d3d1x: add new Direct3D 10/11 COM state tracker for Gallium

This is a new implementation of the Direct3D 11 COM API for Gallium.

Direct3D 10 and 10.1 implementations are also provided, which are
automatically generated with s/D3D11/D3D10/g plus a bunch of #ifs.

While this is an initial version, most of the code is there (limited
to what Gallium can express), and tri, gears and texturing demos
are working.

The primary goal is to realize Gallium's promise of multiple API
support, and provide an API that can be easily implemented with just
a very thin wrapper over Gallium, instead of the enormous amount of
complex code needed for OpenGL.

The secondary goal is to run Windows Direct3D 10/11 games on Linux
using Wine.
Wine dlls are currently not provided, but adding them should be
quite easy.

Fglrx and nvidia drivers can also be supported by writing a Gallium
driver that talks to them using OpenGL, which is a relatively easy
task.
Thanks to the great design of Direct3D 10/11 and closeness to Gallium,
this approach should not result in detectable overhead, and is the
most maintainable way to do it, providing a path to switch to the
open Gallium drivers once they are on par with the proprietary ones.

Currently Wine has a very limited Direct3D 10 implementation, and
completely lacks a Direct3D 11 implementation.

Note that Direct3D 10/11 are completely different from Direct3D 9
and earlier, and thus warrant a fully separate implementation.

The third goal is to provide a superior alternative to OpenGL for
graphics programming on non-Windows systems, particularly Linux
and other free and open systems.

Thanks to a very clean and well-though design done from scratch,
the Direct3D 10/11 APIs are vastly better than OpenGL and can be
supported with orders of magnitude less code and development time,
as you can see by comparing the lines of code of this commit and
those in the existing Mesa OpenGL implementation.

This would have been true for the Longs Peak proposal as well, but
unfortunately it was abandoned by Khronos, leaving the OpenGL
ecosystem without a graphics API with a modern design.

A binding of Direct3D 10/11 to EGL would solve this issue in the
most economical way possible, and this would be great to provide
in Mesa, since DXGI, the API used to bind Direct3D 10/11 to Windows,
is a bit suboptimal, especially on non-Windows platforms.

Finally, a mature Direct3D 10/11 implementation is intrinsically going
to be faster and more reliable than an OpenGL implementation, thanks
to the dramatically smaller API and the segregation of all nontrivial
work to object creation that the application must perform ahead of
time.

Currently, this commit contains:
- Independently created headers for Direct3D 10, 10.1, 11 and DXGI 1.1,
  partially based on the existing Wine headers for D3D10 and DXGI 1.0
- A parser for Direct3D 10/11 DXBC and TokenizedProgramFormat (TPF)
- A shader translator from TokenizedProgramFormat to TGSI
- Implementation of the Direct3D 11 core interfaces
- Automatically generated implementation of Direct3D 10 and 10.1
- Implementation of DXGI using the "native" framework of the EGL st
- Demos, usable either on Windows or on this implementation
  - d3d11tri, a clone of tri
  - d3d11tex, a (multi)texturing demo
  - d3d11gears, an improved version of glxgears
  - d3d11spikysphere, a D3D11 tessellation demo (currently Windows-only)
- A downloader for the Microsoft HLSL compiler, needed to recompile
  the shaders (compiled shader bytecode is also included)

To compile this, configure at least with these options:
--with-state-trackers=egl,d3d1x --with-egl-platforms=x11
plus some gallium drivers (such as softpipe with --enable-gallium-swrast)

The Wine headers (usually from a wine-dev or wine-devel package) must
be installed.
Only x86-32 has been tested.

You may need to run "make" in the subdirectories of src/gallium/winsys/sw
and you may need to manually run "sudo make install" in
src/gallium/targets/egl

To test it, run the demos in the "progs" directory.
Windows binaries are included to find out how demos should work, and to
test Wine integration when it will be done.

Enjoy, and let me know if you manage to compile and run this, or
which issues you are facing if not.

Using softpipe is recommended for now, and your mileage with hardware
drivers may vary.
However, getting this to work on hardware drivers is also obviously very
important.

Note that currently llvmpipe is buggy and causes all 3 gears to be
drawn with the same color.
Use export GALLIUM_DRIVER=softpipe to avoid this.

Thanks to all the Gallium contributors and especially the VMware
team, whose work made it possible to implement Direct3D 10/11 much
more easily than it would have been otherwise.

+/* This approach serves two purposes.

+ * count every time something is bound/unbound to the pipeline, since they are
+ * expensive.
+ * Fortunately, the immediate context can only be used by a single thread, so
+ * we don't have to use them, as long as a separate reference count is used
+ * (see dual_refcnt_t).
+ *
+ * Second, we want to avoid the Device -> DeviceContext -> bound DeviceChild -> Device
+ * garbage cycle.
+ * To avoid it, DeviceChild doesn't hold a reference to Device as usual, but adds
+ * one for each external reference count, while internal nonatomic_add_ref doesn't
+ * add any.
+ *
+ * Note that ideally we would to eliminate the non-atomic op too, but this is more
+ * complicated, since we would either need to use garbage collection and give up
+ * deterministic destruction (especially bad for large textures), or scan the whole
+ * pipeline state every time the reference count of object drops to 0, which risks
+ * pathological slowdowns.
+ *
+ * Since this microoptimization should matter relatively little, let's avoid it for now.
+ *
+ * Note that deferred contexts don't use this, since as a whole, they must thread-safe.
+ * Eliminating the atomic ops for deferred contexts seems substantially harder.
+ * This might be a problem if they are used in a one-shot multithreaded rendering
+ * fashion, where SMP cacheline bouncing on the reference count may be visible.
+ *
+ * The idea would be to attach a structure of reference counts indexed by deferred
+ * context id to each object. Ideally, this should be organized like ext2 block pointers.
+ *
+ * Every deferred context would get a reference count in its own cacheline.
+ * The external count is protected by a lock bit, and there is also a "lock bit" in each
+ * internal count.
+ *
+ * When the external count has to be dropped to 0, the lock bit is taken and all internal
+ * reference counts are scanned, taking a count of them. A flag would also be set on them.
+ * Deferred context manipulation would notice the flag, and update the count.
+ * Once the count goes to zero, the object is freed.
+ *
+ * The problem of this is that if the external reference count ping-pongs between
+ * zero and non-zero, the scans will take a lot of time.
+ *
+ * The idea to solve this is to compute the scans in a binary-tree like fashion, where
+ * each binary tree node would have a "determined bit", which would be invalidated
+ * by manipulations.
+ *
+ * However, all this complexity might actually be a loss in most cases, so let's just
+ * stick to a single atomic refcnt for now.
+ *
+ * Also, we don't even support deferred contexts yet, so this can wait.
