My merge of Mario's patch for this was botched. Fix it up so that OML
waits work correctly, and remove a bogus warning from ScheduleSwap.

The current code in I830DRI2ScheduleSwap() only schedules the correct
vblank events for the case divisor == 0, i.e., the simple
glXSwapBuffers() case.
In a glXSwapBuffersMscOML() request, divisor can be > 0, which would go
wrong.
This modified code should handle target_msc, divisor, remainder and the
different cases defined in the OML_sync_control extension correctly for
the divisor > 0 case.
It also tries to make sure that the effective framecount of swap
satisfies all constraints, taking the 1 frame delay in pageflipping mode
and possible delays in blitting/exchange mode due to
DRM_VBLANK_NEXTONMISS into account.
The swap_interval logic in the X-Servers DRI2SwapBuffers() call expects
the returned swap_target from the DDX to be reasonably accurate,
otherwise implementation of swap_interval for the glXSwapBuffers() as
defined in the SGI_swap_interval extension may become unreliable.
For non-pageflipped mode, the returned swap_target is always correct due
to the adjustments done by drmWaitVBlank(), as DRM_VBLANK_NEXTONMISS is
set.
In pageflipped mode, DRM_VBLANK_NEXTONMISS can't be used without severe
impact on performance, so the code in I830DRI2ScheduleSwap() must make
manual adjustments to the returned vbl.reply.sequence number.
This patch adds the needed adjustments.

Previous code only handled divisor == 0 case correctly. This should
honor a given target_msc for the divisor > 0 case and handle the
(msc % divisor) == remainder constraint correctly.

If a drawable isn't visible due to DPMS or redirection, we'll just blit
it rather than schedule a swap event. However, we didn't reset the
target_msc, so the swap target we receive from the server could get out
of sync with the vblank count of the drawable's display. So at DPMS on
time, the swap target would be the last good vblank count plus some
large number (since the swaps won't have been throttled).
Solve this by zeroing out the swap target like we should when we fall
back to a blit. Also make the kernel error cases more friendly by
making them fall back to blits too.

In the long long ago, fbOffset was used for DGA. The server now has
only one reference to fbOffset, a leftover setting of it in fbdevhw.
We can safely ignore it now, which is good since we weren't updating
it in other places where the front buffer offset could change.
We know that it's clobbered at each batchbuffer, anyway. And even if
this server isn't running DRI2, it can still be clobbered at batch
start in the KMS world.
The code was using uint32_t where an XID (currently an unsigned long)
was specified in the prototype. Use XID to avoid both the warning and
any potential problem.
The previous code made no sense, (multiplying an offset by 4 is
meaningless). It could have onlt worked with the offset being
fortuitously 0.

Like with the per context stuff, also drop the now artificial limit

There's now not a reason anymore to limit the number of active contexts.
So kill this accounting, too.
With that all gone, per-context state in the ddx is nil, so rip out

Cache coherency is now fully under the control of gem.
For lack of hw documentation, I had to find out the correct cache
placements by trial and error:
Backward and forward surfaces: I915_GEM_DOMAIN_RENDER
Correlation data: I915_GEM_DOMAIN_SAMPLER
Changing any of them leads to visual corruptions, so I think these
are the correct ones.

I've decided to allocate a new buffer for every render command, to
prevent stalling for the gpu. libdrm bo reuse should take care of
not wasting memory in case the buffer is not busy.
Also always emit the full state, it's not worth it to complicate
the code over a few stores to wc memory.

This also starts to kill the last remnants of the support for
physical addresses for the indirect state buffers. With gem this
would need kernel support (in the form of a new reloc type in
execbuf2).
This does not change the ABI between ddx and client libIntelXvMC.
I've decided to do this in one swoop when all the buffer rework is
done.

Seems to be a remnant from i810 XvMC support. last_flip is always 0,
so serves no real purpose anymore. Kill it and the associated code.
With last_flip gone, last_render also lost its purpose. Kill it, too.

This is in preparation for real relocatable drm_bo's instead
of memory at a fixed address. By switching to the batchbuffer
macros (like i965 xvmc) we can use the nice OUT_RELOC macro.
Also align the code more with coding-style elsewhere, i.e. bitops
instead of bitfield structures. The bitfield structures are
quite a mess to work with the batchbuffer macros, so they were
getting in the way, anyway.
