Description
This extension allows the application to query a 64-bit buffer device
address value for a buffer, which can be used to access the buffer memory
via the PhysicalStorageBufferEXT storage class in the
GL_EXT_buffer_reference
GLSL extension and
SPV_EXT_physical_storage_buffer
SPIR-V extension.
It also allows buffer device addresses to be provided by a trace replay tool, so that it matches the address used when the trace was captured.

Issues
1) Where is VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT and VkPhysicalDeviceBufferAddressFeaturesEXT?
RESOLVED: They were renamed as
VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_DEVICE_ADDRESS_FEATURES_EXT
and VkPhysicalDeviceBufferDeviceAddressFeaturesEXT accordingly for
consistency.
Even though, the old names can still be found in the generated header files
for compatibility.
