calls from OpenGL32.dll didn't route to the driver
correctly because the TLS vars were never actually set - the driver set
its copy, and OpenGL32.dll read its own copy.
Now, always build a bridge and static version of glapi when not using
shared. The bridge version is linked into OpenGL32.dll, and the static
version is linked into the driver on Windows. GLES only builds with
shared glapi - but after this, shared glapi is not really needed on
Windows for GLES, since the driver has all of the data.

However they have to be called via _glapi_get_dispatch/context. This
would be safe to do on any platform, but the extra indirection is only
necessary on Windows since TLS vars can't be exported from a DLL.

Structurally, this is very similar to the existing Apple-DRI code, except I
have chosen to implement this using the __GLXDRIdisplay, etc. vtables (as
suggested originally in [1]), rather than a maze of ifdefs. This also means
that LIBGL_ALWAYS_SOFTWARE and LIBGL_ALWAYS_INDIRECT work as expected.

This adds:
* the Windows-DRI extension protocol headers and the windowsdriproto.pc
file, for use in building the Windows-DRI extension for the X server
* a Windows-DRI extension helper client library
* a Windows-specific DRI implementation for GLX clients
The server is queried for Windows-DRI extension support on the screen before
using it (to detect the case where WGL is disabled or can't be activated).
The server is queried for fbconfigID to pixelformatindex mapping, which is
used to augment glx_config.
The server is queried for a native handle for the drawable (which is of a
different type for windows, pixmaps and pbuffers), which is used to augment
__GLXDRIdrawable.
Various GLX extensions are enabled depending on if the equivalent WGL
extension is available.
Removes the public symbol _glapi_create_table_from_handle from
libGL.so.1.2.0 on all platforms except Darwin.
Since the symbol is not used on other platforms it makes sense to
build glapi_gentable.c only on Darwin.
As a side effect it accelerates the build a bit and reduces the size
of libGL.so.1.2.0 as follows:
size lib/libGL.so.1.2.0 on my system shows

_glapi_new_nop_table() creates a new dispatch table populated with
pointers to no-op functions.
_glapi_set_nop_handler() is used to register a callback function which
will be called from each of the no-op functions.
Now we always generate a separate no-op function for each GL entrypoint.
This allows us to do proper stack clean-up for Windows __stdcall and
lets us report the actual function name in error messages. Before this
change, for non-Windows release builds we used a single no-op function
for all entrypoints.

It was really only used in the radeon driver for a debug printf.
And evidently, libGL.so referenced it just to work around some sort
of linker issue.
This patch removes the two calls to the function and the function
itself.

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.
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.
