Adds support for "state object" cmdstream buffers which can be
constructed once, and re-used many times. This enables the use
for CP_SET_DRAW_STATE packets on newer hardware, to lower the
CPU overhead.

Splitting code-motion out from next patch. Once we add stateobj rb's
this loop could add new entries to bos table, so it needs to be before

Add new API for reusable "state objects" which can be re-used multiple
times. Backend implementation for msm will follow. (Probably not
needed to support this for any device that uses kgsl backend, since this
is mostly useful for a5xx+.)

In mesa/gallium, a pipe_fence can outlive the pipe_context it was
created from. But to wait on the fence we need to know the submit-
queue (ie. the fd_pipe).
The most straightforward way to fix this is to add reference counting
to the fd_pipe and let the fence hold a reference to the pipe (rather
than hanging on to the context, which might have been destroyed before
the fence).

Needed for clover/OpenCL. Fortunately the kernel interface is already
in place.
Include a stub _put_iova() so mesa can tell us when it no longer needs
the buffer to be pinned. There is no kernel interface for this (yet),
but at least if we want to unpin buffers we won't need mesa changes.

In case of a kernel that is new enough to support multiple submit-
queues, but with an adreno generation which doesn't support multiple
prioritized ringbuffers, we'd attempt to open a submit-queue with
prio=1 (medium), which is rejected by the kernel.
This could happen either w/ an older mesa (which uses fd_pipe_new())
or a newer mesa which defaults to prio=1 if no pipe context priority
flags are set.
The simple answer to fix both cases is to clamp the requested priority
according to the number of rings. This might not do exactly what you
want, if we hypothetically had 2 rings (it would result in requested
medium priority being high priority instead of low priority). But the
number of rings (for hw gen's that support this) is purely a software
construct, so the easy answer there is to have the kernel advertise at
least 3 rings if it supports more than one. There isn't really any
reason to do otherwise.
