The following situation can happen in a multithreaded OpenGL application.
A BO is submitted from etna_cmd_stream #1 with flags set for read.
A BO is submitted from etna_cmd_stream #2 with flags set for write.
This triggers a flush on stream #1 and clears the BO's current_stream
pointer. If at this point, stream #2 attempts to queue BO again, which
does happen, the BO will be added to the submit list twice. The Linux
kernel driver correctly detects this and warns about it with "BO at
index %u already on submit list" kernel message.
However, when cleaning the BO cache in etna_bo_cache_free(), the BO
which was submitted twice will also be free()d twice, this triggering
a glibc double free detector.
The fix is easy, even if the BO does not have current_stream set,
iterate over current streams' list of BOs before adding the BO to it
and verify that the BO is not yet there.

In which /tmp/a.txt contains the public symbols from
etnaviv-symbol-check. The idea here will be to switch the default
visibility to hidden so we don't export symbols we shouldn't.

This will prevent any more missing `#include "config.h"` bug, at the
cost of having to recompile some files that didn't need to be when
changing build options.

Add etna_cmd_stream_perf(..) to submit perform requests.
Userspace can submit pmrs via submit ioctl to sample perfmon
signals.
v3:
- mark perfmon bos as RW

It is safe to submit the full struct even on older kernels as such
kernels do not process the full struct. Without this change it
becomes quite challenging to extned the submit struct.
Freedreno has no special treatment too. See git commits
- freedreno: sync uapi header
- freedreno: add fence fd support
