Review carefully, it sucks to have to keep track of the number of
command packet dwords emitted in the batch epilogue manually. The
MI_REPORT_PERF_COUNT_BATCH_DWORDS calculation was obviously wrong.

Both the AMD and Intel APIs provide a dataSize parameter, and this
function would merrily ignore it. Neither API specifies what to do when
the buffer isn't big enough. I take the easy route of writing all the
complete bits of data that will fit. With more complete specs, we could
probably do something different.
I noticed this while looking into an unused parameter warning. The
warning was actually useful!

This patch reduces the likelihood of pointer arithmetic overflow bugs in
gather_oa_results(), like the one fixed by b69c7c5dac.
I haven't yet encountered any overflow bugs in the wild along this
patch's codepath. But I get nervous when I see code patterns like this:
(void*) + (int) * (int)
I smell 32-bit overflow all over this code.
This patch retypes 'snapshot_size' to 'ptrdiff_t', which should fix any
potential overflow.

For a long time, we've wanted a place to put utility code which isn't
directly tied to Mesa or Gallium internals. This patch creates a new
src/util directory for exactly that purpose, and builds the contents as
libmesautil.la.
ralloc seemed like a good first candidate. These days, it's directly
used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl
didn't make much sense.

I guarded half of the callers to start/stop_oa_counters with generation
checks, but missed the other half (which were added later). OACONTROL
doesn't exist on Ironlake, so we better not write it. Also, there's no
need---Ironlake's performance counters are always running.
This patch moves the generation checks into start/stop_oa_counters,
rather than requiring the caller to do them.
Fixes assertion failures in Piglit's AMD_performance_monitor/measure.

Unfortunately, our hardware only has one set of aggregating performance
counters shared between all 3D programs, and their values are not saved
or restored by hardware contexts. Also, at least on Sandybridge and
Ivybridge, the counters lose their values if the GPU goes to sleep.
To work around both of these problems, we have to snapshot the
performance counters at the beginning and end of each batch, similar to
how we handle query objects on platforms that don't support hardware
contexts. I call these "bookend" snapshots.
Since there can be multiple performance monitors active at a time, we
store the bookend snapshots in a global BO, shared by all monitors.
For monitors that span multiple batches, acquiring results involves
adding up three segments:
BeginPerfMonitor --> End of Batch 1 ("head")
Start of Batch 2 --> End of Batch 2
... ("middle")
Start of Batch N-1 --> End of Batch N-1
Start of Batch N --> EndPerfMonitor ("tail")
Monitors that refer to bookend BO snapshots are considered "unresolved".
We delay resolving them (and adding up deltas to obtain the results) as
long as possible to avoid blocking on mapping monitor->oa_bo.
We can also run out of space in the bookend BO, at which point we have
to resolve all unresolved monitors. Then we can throw away the
snapshots and begin writing at the beginning of the buffer.

We need to start OA at the beginning of each batch where monitors are
active. OACONTROL isn't part of the hardware context, so to avoid
leaving counters enabled for other applications, we turn them off at the
end of the batch too.
We also need to start them at BeginPerfMonitor time (unless they've
already been started). We stop them when the monitor last ends as well.

counters to a buffer. Exactly how it works varies between generations:
Ironlake requires two packets, Sandybridge has to use GGTT, and Ivybridge
and later use PPGTT.

In addition to listing the counter names, we include several "remap"
tables. Confusingly, counters are documented with names like "A23",
are written to some buffer offset other than 23, and exposed by core
Mesa under a counter ID that is different still.
The first is inevitable; MI_REPORT_PERF_COUNT writes certain counters to
fixed locations in the buffer. The latter could be avoided, but core
Mesa uses the "Counters" array index as the ID for a counter. We could
do remapping there, but it would just complicate the core Mesa code.

This is fairly simple:
- At BeginPerfMonitor time, take an opening snapshot.
- At EndPerfMonitor time, take a closing snapshot.
- The first time the application asks for results, subtract the two and
store that value. Then free the BO containing the snapshots.
- On subsequent requests for the results, just return the saved value.
- On reset, throw away the results.

For now, we only support these on Gen6+, since that's what currently
uses hardware contexts. When we add Ironlake hardware context support,
we can add pipeline statistics register support for that as well.
In theory, we could support pipeline statistics counters even without
hardware contexts, but it would be annoyingly painful.

This reverts most of commit 0f2da773070c06b6d20ad264d3abb19c4dfd9761.
(I chose to leave the additions to brw_defines.h.)
My previous Ironlake implementation was somewhat broken: counter data
was global, rather than per-context. This meant that performance
monitors captured data from your compositor, 2D driver, and other 3D
programs.
Originally, I believed that Sandybridge and later had an easy way to
avoid this problem (setting per-context flags in OACONTROL), while
Ironlake did not. So I'd intended to leave it as a known limitation of
performance monitoring support on Ironlake. However, this turned out
not to be true.
Unfortunately, our hardware only has one set of aggregating performance
counters shared between all 3D programs, and their values are not saved
or restored by hardware contexts. Also, at least on Sandybridge and
Ivybridge, the counters lose their values if the GPU goes to sleep.
To work around both of these problems, we have to snapshot the
performance counters at the beginning and end of each batch, similar to
how we handle query objects on platforms that don't support hardware
contexts.
For occlusion queries, this batch bookending approach is fairly simple:
only one occlusion query can be active at a time, and the result is a
single integer. Performance monitors are more complex: an arbitrary
number of monitors can be active at a time, each monitoring some subset
of our ~30 observability counters. Individual monitors can be started
and stopped at any point during the batch. Tracking where each monitor
started/ended relative to batch flushes ends up being a pain. And you
can run out of space in the buffer.
Properly supporting this required some serious rearchitecting of the
code. Rather than writing patches to try and morph a broken system into
a working one (which operates quite differently), I decided it would be
simplest to revert the old code and start fresh. Parts will look
familiar, but other parts are new.
I also decided it would be best to include Sandybridge and Ivybridge
support from the start, since the newer platforms have added complexity
that I wanted to make sure worked. They're also what most people care
about these days.

Ironlake's counters are always enabled; userspace can simply send a
MI_REPORT_PERF_COUNT packet to take a snapshot of them. This makes it
easy to implement.
The counters are documented in the source code for the intel-gpu-tools
intel_perf_counters utility.
v2: Adjust for core data structure changes. Add a table mapping buffer
object offsets to exposed counters (which changes each generation).
Finally, add report ID assertions to sanity check the BO layout
(thanks to Carl Worth).
v3: Update for core BeginPerfMonitor hook changes (requested by Brian).
