GLX was built specially and before Mesa core because libglapi.a could
not be built with IN_DRI_DRIVER defined.  This is no longer the case
since 6e99e6ddbf.

It works fine in my (limited) testing with both direct and indirect
rendering.  I also compare the outputs after preprocessing (gcc -E) with
or without this commit, and they are identical.

Install EGL drivers to EGL_DRIVER_INSTALL_DIR, which is default to
${libdir}/egl.

Simply the name to egl.

The swrast winsys always returns NULL when drm_api_create is called.

The egl_g3d state tracker has support for KMS, and the support is based
on the egl state tracker.  As egl_g3d provides more features, it should
be better to keep only egl_g3d to unify the efforts.

They do not build for a long while and there seems to be no active
users.  It might be better for them to live in the git histroy.

Need to use $CC for a shell variable, not $(CC) for a make variable
which the shell interprets as running the command "CC".

Do the auto trick that is used for both i915, i965 and svga.

Roll the glproto check into the dri2proto and libdrm check so we get the
proper CFLAGS and LDFLAGS for the package.

mesa/es should be built before the es state trackers.  This is done by
separating those that need to be built early from SRC_DIRS to CORE_DIRS.
The new variable is not exported, and will be prepended to SRC_DIRS.

The new EGL drivers use egl_g3d and respect EGL_DISPLAYS.  They are
named after the display supported and the DRM name.

This new (intermediate) EGL state tracker is the base work for EGL
drivers that uses Gallium.  It makes it easier to support new window
systems.

Currently, there is support only for X11.  This driver supports multiple
APIs (OpenVG, OpenGL, ...) and supports hardware acceleration through
winsys/drm.

This was a silent dependency before, but now we really need 1.4.11 for
INTEL_swap_event support, so check for it.

This allows libEGL to be built as a static library and removes libX11
from the dependencies.

Support the new DRI2 protocol request, DRI2SwapBuffers, in both direct
and indirect rendering context.  This request allows the display server
to optimize back->front swaps (e.g. through page flipping) and allows us
to more easily support other GLX features like swap interval and the OML
sync extension in DRI2.

The shell case statement obviously only evaluates the first matching
block.  Thanks to Julien Cristau for spotting the bug.

mesa/es is needed in SRC_DIRS to build es state tracker.

This adds missing pkg-config lookup for intel and moves the radeon
lookup into a case...esac so it's only looked up when one or more of
the radeon drivers are enabled.

We have all functions that need to be visible marked with PUBLIC and
this is trimming around 4% off the DRI driver .so size.

This change enabled gallium dri drivers by default under the
configure build system. Xorg drivers are built automaticaly
if a Xorg dev enviroment is installed and the Xorg version
is higher then 1.6.0.

Using a hack in the configure script the gallium intel
drivers have 3 options. Off, nothing is built. On, the
driver and binaries are built. Auto, only the driver but
not the binaries and winsys is built.

Since the i915g driver builds everywhere its can enable
the driver per default, so we can get build coverage.
But building the binaries per default is a pain for
distributions and testers since they conflict on the
install target with the old mesa drivers. Which are more
stable/faster/better.

So this change gives us the best of both worlds.

Hm. I could have said "chew trident and spit it out," or perhaps
"spear trident," instead. Dohoho.

As per FDO #17889.

AIX uses ".a" for both static and shared library extensions.

Not all drivers require the latest version, but distros are good at
tracking it since we've got a good record as far as not regressing, and
it sure beats having a weird compile failure in someone else's driver
later on.

	None of the other driver have a silly sufix,
	so just drop it. Nothing new added in this commit
	or any other commit but this is better marketing.

When cross compiling on a 64bit machine, gen_matypes.c is build
for the host machine (64bit) but must generates code for the target
machine (32bit). This causes wrong offsets all over the place and
crashes googleearth on my machine. Solution is to add -m32 when
cross compiling.

Attached patch is compatible with linux-x86-32 and autoconf based
builds.

This adds two --with configure options for setting defines for
MAX_WIDTH and MAX_HEIGHT.  It's conceivably just as easy to define
these in CFLAGS manually, but this way users don't need to know
about internal Mesa details.

Patch updated by BrianP to set DEFINES, not CFLAGS.

Since the drivers we produce on systems where we use
configure depend on none stable kernel API the driver
deliverables should not be built by default in the
mesa 7.7 release.

People wishing to shoot them self in the foot have to
pull the trigger themself, we just hand them the gun.

	This driver does no transformation of the gallium calls
	going to the real driver, like the identity matrix. It is
	intended to be the basis for transforming and/or debug
	drivers like trace and rbug.

	Authors of this patch are:
		Michal Krol, orignal heavy lifting.
		José Fonesca, object wrapping code stolen from trace.
		Jakob Bornecrantz, put it all toghether and renamed a stuff.
