This is in preference to disconnected. If there's no other outputs
connected this will cause LVDS to be programmed even with the lid
closed rather than having X fail to start because of no available

Not entirely identical to 0x21, the per-encoder table header lacks the
third init table pointer. However, our current parsing of the table
should work just fine.

This makes this code common to both the nv04 and nv50 paths.
For the moment, we keep the previous behaviour with HDMI/eDP connectors
and report them as DVI-D/DP instead. This will be fixed once the rest
of the code has been fixed to deal with those types.

This commit breaks the userspace interface, and requires a new libdrm for
nouveau to operate again.
The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for
compatibility purposes are now gone, and replaced with the new ioctl which
allows for multiple push buffers to be submitted (necessary for hw index
buffers in the nv50 3d driver) and relocations to be applied on any buffer.
A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed
for userspace modesetting have also been removed.

This allows us to submit push buffers from any memtype to the hardware.
We'll need this ability for VRAM index buffers at some point.

PFIFO on G80 and up has a new mode where the main ring buffer is simply a
ring of pointers to indirect buffers containing the actual command/data
packets. In order to be able to implement index buffers in the 3D driver
we need to be able to submit data-only push buffers right after the cmd
packet header, which is only possible using the new command submission
method.
This commit doesn't make it possible to implement index buffers yet, some
userspace interface changes will be required, but it does allow for
testing/debugging of the hardware-side support in the meantime.

The nv50 pgraph handler (for example) could reenable pgraph fifo access
and that would be bad when pgraph context is being unloaded (we need the
guarantee a ctxprog isn't running).
