This will eventually be generated at the QIR level, so that
vc4_qir_schedule.c can arrange the separation of tex_strb from tex_result
correctly. It will also be important so that register allocation set the
register classes appropriately for values that are live across the switch.
This is a port of commit a4a59172482d50318a5ae7f99021bcf0125e0f53:
Add guards to prevent dereferencing NULL dynamic pipeline state. Asserts
of pCreateInfo members are moved to the earliest points at which they
should not be NULL.
This fixes a segfault, related to pColorBlendState, seen in Talos Principle
which I've observed after startup is completed and when exiting the menus,
depending on when Vulkan rendering is selected.
v2: moved the NULL check in radv_pipeline_init_blend_state to after the
declarations.

There is currently no protection against walking a hash (using
_mesa_HashWalk()) and modifying it at the same time, for instance by inserting
or deleting elements. This leads to segfaults in multithreaded code if e.g.
someone calls glTexImage2D (which may have to walk the list of FBOs) while
another thread is calling glDeleteFramebuffers on another thread with the two
contexts sharing lists.
The reason for this is that _mesa_HashWalk() doesn't actually take the mutex
that normally protects the hash; it takes an entirely different mutex.
Thus, walks are only protected against other walks, and there is also no
outer lock taking this. There is an old comment saying that this is to fix
problems with deadlock if the callback needs to take a mutex; we solve this
by changing the mutex to be recursive.

From the Vulkan spec 1.0.32 section 29.6 docs for vkAcquireNextImageKHR:
"Let n be the total number of images in the swapchain, m be the value of
VkSurfaceCapabilitiesKHR::minImageCount, and a be the number of
presentable images that the application has currently acquired (i.e.
images acquired with vkAcquireNextImageKHR, but not yet presented with
vkQueuePresentKHR). vkAcquireNextImageKHR can always succeed if a ≤ n -
m at the time vkAcquireNextImageKHR is called. vkAcquireNextImageKHR
should not be called if a > n - m with a timeout of UINT64_MAX; in such
a case, vkAcquireNextImageKHR may block indefinitely."
With minImageCount == 2 (as it was previously, the client is allowed to
acquire all but one image withoutblocking. If we really need 4 images for
mailbox mode + pageflipping, then we need to request a minimum of 4 images
up-front. This is a bit unfortunate because it means we will always
consume 4 images. In the future, we may be able to optimize this a bit by
waiting until the server starts to flip and returning OUT_OF_DATE to get
the client to re-allocate with more images or something like that.

In order to support FIFO mode without blocking the application on calls
to vkQueuePresentKHR it is necessary to enqueue the request and defer
calling the server until the next vblank period. The xcb present api
doesn't offer a way to register a callback, so we will have to spawn a
worker thread that will wait for a request to be added to the queue, call
to the server, and then make the image available for reuse. This commit
introduces the queue data structure needed to implement this.

If the user did not request full linking, link the shader with the

This gives it some chance of being useful.
