This fixes a build error introduced with commit
"winsys/svga: Update to vmwgfx kernel module 2.1"
if both the svga driver and the xorg state tracker was enabled
at the same time.

If needed we can re-add a minimal target for basic functionality.

It may happen when two drivers share one winsys.

The backend calls null_sw_create() to create sw_winsys.  And that is
pretty much it...

Unused since removal of demos from the repository?

libGLw is an old OpenGL widget library with optional Motif support.
It almost never changes and very few people actually still care about
it, so we've decided to ship it separately.

The new home for libGLw is: git://git.freedesktop.org/mesa/glw/

EGL doesnt define howto manage different native platforms.
So mesa has a builtime configurable default platform,
whith non-standard envvar (EGL_PLATFORM) overwrites.
This caused unneeded bugreports, when EGL_PLATFORM was forgotten.

Detection is grouped into basic types of NativeDisplays (which itself
needs to be detected).  The final decision is based on characteristcs
of these basic types:

  File Desciptor based platforms (fbdev):
    - fstat(2) to check for being a fd that belongs to a character device
    - check kernel subsystem (todo)

  Pointer to structuctures (x11, wayland, drm/gbm):
    - mincore(2) to check whether its valid pointer to some memory.
    - magic elements (e.g. pointers to exported symbols):
      o wayland display stores interface type pointer (first elm.)
      o gbm stores pointer to its constructor (first elm.)
      o x11 as a fallback (FIXME?)

Building the VA state tracker only works when the header/libs are available.
Also add a warning that the state tracker is currently undmaintained.

Building the VDPAU state tracker only works when the header/libs are available.

Building the XvMC state tracker only works when the header/libs are available.

I think the past are those times when the gallium interface was changed all
the time. Now it is not, so there is no reason to always compile the libs
if they are not needed.

Only some targets need that, the others don't.

As Chia-I Wu said 'There are two libGL providers, Xlib and DRI based
they cannot coexist'

  $ ./configure --disable-driglx-direct \
                --with-dri-drivers=swrast \
                --with-gallium-drivers=

libdrm is used in multiple places.  Always check for it and set
have_libdrm.  Each user can then check the variable.

This is useful when only EGL and DRI drivers are needed.

Define GLX_INDIRECT_RENDERING and GLX_DIRECT_RENDERING when $enable_glx,
not $enable_dri.

The idea is that DRI driver, libGL and libOSMesa are libraries that can
be independently enabled, yet --with-driver does not allow us to easily
do that, if not impossible.  This also matches what
--enable-{egl,xorg,d3d1x} do for the respective libraries.

There are two libGL providers: Xlib-based and DRI-based.  They cannot
coexist.  To be able to choose between them, --enable-xlib-glx is also
added.

With this commit, --with-driver=dri can be replaced by

  $ ./configure --enable-dri --enable-glx --disable-osmesa

--with-driver=xlib can be replaced by

  $ ./configure --disable-dri --enable-glx --enable-osmesa \
                --enable-xlib-glx

and --with-driver=osmesa can be replaced by

  $ ./configure --disable-dri --disable-glx --enable-osmesa

Some combinations that cannot be supported with --with-driver will
produce errors at the moment.  But in the future, we would like to
support, for example,

  $ ./configure --enable-dri --disable-glx --enable-egl
  (build libEGL and DRI drivers, but not libGL)

Note that this commit still keeps --with-driver for transitional
purpose.

Build egl_gallium from targets/egl-static intead of targets/egl.  The
latter exposes (unversioned) gallium interfaces and is frowned upon.

So that gbm(_dri) which pulls in shared-glapi is not needed.

If --disable-gallium is passed, llvm-config isn't checked for, so mark
it explicitly as absent, through LLVM_CONFIG=no.

Passing --disable-gallium would result in:
| ../configure: line 9739: --version: command not found
| ../configure: line 9740: --cppflags: command not found
| ../configure: line 9741: --libs: command not found
| ../configure: line 9743: --ldflags: command not found

With this commit, one gets that instead:
