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.

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.

Fixes the wrong allocation of extensions properties.
Adds a call to the dispacher's DestroyInstance function before the
destruction of the instance.

Erroneous assert was left in swapchain_base.cpp after some refactoring
was done. This commit removes the assert and updates the CMakeLists.txt
file to turn on compiler warnings so that developers can spot these
leftover code earlier.

Vulkan Headers removed VK_FORMAT_RANGE_SIZE. The VkFormat enum now
has valid values in multiple ranges for different extensions.
Fixes headless implementation for itterating over core Vulkan 1.0
formats.

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.

Move all WSI type specific calls to WSI factory methods. This
removes headless references in layer/ and allows for simpler
support of multiple windowing systems.

The test just ensures the code can be built. For now we start from a
Fedora image and install quite a number of packages. This is not very
friendly in terms of network bandwidth. We should address this by
uploading a custom image in the future.

A couple of details in the installation instructions needed updating.
Also fixed a warning message due to a missing return statement (the
return value is currently not used in calls to the function).

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.
