loader_dri3: Honor the request to preserve back buffer content

EGL uses the force_copy parameter to loader_dri3_swap_buffers_msc() to indicate
that it wants to preserve back buffer contents across a buffer swap.

While the loader then turns off server-side page-flipping there's nothing to
guarantee that a new backbuffer isn't chosen when EGL starts to render again,
and that buffer's content is of course undefined.

So rework the functionality:
If the client supports local blits, allow server-side page flipping and when
a new back is grabbed, if needed, blit the old back's content to the new back.
If the client doesn't support local blits, disallow server-side page-flipping
to avoid a client deadlock and then, when grabbing a new back buffer, sleep
until the old back is idle, which may take a substantial time depending on
swap interval.

glxSwapBuffers, for example, doesn't require a current context and that was a

st/va: change frame_idx from array to hash table

The picture_id was assumed to be a frame number so in 0-31.
But the vaapi client gstreamer-vaapi uses the surfaces handles
as identifier which are unsigned int.

This bug can happen when using a lot of vaapi surfaces within

surface ID: mesa/util/u_handle_table.c::handle_table_add which
starts from 0 and incremented by 1 at each call.
So creating more than 32 surfaces was a problem.

The following bug contains a test that reproduces the problem
by running a couple of vaapih264enc in the same process. The
above also explains why there was no pb when running them in

Mesa will map user defined vertex input attributes to slots

in Vulkan we can expose up to 28 (which are also mapped from

we scope the size of the array of attribute workaround flags

glsl: stop cloning builtin fuctions _mesa_glsl_find_builtin_function()

The cloning was introduced in f81ede469910d to fix a problem with
shaders including IR that was owned by builtins.

However the approach of cloning the whole function each time we
reference a builtin lead to a significant reduction in the GLSL
IR compilers performance.

The previous patch fixes the ownership problem in a more precise
way. So we can now remove this cloning.

Testing on a Ryzen 7 1800X shows a ~15% decreases in compiling the

glsl: pass mem_ctx to constant_expression_value(...) and friends

The main motivation for this is that threaded compilation can fall
over if we were to allocate IR inside constant_expression_value()
when calling it on a builtin. This is because builtins are shared
across the whole OpenGL context.

f81ede469910d worked around the problem by cloning the entire
builtin before constant_expression_value() could be called on
it. However cloning the whole function each time we referenced
it lead to a significant reduction in the GLSL IR compiler
performance. This change along with the following patch
helps fix that performance regression.

Other advantages are that we reduce the number of calls to
ralloc_parent(), and for loop unrolling we free constants after
they are used rather than leaving them hanging around.
