Duplicate source files for Vulkan.
The Vulkan implementation needs a directory for each architectural
layer, similar to the OpenGL ES stack. The entire rendering stack is
duplicated, leaving only Reactor common between them:
Renderer -> Device
Shader -> Pipeline
Common -> System
Main -> WSI

+// On Android Virtual Devices we heavily depend on logging, even in
+// production builds. We do this because AVDs are components of larger
+// systems, and may be configured in ways that are difficult to
+// reproduce locally. For example some system run tests against
+// third-party code that we cannot access. Aborting (cf. assert) on
+// unimplemented functionality creates two problems. First, it produces
+// a service failure where none is needed. Second, it puts the
+// customer on the critical path for notifying us of a problem.
+// The alternative, skipping unimplemented functionality silently, is
+// arguably worse: neither the service provider nor the customer will
+// learn that unimplemented functionality may have compromised the test
+// results.
+// Logging invocations of unimplemented functionality is useful to both
+// service provider and the customer. The service provider can learn
+// that the functionality is needed. The customer learns that the test
+// results may be compromised.
