Jason Ekstrand e73d136a02 vulkan/wsi/x11: Implement FIFO mode.
This implements VK_PRESENT_MODE_FIFO_KHR for X11.  Unfortunately, due to
the way the present extension works, we have to manage the queue of
presented images in a separate thread.

Jason Ekstrand 4fa0ca80ee vulkan/wsi: Report the correct min/maxImageCount
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.

Kevin Strasser 932bb3f0dd vulkan/wsi: Add a thread-safe queue implementation
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.

Without this fix, the function would still end up returning NULL but it
would put that NULL connection in the hash table which would be bad.

Eduardo Lima Mitev 129da27426 vulkan/wsi/x11: Smplify implementation of vkGetPhysicalDeviceSurfaceFormatsKHR
This patch simplifies x11_surface_get_formats(). It is actually just a
readability improvement over the patch I provided earlier this week
(750d8cad72).

Eduardo Lima Mitev b677b99db5 vulkan/wsi/x11: Fix behavior of vkGetPhysicalDeviceSurfacePresentModesKHR
x11_surface_get_present_modes() is currently asserting that the number of
elements in pPresentModeCount must be greater than or equal to the number
of present modes available. This is buggy because pPresentModeCount
elements are later copied from the internal modes' array, so if
pPresentModeCount is greater, it will overflow it.

On top of that, this assertion violates the spec. From the Vulkan 1.0
(revision 32, with KHR extensions), page 581 of the PDF:

    "If the value of pPresentModeCount is less than the number of
     presentation modes supported, at most pPresentModeCount values will be
     written. If pPresentModeCount is smaller than the number of
     presentation modes supported for the given surface, VK_INCOMPLETE
     will be returned instead of VK_SUCCESS to indicate that not all the
     available values were returned."

So, the correct behavior is: if pPresentModeCount is greater than the
internal number of formats, it is clamped to that many present modes. But
if it is lesser than that, then pPresentModeCount elements are copied,
and the call returns VK_INCOMPLETE.

This fix is similar (but simpler and more readable) than the one I provided
in 750d8cad72 for vkGetPhysicalDeviceSurfaceFormatsKHR, which was suffering
from the same problem.

     pSurfaceFormatCount must point to a variable set by the user to the

     variable is overwritten with the number of structures actually written
     to pSurfaceFormats. If the value of pSurfaceFormatCount is less than
