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.

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.

Apply workaround for Wayland set_queue race
Wayland objects receive events from the server into an event queue.
Unless specified otherwise, events from the server arrive to the event
queue belonging to the parent object. It is beneficial for us to
override this default queue assignment so that we receive only the
events we are interested in.
We currently override the default event queue assignment using
wl_proxy_set_queue after object construction:
struct wl_object *child_object = wl_create_object(parent_object);
wl_proxy_set_queue((struct wl_proxy *)child_object, queue);
There is a race condition here: events may be received into the parent's
queue before we have a chance to perform this override. This will lead
to hangs if we are expecting an event to arrive to our specific queue.
To workaround this issue, we can use a wrapper object to specify the
desired event queue at the time of object creation:
struct wl_object *parent_wrapper = wl_proxy_create_wrapper(parent_object);
wl_proxy_set_queue((struct wl_proxy *)parent_wrapper, queue);
struct wl_object *child_object = wl_create_object(parent_wrapper);
wl_proxy_wrapper_destroy(parent_wrapper);
This commit applies this workaround to all object allocations whose
intended event queues differ from the default assignment to avoid the
aforementioned race condition.

In vkCreateDevice:
- ppEnabledExtensionNames is extended with device extensions required
by the layer.
- if the extensions are not supported by the physical device, the
layer fails to initialize the device.

util: add class for storing extensions strings

Use util::allocator in swapchain object
Change util::allocator's create and destroy methods so that they can
allocate multiple objects, in line with the allocate and deallocate
methods of std::allocator.
Also add documentation for util::allocator and its methods.
Finally, use util::allocator in swapchain.cpp, rather than allocating
memory directly via VkAllocationCallbacks.

Implement a vector utility that uses a custom allocator
Add util::vector to provide functionality similar to std::vector,
i.e. growable arrays. util::vector does its allocations via a custom
allocator provided via VkAllocationCallbacks and provides methods to
check whether the allocation fails, e.g. try_push_back() returns false
when the allocation fails and replaces std::vector's push_back() method
that would rather raise an exception to report an allocation failure.
Note that this commit switches on exceptions in the layer by removing
the flag -fno-exceptions.
util::vector is also used to store swapchain images.

Remove use of pthread_cancel in the swapchain page flip thread
The WSI layer may call pthread_cancel and kill the page flip
thread while it's still being used in Vulkan-API calls. This can cause the
layer to fail to clean up internal resources of the associated device,
leading to memory leaks. To resolve this, the layer now instead checks
if the page flip thread needs to end on every loop iteration. The
m_page_flip_semaphore has also been changed to a timed_semaphore to avoid
hanging indefinitely. In addition, m_page_flip_thread is now type
std::thread, which follows the gradual move towards C++ standard code
and moved to a private member function of the class.

Initial sources for the vulkan-wsi-layer project
This commit adds the initial sources for the vulkan-wsi-layer project:
a Vulkan layer which implements some of the Vulkan window system
integration extensions such as VK_KHR_swapchain.
The layer is designed to be GPU vendor agnostic when used as part of the
Vulkan ICD/loader architecture.
The project currently implements support for VK_EXT_headless_surface and
its dependencies. We hope to extend support for further platforms such
as Wayland and direct-to-display rendering in the future.
This initial commit collects contributions from different individuals
employed by Arm.
More information on the project (building instructions, how to
contribute, etc.) can be found on the README.md file at the top of the
project tree.
