nouveau: interface changes for 0.0.16 DRM

This commit encompasses the changes necessary to run on top of the 0.0.16
nouveau interface, additional APIs to support the new features of the
interface, as well as code from Luca Barbieri to improve the pushbuf
interface, which just happens to break nouveau's libdrm ABI so was delayed
until now.

API changes as a result of 0.0.16 DRM interface:

1. No more bo_pin()/bo_unpin(), these were only there for UMS and we no
   longer support it.

2. Any random nouveau_bo can be submitted to the GPU as a push buffer.

3. Relocations can be applied on any nouveau_bo

This patch changes the pushbuffer ABI to:

1. No longer use/expose nouveau_pushbuffer. Everything is directly
   in nouveau_channel. This saves the extra "pushbuf" pointer dereference.

2. Use cur/end pointers instead of tracking the remaining size.
   Pushing data now only needs to alter cur and not both cur and remaining.

The goal is to make the *_RING macros faster and make the interface simpler
and cleaner in the process.

The *_RING APIs are unchanged, but those are inlined and the ABI is changed.

Also, anything accessing pushbuf->remaining instead of using AVAIL_RING
will need to be fixed.

intel: Handle resetting of input params after EINTR during SET_TILING

The SET_TILING is pernicious in that it overwrites the input arguments
following an error in order to report the current tiling state of the
buffer. This caught us by surprise as we then fed those arguments back
into to the ioctl unmodified following an EINTR and so the kernel then
reported success for the no-op. We interpreted this success as meaning
that the tiling on the buffer had changed so updated our state and
started using the buffer incorrectly in the new tiled/untiled manner.
This lead to all sorts of random corruption and GPU hangs, even though
the batch buffers would look sane (when the GPU had not wandered off
into forbidden territory).

intel: Account for potential pinned buffers hogging fences

As the kernel reports the total number of fences, we must guess how many
fences are likely to be pinned. In the typical system these will be only
used by the scanout buffers, of which there may be one per pipe, and any
number of manually pinned fenced buffers. So take a conservative guess
and reserve two fences for use by the system.

Note this reduces the number of fences to 3 for i915 and prior.
