[intel-GEM] ref count objects in gtt-lru.
...
If objects on the lru aren't ref counted, they'll get pulled from the gtt as
soon as they are freed. This change does cause objects to get stuck in the
gtt until they're forced out by new requests. The lru should get cleaned
when the irq occurs.

[intel-GEM] Add memory domain support.
...
Memory domains allow the kernel to track which caches to flush and how to
move objects before buffer execution.

Monitor ACTHD register while polling for idle ring.
...
When batch buffers are executing, the ring may be stuck for a long time.
Monitor the ACTHD pointer which will show if the execution engine is
actually hung.

Unlock pages right after getting them.
...
pages come back from find_or_create_page locked, but must not stay locked
for long. Unlock them immediately instead of waiting until we're done with
them to avoid deadlock when applications try to touch them.

Add name/open ioctls, separate handle and pointer ref counts.
...
Names are just another unique integer set (from another idr object).
Names are removed when the user refernces (handles) are all destroyed --
this required that handles for objects be counted separately from
internal kernel references (so that we can tell when the handles are all
gone).

mixed 32/64 bit systems need 'special' help for ioctl where the user-space

and align the same way for both 32 and 64-bit ppc and x86 environments will
elimiante the need to have magic 32/64-bit ioctl translation code.
