A new optional kms driver option "SwapbuffersWait" is defined
for xorg.conf, which defaults to "on". If "on", DRI2 bufferswaps
will be synchronized to vsync, otherwise not.
This currently only affects copy-swaps, not pageflipped swaps.
It also requires a swap_interval setting of zero by the OpenGL
client.
Ideally, we'd provide a way for dri2 to pass the current swap
interval to the ddx so we could change this dynamically.

- makes Xv more consistent with r1xx/r2xx/r6xx/r7xx
- Xv attributes like brightness, contrast, hue, etc. only work
when bicubic is disabled.
- avoids performance issues on some systems when sampling from textures
in GART with kms.
- It can be re-enabled with using xvattr

Now that the screen section mapping is fixed,
Make the option per-instance and allow multiple
outputs to be specified; e.g., DVI-0 and HDMI-0
associated with instance 0 and LVDS and VGA-0
associated with instance 1.
Allows users that want to use zaphod mode to select
which xrandr outputs are assigned to which head. E.g.,
Option "ZaphodHeads" "LVDS,VGA-0"
will assign LVDS to the first zaphod driver instance
and VGA-0 to the second instance.
This patch returns NULL for pixmap creation when we are using
mixed pixmaps and the pixmap has a size.
The size check is necessary for the front buffer.
We add a flag to force pixmap creation for certain pixmaps
that need to be hw, like the DRI2 and Xv ones.
Idea from Michel and workarounds from Ben Skeggs.
v2: add Option "EXALowVRAM" to allow configuring this, value in MBs.

This attribute allows the user to override which
crtc is synced with when XV_VSYNC is enabled. This
is useful for clone modes where the user can might want
to override the default.
Allows you to specify an edid per output from a file
to override what is detected by DDC. Useful for
problematic monitors or KVM switches that block
DDC. Specifying an EDID that is not compatible with
your monitor could damage your monitor so use with
caution.
agd5f: cache the custom edid at startup so we don't
have to read it from file every time the output is
queried.
- replaces DynamicClocks Option as the name was misleading
- unified interface for atom and com based bioses
- fix up clock gating code for newer r3xx asics
Thanks to Joseph Adams for helping me sort this out.
Verified on eMac G4/1.0 with radeon 7500
Later eMacs with radeon 9200 or 9600 chips may have
different ddc setups. Need to verify.
