ddebug: rewrite to always use a threaded approach
This patch has multiple goals:
1. Off-load the writing of records in 'always' mode to another thread
for performance.
2. Allow using ddebug with threaded contexts. This really forces us to
move some of the "after_draw" handling into another thread.
3. Simplify the different modes of ddebug, both in the code and in
the user interface, i.e. GALLIUM_DDEBUG. In particular, there's
no 'pipelined' anymore, since we're always pipelined; and 'noflush'
is replaced by 'flush', since we no longer flush by default.
4. Fix the fences in pipelining mode. They previously relied on writes
via pipe_context::clear_buffer. However, on radeonsi, those could
(quite reasonably) end up in the SDMA buffer. So we use the newly
added PIPE_FLUSH_{TOP,BOTTOM}_OF_PIPE fences instead.
5. Improve pipelined mode overall, using the finer grained information
provided by the new fences.
Overall, the result is that pipelined mode should be more useful, and
using ddebug in default mode is much less invasive, in the sense that
it changes the overall driver behavior less (which is kind of crucial
for a driver debugging tool).
An example of the new hang debug output:
Gallium debugger active.
Hang detection timeout is 1000ms.
GPU hang detected, collecting information...
Draw # driver prev BOP TOP BOP dump file
-------------------------------------------------------------
2 YES YES YES NO /home/nha/ddebug_dumps/shader_runner_19919_00000000

5 YES NO YES NO /home/nha/ddebug_dumps/shader_runner_19919_00000003
Done.
We can see that there were almost certainly 4 draws in flight when
the hang happened: the top-of-pipe fence was signaled for all 4 draws,
the bottom-of-pipe fence for none of them. In virtually all cases,
we'd expect the first draw in the list to be at fault, but due to the
GPU parallelism, it's possible (though highly unlikely) that one of
the later draws causes a component to get stuck in a way that prevents
the earlier draws from making progress as well.
(In the above example, there were actually only 3 draws truly in flight:
the last draw is a blit that waits for the earlier draws; however, its
top-of-pipe fence is emitted before the cache flush and wait, and so
the fact that the draw hasn't truly started yet can only be seen from a
closer inspection of GPU state.)

winsys/amdgpu: handle cs_add_fence_dependency for deferred/unsubmitted fences
The idea is to fix the following interleaving of operations
that can arise from deferred fences:
Thread 1 / Context 1 Thread 2 / Context 2
-------------------- --------------------
f = deferred flush
<------- application-side synchronization ------->
fence_server_sync(f)
...
flush()
flush()
We will now stall in fence_server_sync until the flush of context 1
has completed.
This scenario was unlikely to occur previously, because applications
seem to be doing
Thread 1 / Context 1 Thread 2 / Context 2
-------------------- --------------------
f = glFenceSync()
glFlush()
<------- application-side synchronization ------->
glWaitSync(f)
... and indeed they probably *have* to use this ordering to avoid
deadlocks in the GLX model, where all GL operations conceptually
go through a single connection to the X server. However, it's less
clear whether applications have to do this with other WSI (i.e. EGL).
Besides, even this sequence of GL commands can be translated into
the Gallium-level sequence outlined above when Gallium threading
and asynchronous flushes are used. So it makes sense to be more
robust.
As a side effect, we no longer busy-wait on submission_in_progress.
We won't enable asynchronous flushes on radeon, but add a
cs_add_fence_dependency stub anyway to document the potential
issue.

st/mesa: guard sampler views changes with a mutex
Some locking is unfortunately required, because well-formed GL programs
can have multiple threads racing to access the same texture, e.g.: two
threads/contexts rendering from the same texture, or one thread destroying
a context while the other is rendering from or modifying a texture.
Since even the simple mutex caused noticable slowdowns in the piglit
drawoverhead micro-benchmark, this patch uses a slightly more involved
approach to keep locks out of the fast path:
- the initial lookup of sampler views happens without taking a lock
- a per-texture lock is only taken when we have to modify the sampler
view(s)
- since each thread mostly operates only on the entry corresponding to
its context, the main issue is re-allocation of the sampler view array
when it needs to be grown, but the old copy is not freed
Old copies of the sampler views array are kept around in a linked list
until the entire texture object is deleted. The total memory wasted
in this way is roughly equal to the size of the current sampler views
array.

Notably, this is only supposed to affect output variables. Furthermore,
"Only variables output from a shader can be candidates for invariance."
It looks like this has been wrong since we first supported the pragma in

mesa: Add new fast mtx_t mutex type for basic use cases
While modern pthread mutexes are very fast, they still incur a call to an
external DSO and overhead of the generality and features of pthread mutexes.
Most mutexes in mesa only needs lock/unlock, and the idea here is that we can
inline the atomic operation and make the fast case just two intructions.
Mutexes are subtle and finicky to implement, so we carefully copy the
implementation from Ulrich Dreppers well-written and well-reviewed paper:
"Futexes Are Tricky"
http://www.akkadia.org/drepper/futex.pdf
We implement "mutex3", which gives us a mutex that has no syscalls on
uncontended lock or unlock. Further, the uncontended case boils down to a
cmpxchg and an untaken branch and the uncontended unlock is just a locked decr
and an untaken branch. We use __builtin_expect() to indicate that contention
is unlikely so that gcc will put the contention code out of the main code
flow.
A fast mutex only supports lock/unlock, can't be recursive or used with
condition variables. We keep the pthread mutex implementation around as
for the few places where we use condition variables or recursive locking.
For platforms or compilers where futex and atomics aren't available,
simple_mtx_t falls back to the pthread mutex.
The pthread mutex lock/unlock overhead shows up on benchmarks for CPU bound
applications. Most CPU bound cases are helped and some of our internal
bind_buffer_object heavy benchmarks gain up to 10%.

i965: properly initialize brw->cs.base.stage to MESA_SHADER_COMPUTE
This has a bit of a surprising effect:
For the render pipeline, the upload_sampler_state_table atom emits
3DSTATE_BINDING_TABLE_POINTERS_XS. It tries to avoid this for compute:
if (GEN_GEN >= 7 && stage_state->stage != MESA_SHADER_COMPUTE) {
/* Emit a 3DSTATE_SAMPLER_STATE_POINTERS_XS packet. */
genX(emit_sampler_state_pointers_xs)(brw, stage_state);
} ...
However, we were failing to initialize brw->cs.base.stage, so it was
left as 0 (MESA_SHADER_VERTEX), causing this condition to break. We
then emitted 3DSTATE_SAMPLER_STATE_POINTERS_VS in GPGPU mode, when
trying to upload CS samplers. Nothing good can come of this.
Found by inspection while debugging a GPU hang. Jordan believes this
helps the Deus Ex: Mankind Divided benchmark mode's stability when
