There is a race where the BO refcount might drop to 0 before the
dmabuf/name import paths had a chance to grab a reference for a
BO found in the handle_table. The easiest solution is to keep the
refcount stable as long as the table_lock is held.
While a more involved scheme of rechecking the refcount before
actually destroying the BO might also work, the bo_del path isn't
called very often, so micro-optimizing a single mutex_lock seems
to be over-engineered, so go for the easy solution.

This uses a meson builtin to handle -fvisibility=hidden. This is nice
because we don't need to track which languages are used, if C++ is
suddenly added meson just does the right thing.

Make sure the nano second part is less than one second. This matches
what clock_settime expects and allows for more concise kernel
interfaces.

When I was writing drm-shim, I was focused on the v3d kmsro case -- use my
intel device as the kmsro display device and add on a simulator-based v3d
device that we could render with. But for the noop backends we use for
shader-db, it's a lot more useful to just overwrite the first render node
in the system so that you don't have to pass a -d <how many render nodes I
already have in my system> argument.

If softpin is available on the kernel side, we transparently replace the
relocs with self-managed GPU virtual addresses. This allows to skip some
work at the kernel side, as it doesn't need to touch the command stream
anymore before submitting it to the hardware.

Reallocate the command stream buffer in case it is too small.
The older kernel versions are limited to 64 kiB buffer, so
limit the size to avoid oversized buffers.

This way we can ensure that the pipe driver tracking of pending resources
stays in sync with the actual command buffer state, even if a space

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.
