Discontinue use of the old GetBuffeSize interface. Track both the
current read-drawable and the current draw-drawable. After moving
some context state to via_rednerbuffer, GLX_SGI_make_current_read can
be enabled.
The extension works, but the wincopy test prodcues a black window for
the destination window. After messing around with the window and
looking at the code, I believe the problem is in the handling of
buffer swap requests on a drawable that isn't the current draw-drawable.

The coordinates need to be computed after we've got the hw lock.
Code updated to:
1. Ignore all/x/y/width/height/ params passed to Clear func.
2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.

that are currently obtained via glXGetProcAddress and all of the XF86DRI
functions are replaced with a funciton table. This table will be passed to
__driCreateNewScreen.
One of the functions in the table is getProcAddress. This allows some
loaders to expose functionality not in all loaders. This will be immediatly
used for glxEnableExtension (formerly known to drivers as
__glXScrEnableExtension). libGL (and in the future libglx) expose this
function so that drivers can enable GLX extensions. libEGL should exposed
eglEnableExtension to enable EGL extensions. The same function cannot be
used for both because the extensions have different names and (possibly)
different semantics. Drivers can optionally use one, both, or neither.
The key parts are in the __DRIinterfaceMethodsRec structure in
dri_interface.h. A pointer to one of these structures is passed into
__driCreateNewScreen. Because of this, the version of the API is bumped to
20050725. Since the previous version(s) were never in a release, their
existance is erased.
I was actually a little surprised by how much code this cuts from the
drivers. A lot of glXGetProcAddress calls disappear, and a lot of
version checks go with them. Nice.
The one thing I'm not sure of is removing __glXInitialize. For some
reason that function was in the glXGetProcAddress table, but *nothing*
in the Mesa tree used it. Did something with DRI conf. use this
function? It seems odd...

Main driver impacts:
- new code for creating the Mesa GLframebuffer
- new span/pixel read/write code
Some drivers not yet updated/tested.

1. Unlock hardware before aborting and dumping DMA buffers. Otherwise display system may deadlock.
2. Fix DMA init IOCTL call that got mixed up in one of the previous commits.
3. Fix AGP command alignment

Bring in the IRQ handler and Ring buffer code, but ring buffer is disabled
as it is with the Xserver. It certainly locks up the CLE266.

Fix various mishandling of cliprects.
Allow multiple primitives to be emitted to a single dma buffer, which
was largely impossible previously.
Re-enable the fast unclipped render stage.

- Remove via duplicates of shared template files
- Update driver to work with current versions of the above
- Rework dma accounting
- Rework emitting to dma to use a consistent set of macros
The handling of cliprects in the driver is still pretty questionable.

Fix up the pageflipping code. This works now but is totally oblivious
to the X server (ie. it works but it's broken). Turned off by a #define.

Updated the driver to the new VIA security mechanisms in DRM. All command
submissions now passes through DRM ioctls. If the DRM AGP ring-buffer is
not enabled, it will use a DRM mechanism for submitting commands to the
hardware via a PCI bus mechanism.
Removed all direct write accesses to the hardware. Among other things the
VQ was previously turned off for the PCI path, apparently for Tuxracer.
That seemed unneeded and was removed. No visible impact on Tuxracer.
Abstracted all buffer blit operations in via_ioctl.c. The blitter context
is now reprogrammed before each blitting operation.
Updated driver date and drm version requirement.
