292a3c14d7 Decouple creation, allocation and binding of images from Wayland backend
A lot of the steps involved in creating a VkImage, allocating backing
memory, and binding the VkImage to the memory do not rely specifically
on Wayland features and could be common to other WSI backends.

This commit attempts to decouple the create_and_bind_swapchain_image()
function in the wsi/wayland/swapchain.cpp from Wayland and wsialloc
specific parts, and instead move the independent parts related to
external memory management to a new external_memory class. This will
allow the independent code to be re-used in future WSI backends.

425b885f6e Fix issues found by static analysis
All of the issues that this patch fixes should not occur in practice,
but make the code a bit more robust. For example, this patch
default-initializes structures passed to Vulkan for initialization.
Normally, initialization should be done by the Vulkan entrypoint,
so it should be fine not initializing the structure as long as the
Vulkan API entrypoint exits with success status. It is still a good
idea to default-initialize anyway to make the behaviour deterministic
in cases where something is wrong in the system. All changes made
should have a negligible impact on performance for typical
applications.

dd1f3f24cc Enable instance extensions required by layer
The layer needs functionality that is not part of Vulkan 1.0 and is
provided by either Vulkan 1.1 or separate Vulkan extensions.
The layer used to solve this issue by bumping the API version passed
by the application in VkCreateInfo to 1.1 if this was set to 1.0.
This workaround does not seem to be working anymore with recent
versions of the loader. Fortunately, the loader now allows layers
to change the extension lists passed by the application.
This patch changes the layer to use this approach and removes the
API bump logic.

Documentation is updated accordingly.

2bc2109194 Add support for VK_EXT_image_compression_control_swapchain
Implement support for VK_EXT_image_compression_control_swapchain
for both the Wayland and the headless windowing systems.
The extension can be conditionally enabled through the new build option
BUILD_WSI_IMAGE_COMPRESSION_CONTROL_SWAPCHAIN. Compiling with this
option enabled requires recent Vulkan headers (1.3.213)
Note also that support in the layer is enabled conditionally to
the ICD supporting VK_EXT_image_compression_control.

Update the WSIALLOC interface to version 2 and add support to
prefer selection of a format with the highest fixed rate compression
from the formats provided. This is used to pick a fixed rate
compression when VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT is
specified during swapchain creation.

ba0684b5e0 Mark fences and semaphores as already signalled in AcquireNextImage
The VK_KHR_external_[fence|semaphore]_fd extensions allow sync
primitives to be signalled without the use of QueueSubmit. Using these
extensions in AcquireNextImage instead of using QueueSubmit offers two
advantages: (1) there is no waiting for work to complete in the queue
before the primitives are signalled and (2) there is no data race if
the application happens to call QueueSubmit on the same queue at the
same time.

The QueueSubmit method of signalling sync primitives continues to be
used for ICDs that do not support the external FD extensions.

e78252429a Fix FD ownership issue in Wayland Vulkan import
When a file descriptor is imported in Vulkan as a dma buf the Vulkan
implementation takes ownership. We use this property to manage the
lifetime of file descriptors allocated by WSIALLOC by importing them as
VkDeviceMemory. After import the WSI Layer doesn't need to close any
file descriptors and instead only needs to destroy the VkDeviceMemory
object.

However after import the original file descriptor should not be used by
the application. Currently the WSI Layer Wayland implementation violates
this by using the FD to pass to the compositor. This commit fixes the
issue by initiating the Wayland requests before importing the fd.
Internally libwayland will duplicate the fd.

0c7dcc9be9 Fix bug in has_descendant_started_presenting in headless backend
If there exists two swapchains where one is a descendant of another, we
need to return VK_ERROR_OUT_OF_DATE_KHR error if the application tries
to present from the ancestor when the descendant has started presenting.

The has_descendant_started_presenting() function checks whether the
descendant has started presenting by looking for pending images in the
descendant's list of swapchain images. However, the descendant could
have already presented its pending image(s) before the ancestor arrives
at this check. In this scenario, the descendant will have marked the
swapchain image(s) as now free, and therefore when the ancestor looks
for pending images it will fail to find any. This causes the function to
incorrectly return false.

This bug can be resolved by creating a new boolean member variable to
track whether the swapchain has started presenting.

d74a006c7b wsi: Fix swapchain teardown causing hangs
The swapchain teardown waits for pending images incorrectly. The
regression caused the wait to complete before pending images were
processed as well as a hang when all images are acquired by the
application or pending presentation. In this case the swapchain
teardown would hang waiting on the last image presented by a compositor
that would never be released.

Fixing this exposes additional hangs when swapchain images update the
free semaphore after being marked as free. There are also potential
hangs if multiple threads are waiting for all pending images or
acquiring an image at the same time. These issues are addressed by
serializing those actions with a mutex.

ba54f0e9ca Remove destroy_image from unpresent function
Fixes an issue, where in Wayland the new swapchain hanged during its
first image presentation in the page flipping thread when it waited for
the old swapchain to finish presenting its pending images. As the new
swapchain had started presenting destroy_image was called during the
unpresent function for the old swapchain and the image's status was set
to INVALID instead of FREE. So free_image_found never returned true and
subsequently get_free_buffer was blocked in the loop. The issue is fixed
by removing the call to destroy_image in unpresent_image as it is
redundant and is done in swapchain teardown.

6282185808 wayland: Add format negotiation
Replaces the default format used on swapchain image allocation. Instead
the format is negotiated between the supported formats by the Wayland
compositor the Vulkan ICD and any external system allocator.

24f18c6c44 wsi: Move common objects to the wayland wsi::surface
Moves data and Wayland objects such as the registry to the
wsi::wayland::surface implementation. This also fixes a few issues
with queries where the Wayland display's default queue was wrongly
used and minimizes leaking of server memory from registry creation.

Moves the ownership of the zwp_linux_dmabuf_interface object to the
wsi::wayland::surface as it can be shared between swapchains.

Fixes issues with casting VkSurfaces in the Wayland backend that can
fail when using other layers that wrap the object.

c7be05e3ff Implement objects associated with VkSurface
Defines an abstract wsi::surface object to be implemented by each WSI
backend. This object is then associated with the corresponding VkSurface
object in the instance specific data.

To keep track of these objects the layer now intercepts
vkDestroySurfaceKHR, while specific surface creation entrypoints are
intercepted by individual WSI backends.

In addition this change should allow for fixing incompatibility issues
with layers that wrap VkSurface which breaks casting to the Loader's ICD
VkSurface type.

Make greater use of util::unique_ptr and allow for such pointers to be
constructable when casting derived types.

feb2445f2a Fix potential hang on swapchain inheritance
Introduce a mutex to control access to a swapchain's image statuses,
also only wait for swapchain images marked as "PENDING"
